Full textAbstract:
Proof of Tunnel Signature (PoTS) is designed to avoid the main problems found in certificates based on Blockchain technology. In this case, it is so closely related to Cybersecurity. A lightweight protocol such as a Certificate Authenticated Key Agreement (CAKA) is needed to reduce the vulnerability of a system's operation, namely overcoming management overhead by using a decentralized system according to the characteristics of Blockchain Technology. PoTS is the second stage after determining the Key Agreement (KA) or certificate hash in authenticating a node, and this is also a significant step in minimizing computation costs. The nodes generated after the signing process remain anonymous and can be verified optimally. Smart contracts are also used as a support so that this research can ensure transparency and openness of transaction nodes to maintain and improve the efficiency of transaction security for a certificate based on Blockchain Technology.

Credit take over is a payment made by a third party to a creditor, who will replace his position as a new creditor to the debtor. The absence of standard rules regarding the implementation of credit take over has resulted in non-standardization of the credit take over implementation process. The purpose of this article is to examine the legal protection of the parties in implementing the take over at Bank Jatim Banyuwangi Branch. This type of research is empirical legal research where the study was conducted at Bank Jatim Banyuwangi Branch. The results of research conducted by a Notary/PPAT in Banyuwangi are included in the category of subrogation by way of law (Article 1403 of the Civil Code). In the implementation of take over credit protection is obtained through the re-signing of the SKMHT at the time of the Roya Letter, and a certificate of proof of ownership of the guarantee has been physically issued by the initial creditor. The implementation of the take over for new creditors at Bank Jatim Banyuwangi Branch is obtained through the re-signing of the SKMHT which is the basis for making APHT when the roya letter, proof of credit repayment, and certificate of proof of collateral ownership have been physically issued by the initial creditor (bank). The initial check before the certificate of proof of ownership is issued by the initial creditor is carried out by issuing a Land Registration Certificate (SKPT) through the BPN.How to cite item: Firmansyah, F.

Full textAbstract:
Current Transport Layer Security (TLS) Public-Key Infrastructure (PKI) is a vast and complex system; it consists of processes, policies, and entities that are responsible for a secure certificate management process. Among them, Certificate Authority (CA) is the central and most trusted entity. However, recent compromises of CA result in the desire for some other secure and transparent alternative approaches. To distribute the trust and mitigate the threats and security issues of current PKI, publicly verifiable log-based approaches have been proposed. However, still, these schemes have vulnerabilities and inefficiency problems due to lack of specifying proper monitoring, data structure, and extra latency. We propose Accountable and Transparent TLS Certificate Management: an alternate Public-Key Infrastructure (PKI) with verifiable trusted parties (ATCM) that makes certificate management phases; certificate issuance, registration, revocation, and validation publicly verifiable. It also guarantees strong security by preventing man-in-middle-attack (MitM) when at least one entity is trusted out of all entities taking part in the protocol signing and verification. Accountable and Transparent TLS Certificate Management: an alternate Public-Key Infrastructure (PKI) with verifiable trusted parties (ATCM) can handle CA hierarchy and introduces an improved revocation system and revocation policy. We have compared our performance results with state-of-the-art log-based protocols. The performance results and evaluations show that it is feasible for practical use. Moreover, we have performed formal verification of our proposed protocol to verify its core security properties using Tamarin Prover.

This study’s purpose was analyzing employee performance management in providing services to the community. The research method used was descriptive qualitative with technical data analysis using Miles, Huberman, and Saldana models. The results of the study indicated that employee performance management in the Birth Certificate service is carried out by producing a Birth Certificate that is in accordance with the truth of the data elements in the application file (on requirements) and the Population database. The Village Head/Village Secretary also always corrects the work of his employees before signing the file. The process of completing the Birth Certificate is also carried out very quickly so that people do not have to wait too long. The village government uses two methods, namely the manual method and online-based. This manual method is carried out if the process of issuing a Birth Certificate cannot be carried out through SIMADE. While this online-based service is carried out through SIMADE (Village Management Information System). SIMADE is an information system that can accommodate most administrative service activities at the Village office more quickly and accurately to help village officials to improve their performance in providing services

Abstract Digital signing of data in the Web-based IS is one of the most secure methods for guaranteeing the authenticity of data. Storage of user keys is particularly important for this methodology. The present development proposes a new algorithm for storage and usage of user keys for the database by the digital certificate of the client. The proposed methodology was designed for protection of data in a particular information system. One of the characteristics of this system is the great number of authorized users with rights for access and modification of various parts of data. With such systems it is extremely important to guarantee the authenticity of data stored in the system. Digital signing of data provides such guarantee of their authenticity.

With the development of computer architecture and its technologies in recent years, applications like e-commerce, e-government, e-governance and e-finance are widely used, and they act as active research areas. In addition, in order to increase the quality and quantity of the ordinary everyday transactions, it is desired to migrate from the paper-based environment to a digital-based computerized environment. Such migration increases efficiency, saves time, eliminates paperwork, increases safety and reduces the cost in an organization. Digital signatures are playing an essential role in many electronic and automatic based systems and facilitate this migration. The digital signatures are used to provide many services and solutions that would not have been possible by the conventional hand-written signature.
In the educational environment, the process of issuing the graduation certificates can no longer be restricted to the traditional methods. Hence, a computerized system for issuing certificates of graduation in an electronic form is needed and desired. This paper proposes a Graduation Certificates Issuing System (GCIS) based on digital signature technology. In doing so, this research highlights the state-of-the-art and the art-of-the-practice for some existing digital signature-based systems in the literatures. In addition, eight intertwined elected services are identified, namely: message authentication, entity authentication, integrity, non-repudiation, time stamping, distinguished signing authorities, delegating signing capability and supporting workflow systems. Moreover, this research examines nine existing systems, showing their merits and demerits in terms of these elected services. Furthermore, the research describes the architectural design using the Unified Modeling Language (UML) and provides the concrete implementation of the proposed GCIS. The GCIS is implemented using Visual Basic.Net programming language and SQL Server database management system.

In network security, digital signatures are considered a basic component to developing digital authentication systems. These systems secure Internet transactions such as e-commerce, e-government, ebanking, and so on. Many digital signature schemes have been researched and published for this purpose. In this paper, we propose two new types of collective signature schemes, namely i) the collective signature for several signing groups and ii) the collective signature for several individual signings and several signing groups. And then we used two difficult problems factoring and discrete logarithm to construct these schemes. To create a combination of these two difficult problems we use the prime module p with a special structure: p = 2n +1. Schnorr's digital signature scheme is used to construct related basic schemes such as the single signature scheme, the collective signature scheme, and the group signature scheme. The proposed collective signature schemes are built from these basic schemes. The proposed signature scheme is easy to deploy on existing PKI systems. It can support PKIs in generating and providing a unique public key, a unique digital signature, and a unique digital certificate for a collective of many members. This is essential for many collective transactions on today's Internet.

Full textAbstract:
Biometric systems input physical or personal human characteristics for identification, authentication, and security purposes. With the advancement in communication and intelligent security systems, biometrics are programmed to validate electronic signatures (E-signatures) for online and offline authentication. This article introduces a dynamic signature verification technique (DSVT) using mutual compliance (MC) between the security system and the biometric device. The security system is responsible for online and offline signature approval using personal inputs from humans. This personal verification is related to the stored online/offline signatures using certificates provided for authentication. The certificate-based authentication is valid within a session for online representation. Contrarily, this authentication is valid for persons under offline conditions. In this mode of segregation, application-level authentication verification is performed. A conventional tree classifier for dynamic signature verification is used for differentiating online and offline signatures. Moreover, the security metrics—such as signing bit, key, and size—are verified for both modes using classifier learning. For the segregated mode, the validation of the above is required to be unanimous to accelerate the dynamicity. The proposed technique’s performance is analyzed using the authentication success rate, verification failing ratio, verification time, and complexity.

With the rapid development of communication technology, unmanned aerial vehicles (UAVs) have been widely used in the military, rescue, agricultural and other fields. The security and privacy issues are one of the biggest challenges for UAV communications. In this paper, we propose a certificate signing based on an Elliptic Curve multiple authentication scheme (CSECMAS). The scheme employs multiple authentication tools to ensure the legitimacy of the identity and the integrity of the information. We treat multiple UAVs as a cluster, and after establishing a secure session between the ground control station (GCS) and the UAV, we use the fitness function to select one node from them as the key node. Mutual authentication between the UAVs through the key node establishes secure conversations while increasing the security and resistance to destruction of the entire communication network. The proposed protocol is formally analyzed and verified by using the model-checking tool SPIN. The informal analysis shows that the protocol can resist various attacks, such as man-in-the-middle attacks, replay attacks, and DoS attacks. The performance analysis shows that the proposed protocol is superior compared to other related protocols.

Vehicle Ad-hoc Networks (VANET) are considered among recent wireless communication technologies. Nowadays, vehicles are no more than simple means of transport, they are endowed with a source of intelligence through their interaction with the road environment due to embedded equipment on board vehicles and integrated into stations along roads and highways. The mechanisms of security and protection of messages exchanged in VANET, thus preserving the privacy of users and satisfying the various security requirements, are a prerequisite for the deployment of vehicle networks. Increasingly, several research have been proposed to improve protocols for maintaining security and preserving privacy. This paper presents a hierarchical revocable infrastructure based privacy preservation authentication protocol for vehicles that involves authentication of each vehicle and the corresponding Road Side Unit (RSU) by a Certification Authority (CA). The proposed protocol used Elliptic Curve Diffie Hellman (ECDH) algorithm for reliable key exchange and Edwards-curve Digital Signature Algorithm (EdDSA) to speed up the execution of the authentication process especially at the key management level, message signing and verification of this signature. On the other hand, the creation of sub-lists of revoked certificates based on vehicle type makes it possible to minimize the response time by looking for a certificate if it is revoked or not. Our solution was checked by the security verification tool, Automated Validation of Internet Security Protocols and Applications (AVISPA), which indicated that it is a very secure level. Performance analysis illustrates that the protocol greatly saves computation resources.

The results of the research concluded: 1) The process of granting credit to the BRI Unit Link Kajen Bank at the time of the guarantee there was still a transfer of rights, namely submission of applications, submission of complete documents accompanied by photocopies of the documents for submitting the transfer of property rights to the Land Office, Examination, Analysis of memorandums, approval from branch leadership, execution and disbursement of loans by the Bank to debtors. The process of granting credit to the BRI Unit Link Kajen Bank is carried out by making a written agreement so that it is binding for the parties and becomes a strong evidence base if one day there is a dispute. 2. Constraints and solutions in the process of granting credit to the BRI Unit Link Kajen Bank at the time of the guarantee there was still a transfer of rights, namely the frequent delays in the delivery of notary orders so that the Notary did not have time to check administrative completeness or confirm to BPN due to limited time. Another obstacle is the difficulty of managing the time so that the signing of the deed can be signed together. The solution that can be done is to provide counseling to the bank about the order procedure carried out to a notary and provide understanding to the bank so that the files that have been submitted to the notary have actually been approved by the prospective debtor, both interest and administrative and insurance costs.

Owing to the limitations of mobile terminals and network bandwidth, the current Secure Electronic Transaction (SET) protocol can not be introduced into mobile payment directly. Present mobile payment system often uses symmetric encryption algorithm that may bring in some security risks. A new secure mobile payment protocol based on ECC was presented ,which ensures information flows from merchant to customer and enhances the security of customer’s information. Theoretical analysis shows that, ECC can not only meet the requirements of short key generation time, but also ensure that at the same time of cracking code the ratio of RSA and ECC key length is greater than 5:1. The number of signing the certificate verification, asymmetric and symmetric encryption of the new protocol is also lesser than SET protocol, so the current mobile terminal and network capabilities can support this protocol to ensure safe and effective mobile payment process.

Full textAbstract:
Privacy protection and message authentication issues in VANETs have received great attention in academia. Many authentication schemes in VANETs have been proposed, but most of them are based on classical difficult problems such as factorization in RSA setting or Elliptic Curve setting and are therefore not quantum resistant. If a quantum computer becomes available in the next few decades, the security of these schemes will be at stake. This paper presents a vehicular lattice-based direct anonymous attestation (V-LDAA) scheme adopting an optimized signature scheme based on automorphism stability which achieves postquantum security. A distributed pseudonym update and vehicle revocation mechanism based on the lattice is introduced in this paper, which means vehicles can update their pseudonyms and revoke the identity certificate by themselves without the need for pseudonym resolutions or CRLs checking. Compared with the existing lattice-based attestation schemes in VANETs, computation costs during signing and verification operations in V-LDAA are no longer related to the number of users, which makes it suitable for large-scale VANETs. Security analysis shows that V-LDAA resists TPM theft attacks and provides users with user-controlled anonymity, user-controlled unlinkability, and unforgeability against quantum adversaries. Experimental results show that V-LDAA reduces the blind signature size by 18%. The speed of blind signing is increased by 30%, and blind verification operation is accelerated 3 times compared with the existing lattice-based direct anonymous attestation (LDAA) scheme.

This research was conducted with the aim of finding out how the validity of the status of buying and selling land which was carried out without a deed by the Land Deed Making Officer (PPAT) and how the settlement can be done by the buyer, so that buying and selling land carried out without a PPAT deed can have definite legal force. By using the normative juridical research method, it can be concluded that in buying and selling land which is carried out without a deed, the official making the land deed is a legal sale and purchase as long as it fulfills Article 1338 and Article 1320 of the Indonesian Civil Code, the problem faced is only a matter of proof in in the trial later, the settlement that can be carried out by the buyer, so that the sale and purchase of land carried out without a PPAT deed can have definite legal force by asking for a District Court Decision which gives legal certainty to the plaintiff as the legal owner of the land and buildings on it. With the decision of the District Court, the PPAT as the original holder of the certificate is required to submit the certificate for the land in question which is still registered in the name of the defendant to the plaintiff and his attorney. Because the defendant's place of residence is no longer known so that he cannot appear before the PPAT, the District Court's decision also gives permission and power of attorney to the plaintiff to act on behalf of the defendant (seller) in carrying out the signing of the deed of sale and purchase of land while simultaneously acting for and on his own behalf. the buyer at the price agreed at the time the sale and purchase of the lawsuit was carried out.

Full textAbstract:
Data transmission exists in almost all the Internet-based applications, while few of them consider the property of nonrepudiation as part of data security. If a data transmission scheme is performed without the endorsement of a trusted third party (TTP) or a central server, it is easy to raise disputes while transmitting valuable data, especially digital goods, because a dishonest participant can deny the fact of particular data transmission instance. The above problem can be solved by signing and encrypting. However, digital signature schemes usually assume public key infrastructure (PKI), increasing the burden on certificate management and are not suitable for distributed networks without TTP such as blockchain. To solve the above problems, we propose two new schemes for nonrepudiation data transmission based on blockchain (we call it BNRDT): one for short message transmission and the other for large file transmission. In BNRDT schemes, nonrepudiation evidence of data transmission is generated and stored on the blockchain to satisfy both the properties of nonrepudiation (including nonrepudiation of origin and nonrepudiation of receipt) and data confidentiality. We implement and test the schemes on Hyperledger Fabric. The experimental results show that the proposed schemes can provide appealing performance.

The Catholic Bishops' Conference of India (CBCI) Chair at Indira Gandhi National Open University (IGNOU) was established with the signing of a Memorandum of Understanding (MoU) between CBCI and IGNOU on 29 February 2000 to plan, design, develop and launch socially relevant programmes of study in the areas of HIV/AIDS social work, philosophy, etc. The one-time endowment grant of US$125,000 facilitates the programme development process without any financial contribution from IGNOU. In the 13 years of its existence, the CBCI Chair has developed eight programmes – from Certificate to Doctoral programmes. Some of these programmes have been revised. Over 30,000 students have enrolled for these programmes, which are being offered in 12 countries. Although the chair follows all the prescribed procedures for programme development and launch, the nature, scope and financial viability being enjoyed by the Chair facilitates timely decision making and achievement of targets. The CBCI Chair is a success story in Open and Distance Learning (ODL) as it has helped in the establishment of the first School of Social Work in ODL, the Centre for Tibetan Studies and the Mother Teresa Chair. The Chair has been instrumental in providing scholarships and awards to several students. This paper examined the what, why and how of the CBCI Chair and the implications it has as a model towards targeted interventions in ODL systems, quality assurance, maintenance and sustainability.

Credit take over agreements with guarantees of Mortgage Rights in the banking world can still be said to be attractive because CCB Indonesia Pekanbaru Branch is carrying out a binding agreement on take-over credit and Power of Attorney Imposing Mortgage Rights with the conditions of Land Rights Certificates and Mortgage Certificates still attached Mortgage rights for the Initial Creditors / Banks that are taken over. CCB Indonesia in approving the take over credit facility with the main consideration being that the debtor has a history of credit collectibility in the Debtor Information for the Financial Information Service System / IDEB SLIK OJK with current credit collectability. Debtors choose to take over credit facilities to CCB Indonesia because they obtain lower lending credit interest rates, higher credit facility ceilings, faster approval processes and credit decision making compared to Initial Creditors, free of administrative fees and free of notary fees. The main problem in this study is how to take over credit agreements with guaranteed mortgage rights at Bank China Construction Bank Indonesia Tbk. Pekanbaru Branch. How is the legal protection for the parties with a credit take-over agreement (take over) with guaranteed Mortgage Rights at Bank China Construction Bank Indonesia Tbk. Pekanbaru Branch. The method used in this research is empirical juridical research. Respondents / Informants as well as samples in this study are Credit Operations Head of "CCB Indonesia" Pekanbaru Branch of 1 (one) person and 7 (seven) Notary Partners of "CCB Indonesia" of Pekanbaru Branch. Data collection tool in this study was in the form of an interview. This research is descriptive in nature, providing complete and clear data on loan takeover agreements with guaranteed mortgage rights at Bank China Construction Bank Indonesia Tbk. Pekanbaru Branch. The results of the author's research indicate that the specificity of the credit take-over agreement (guarantee over) with guaranteed Mortgage in Article 3 explicitly specifies that currently the object of Mortgage Guarantee is still in the initial creditor / bank (taken over) and Article 4 expressly specifies that The debtor will transfer the funds to the initial creditor / bank account (taken over) from the proceeds from the disbursement of credit facilities obtained by the Debtor from the CCB Indonesia Pekanbaru Branch. After the signing of the credit agreement has been fulfilled, the Partner Notary issues a Cover Note / Certificate submitted to CCB Indonesia to continue the transfer of funds to the Debtor account at the Initial Creditors / Banks which are overtaken. Legal protection for the Parties in the Take Over Agreement with guaranteed Mortgage is carried out in 2 (two) forms, namely preventive and repressive from CCB Indonesia Creditor and Partner Notary.

Full textAbstract:
The author presents in this paper the new German foreign investment regime entered into force in the spring of 2009. He sets out the basic principles of the regime as well as its enforcement in practice. According to the new German foreign investment regime, the German Federal Ministry of Economics and Technology (BMWi) may examine and prohibit purchases of German companies by foreign investors if they pose a severe threat to public policy or security. Certain transactions, however, fall within the “safe harbour” or are otherwise exempted so that the BMWi has no right of interference. The author presents several exemptions from the scope of application of the regime, which can be either identified from the wording of the law by reverse argument or derived from the spirit and purpose of the new foreign investment regime. Furthermore, by presenting the concept of so called “critical infrastructures”, the paper gives valuable guidance to practitioners on what the German administration might consider relevant for public policy or security. The last part of the paper summarizes the filing and the review process. The parties may, in order to receive clearance for their transaction, notify their transactions to the BMWi and receive a certificate of non-objection. While, this notification is wholly voluntary, parties who do not apply for clearance bear the risk that their transactions are blocked or unwound if the BMWi decides to investigate the transaction within three months from signing ex officio.

Full textAbstract:
Fifth-generation (5G)-enabled vehicular fog computing technologies have always been at the forefront of innovation because they support smart transport like the sharing of traffic data and cooperative processing in the urban fabric. Nevertheless, the most important factors limiting progress are concerns over message protection and safety. To cope with these challenges, several scholars have proposed certificateless authentication schemes with pseudonyms and traceability. These schemes avoid complicated management of certificate and escrow of key in the public key infrastructure-based approaches in the identity-based approaches, respectively. Nevertheless, problems such as high communication costs, security holes, and computational complexity still exist. Therefore, this paper proposes an efficient certificateless authentication called the ECA-VFog scheme for fog computing with 5G-assisted vehicular systems. The proposed ECA-VFog scheme applied efficient operations based on elliptic curve cryptography that is supported by a fog server through a 5G-base station. This work conducts a safety analysis of the security designs to analysis the viability and value of the proposed ECA-VFog scheme. In the performance ovulation section, the computation costs for signing and verification process are 2.3539 ms and 1.5752 ms, respectively. While, the communication costs and energy consumption overhead of the ECA-VFog are 124 bytes and 25.610432 mJ, respectively. Moreover, comparing the ECA-VFog scheme to other existing schemes, the performance estimation reveals that it is more cost-effective with regard to computation cost, communication cost, and energy consumption.

Full textAbstract:
Abstract Certificateless public key cryptography (CL-PKC) promises a practical resolution in establishing practical schemes, since it addresses two fundamental issues, namely the necessity of requiring certificate managements in traditional public key infrastructure (PKI) and the key escrow problem in identity-based (ID-based) setting concurrently. Signcryption is an important primitive that provides the goals of both encryption and signature schemes as it is more efficient than encrypting and signing messages consecutively. Since the concept of certificateless signcryption (CL-SC) scheme was put forth by Barbosa and Farshim in 2008, many schemes have been proposed where most of them are provable in the random oracle model (ROM) and only a few number of them are provable in the standard model. Very recently, Luo and Wan (Wireless Personal Communication, 2018) proposed a very efficient CL-SC scheme in the standard model. Furthermore, they claimed that their scheme is not only more efficient than the previously proposed schemes in the standard model, but also it is the only scheme which benefits from known session-specific temporary information security (KSSTIS). Therefore, this scheme would indeed be very practical. The contributions of this paper are 2-fold. First, in contrast to the claim made by Luo and Wan, we show that unfortunately Luo and Wan made a significant error in the construction of their proposed scheme. While their main intention is indeed interesting and useful, the failure of their construction has indeed left a gap in the research literature. Hence, the second contribution of this paper is to fill this gap by proposing a CL-SC scheme with KSSTIS, which is provably secure in the standard model.

Full textAbstract:
Marriages are required to be registered under the provisions of Law Number 1 of 1974, specifically Article 2. This registration plays a crucial role in establishing the legality of marriages and enables the utilization of different associated benefits. Meanwhile, unregistered marriages give rise to a range of legal issues, including uncertainties regarding lineage, concerns related to maintenance, and inheritance rights. In line with the Ministry of Home Affairs Regulation Number 109 of 2019 regarding Population Administration, couples involved have the option to obtain important documents such as the Population Identification Card (KTP), Birth Certificate, and Family Card (KK) by signing a Statement of Absolute Responsibility (SPTJM). This situation raises significant concerns regarding the legal implications of unregistered marriages. Therefore, this study aimed to employ an empirical legal approach with qualitative methods and obtained data through interviews, observations, and documentation. The data analysis used Miles and Huberman's method to uncover the meaning within Ministry of Home Affairs Regulation Number 109 of 2019 regarding Unregistered Marriages and unveiled the ambiguity in understanding the true meaning. Furthermore, a study conducted in Dharmasraya Regency in 2021 discovered the issuance of 69,144 Family Cards by the Directorate General of Population and Civil Registration, and 22,453 (32.47%) were unregistered marriages. Only 194 individuals applied for validation (isbat) within 3 years, where 101, 27, and 66 were accepted, rejected, and revoked, respectively. In conclusion, the community perceived their marriages to be legal due to the issuance of Ministry of Home Affairs Regulation Number 109 of 2019, even though the SPTJM did not legalize the concept or hold legal authority over the consequences.

Taklik talak is the groom's divorce promise after signing the marriage contract. Taklik divorce is stated in the marriage certificate and is required for a specific event in the future. Seeing the habit of reading taklik talak in the Momunu sub-district, there are not a few cases of violations of taklik talak which are caused by the economy, domestic violence, extramarital affairs, and others, so there is no harmony in a household relationships. This study aimed to analyze the implementation of taklik divorce in Momunu district—research using qualitative methods. The data collection techniques are carried out through observation, interviews, and documentation. At the same time, data analysis is done by reducing, presenting, and verifying data. So that the data obtained has credibility and validity so that processing techniques and data analysis and checking the validity of the data are carried out. This study's results indicate two legal consequences from violations of taklik divorce in the sub-district of Momunu, namely the Khulu divorce lawsuit and the fulfillment of Iwadh Taklik Talak. After deeply analyzing the fatwa of the Indonesian Ulema Council, the authors conclude that the taklik divorce in marriage and its pronunciation has no urgency and is no longer relevant today. Regarding violations of taklik divorce committed by several parties, the wife may impose divorce because the husband has left or the husband's whereabouts are unclear. According to the Malik school of thought, taklik divorce is considered divorce ba'in, while according to the Ahmad school of thought, it is fasakh. This is to prevent harm to the woman. The wife may also ask for a divorce if the husband leaves her.

Full textAbstract:
This research aims to know and analyze the role of land deed officials in making the deed of transfer of land rights and registration of transfer of names during the covid-19 pandemic at the Pekalongan City Land Office, to find out and analyze the legal consequences of making a deed of transfer of land rights that have been transferred, and to find out and analyze examples of a deed of transfer of land rights. This study uses a sociological juridical approach. This research specification uses descriptive analysis. The types and sources of data used in this study are primary data from interviews, while secondary data is obtained through library research. Research data collection is divided into 2 (two), namely primary data collection is done by interview and secondary data collection is done by collecting data contained in laws and regulations, books, articles and others. The data analysis method used in analyzing the data is qualitative analysis. The results of the study indicate that the role of PPAT is to carry out some of the tasks of the state in the land sector, as a public official who is authorized to make authentic deeds. Since the signing of the deed by the parties, PPAT as one of the implementing officials of land registration is obliged to submit the deed he made and register the name transfer at the local Land Office. Since the Covid-19 pandemic, the Pekalongan City Land Office has implemented 8 (eight) steps of the conventional or semi-online service process, this is done so that services continue to run in a conducive manner and prevent the spread of the covid-19 outbreak. Second, there is legal certainty and legal protection for new rights holders by making a deed of transfer of land rights which has been transferred to a certificate of land rights.

Penelitian ini membahas mengenaiadanya pendaftaran akta PPAT ke kantor Pertanahan (BPN) yang melebihi dari 7 (tujuh) hari kerja setelah penandatanganan di kantor PPAT yang di daftarkan ke Kantor Pertanahan (BPN) Kabupaten Ponorogo oleh PPAT tersebut. Sedangkan jelas pada Pasal 40 ayat (1)PP 24/1997 tentang PendaftaranTanah menegaskan bahwa: “selambat-lambatnya 7 (tujuh) hari kerja sejak tanggalditandatanganinya akta yang bersangkutan, PPAT wajibmenyampaikan akta yang dibuatnya berikut dokumen-dokumenyang bersangkutan kepada Kantor Pertanahan (BPN) Kabupaten/Kota setempat sessuai wilayah kerja PPAT yang bersangkutan untuk didaftar’. Berdasarkan hasil penelitian yang dilakukan, bahwa terdapat beberapafaktor penghambat dalam penyampaian pendaftaran hak atas tanah oleh PPAT ke Kantor Pertanahan Kabupaten Ponorogo yaitu: 1. Kurangnya penyampaian berkas-berkas yang disampaikan klien kepada PPAT. Seperti: Sertipikat asli; Foto kopi KTP dan KK pihak penjual, apabila tanah tersebut merupakan harta bersama dengan istrinya maka dilampirkan pula foto kopi KTP istri dan foto kopi surat nikah; Foto kopi KTP dan KK pihak pembeli; Foto kopi Surat Pemberitahuan Pajak Terutang Pajak Bumi dan Bangunan (SPPT PBB) 5 (lima) tahun terakhir dan tahun berjalan/tahun terakhir, belum e-KTP; 2. Adanya suatu situasi yang mengharuskan PPAT terlambat mendaftarkan akta jual belinya dikarenakan ada hal yang harus dilakukan guna untuk menyelamatkan suatu transaksi jual beli. Pembuatan akta jual beli seperti ini terlihat dalam konstruksi transaksi jual beli dimana pajak-pajak terutang yang telah dibayar belum tervalidasi baik pajak pembeli (BPHTB) maupun pajak penjual (SSP PPh Final) pada saat penandatanganan akta dilakukan. 3. Terdapat rasa saling percaya yang sangat tinggi di antara sesama PPAT dan antara para pihak dengan PPATdan tidak akan terdapat masalah di kemudian hari yang dapat menyulitkan mereka. 4.Faktor waktu dan kesibukan dari PPAT, sehingga menyebabkan PPAT tidak bisa mendaftarkan kewajibannya untuk mendaftarkan aktanya sebelum 7 hari kerja setelah penandatanganan akta PPAT tersebut.Implikasi hukum terkait dengan tindakan PPAT yang tidak melaksanakan kewajiban menyampaikan berkas pendaftaran tanah sebelum 7 (tujuh) hari kerja setelah penandatanganan ke Kantor Pertanahan Kabupaten Ponorogo adalah dengan cara mengukur sejauh mana ketentuan itu ditaati atau tidak ditaati oleh subyek hukumnya, dalam hal ini adalah PPAT. Terkait dengan hal tersebut, belum adanya hukum yang mengatur dengan tegas tentang sanksi bagi PPAT tersebut dari konsep struktur hukum. Tindakan hukum terhadap pendaftaran tanah yang didaftarkan oleh PPAT ke kantor Pertanahan (BPN) Kabupaten Ponorogo yang melebihi jangka waktu 7 (tujuh) hari, yaitu hanya dikenai teguran lisan dan teguran tertulis yang disampaikan kepada PPAT bersangkutan dan kepada organisasi IPPAT, sedangkan untuk pendaftaran hak atas tanah tetap diproses oleh Kantor Pertanahan.Kata Kunci: Pendaftaran Tanah, PPAT, Sanksi This research discusses the existence of Land Deed Maker Officer (PPAT) deed registration to the Land Office (BPN) which is more than 7 (seven) working days after the signing at the Land Deed Maker Officer (PPAT) office which is registered with the Ponorogo Regency Land Office (BPN) by the Land Deed Maker Officer (PPAT). Meanwhile, it is clear in Article 40 paragraph (1) PP 24/1997 concerning Land Registration that: "no later than 7 (seven) working days from the signing date of the deed concerned, Land Deed Maker Officer (PPAT) is obliged to submit the deed made along with the relevant documents to the Office. Local Regency / City Land(BPN) in accordance with the Land Deed Maker Officer (PPAT) working area concerned to be registered '. Based on the results of the research conducted, there are several inhibiting factors in submitting registration of land rights by Land Deed Maker Officer (PPAT)to the Ponorogo Regency Land Office, namely: 1. Lack of submission of files submitted by clients to Land Deed Maker Officer (PPAT). Such as: original certificate; A photocopy of the seller's identy card population (KTP) and family card (KK), if the land is joint property with his wife, then a copy of the wife's identy card population (KTP) and a copy of the marriage certificate shall also be attached; Photocopy of the buyer's identy card population (KTP) and family card (KK); Photocopy of Land and Building Tax Payable Tax Return (SPPT PBB) for the last 5 (five) years and current / last year, not yet electronic identy card population (e-KTP); 2. There is a situation that requires Land Deed Maker Officer (PPAT) to be late in registering its sale and purchase deed because there are things that must be done in order to save a sale and purchase transaction. The making of a sale and purchase deed like this can be seen in the construction of a sale and purchase transaction where the payable taxes that have been paid have not been validated, either the buyer tax (BPHTB) or the seller tax (SSP PPh Final) at the time the deed is signed. 3. There is a very high sense of mutual trust between Land Deed Maker Officer (PPAT) and between the parties and Land Deed Maker Officer (PPAT) and there will be no problems in the future that could make it difficult for them. 4. The time factor and the busyness of the Land Deed Maker Officer (PPAT), thus causing Land Deed Maker Officer (PPAT) to be unable to register its obligation to register its deed before 7 working days after signing the Land Deed Maker Officer (PPAT) deed. The legal implication related to Land Deed Maker Officer (PPAT) friends action that does not carry out the obligation to submit land registration documents before 7 (seven) working days after signing to the Ponorogo Regency Land Office is by measuring the extent to which the provisions are adhered to or not obeyed by its legal subjects, in this case Land Deed Maker Officer (PPAT). In this regard, there is no law that clearly regulates the sanctions for Land Deed Maker Officer (PPAT) from the concept of a legal structure. Legal action against land registration registered by Land Deed Maker Officer (PPAT) at the Ponorogo Regency Land Office (BPN) which exceeds a period of 7 (seven) days is only subject to verbal and written warnings submitted to the relevant Land Deed Maker Officer (PPAT) and to the Land Deed Maker Officer Unity (IPPAT) organization, while registration of rights to land is still being processed by the Land Office.Keywords: Land Registration, Land Deed Maker Officer (PPAT), Sanctions

Full textAbstract:
We present a quantum scheme for signing contracts between two clients (Alice and Bob) using entangled states and the services of a third trusted party (Trent). The trusted party is only contacted for the initialization of the protocol, and possibly at the end, to verify clients’ honesty and deliver signed certificates. The protocol is fair, i.e., the probability that a client, say Bob, can obtain a signed copy of the contract, while Alice cannot, can be made arbitrarily small, and scales as N − 1 / 2 , where 4 N is the total number of rounds (communications between the two clients) of the protocol. Thus, the protocol is optimistic, as cheating is not successful, and the clients rarely have to contact Trent to confirm their honesty by delivering the actual signed certificates of the contract. Unlike the previous protocol (Paunković et al., Phys. Rev. A 84, 062331 (2011)), in the present proposal, a single client can obtain the signed contract alone, without the need for the other client’s presence. When first contacting Trent, the clients do not have to agree upon a definitive contract. Moreover, even upon terminating the protocol, the clients do not reveal the actual contract to Trent. Finally, the protocol is based on the laws of physics, rather than on mathematical conjectures and the exchange of a large number of signed authenticated messages during the actual contract signing process. Therefore, it is abuse-free, as Alice and Bob cannot prove they are involved in the contract signing process.

Full textAbstract:
IoT devices provide real-time data to a rich ecosystem of services and applications. The volume of data and the involved subscribe/notify signaling will likely become a challenge also for access and core networks. To alleviate the core of the network, other technologies like fog computing can be used. On the security side, designers of IoT low-cost devices and applications often reuse old versions of development frameworks and software components that contain vulnerabilities. Many server applications today are designed using microservice architectures where components are easier to update. Thus, IoT can benefit from deploying microservices in the fog as it offers the required flexibility for the main players of ubiquitous computing: nomadic users. In such deployments, IoT devices need the dynamic instantiation of microservices. IoT microservices require certificates so they can be accessed securely. Thus, every microservice instance may require a newly-created domain name and a certificate. The DNS-based Authentication of Named Entities (DANE) extension to Domain Name System Security Extensions (DNSSEC) allows linking a certificate to a given domain name. Thus, the combination of DNSSEC and DANE provides microservices’ clients with secure information regarding the domain name, IP address, and server certificate of a given microservice. However, IoT microservices may be short-lived since devices can move from one local fog to another, forcing DNSSEC servers to sign zones whenever new changes occur. Considering DNSSEC and DANE were designed to cope with static services, coping with IoT dynamic microservice instantiation can throttle the scalability in the fog. To overcome this limitation, this article proposes a solution that modifies the DNSSEC/DANE signature mechanism using chameleon signatures and defining a new soft delegation scheme. Chameleon signatures are signatures computed over a chameleon hash, which have a property: a secret trapdoor function can be used to compute collisions to the hash. Since the hash is maintained, the signature does not have to be computed again. In the soft delegation schema, DNS servers obtain a trapdoor that allows performing changes in a constrained zone without affecting normal DNS operation. In this way, a server can receive this soft delegation and modify the DNS zone to cope with frequent changes such as microservice dynamic instantiation. Changes in the soft delegated zone are much faster and do not require the intervention of the DNS primary servers of the zone.

<p>Sengketa pemilihan umum presiden 2014 telah mendatangkan ribuan kotak suara ke Jakarta sebagai bukti hukum. Gambar-gambar form C1 yang merupakan salinan rekapitulasi hasil di TPS yang sudah diunggah di situs web KPU, ternyata tidak dapat dijadikan sebagai bukti hukum karena tidak bisa dibuktikan keabsahannya sebagai dokumen elektronik. Tanda tangan digital merupakan bukti otentik yang terdapat pada dokumen elektronik. Penggunaan tanda tangan digital dapat memastikan keutuhan dan keaslian suatu dokumen elektronik sehingga dapat dipertanggungjawabkan secara hukum. Hal ini menjadi salah satu alasan dilakukannya penerapan tanda tangan digital pada formulir model C1.PLANO-KWK. Formulir ini merupakan berita acara hasil pemungutan dan penghitungan suara pemilihan umum di tempat pemungutan suara. Formulir tersebut diambil gambarnya menggunakan aplikasi berbasis ponsel Android untuk kemudian ditandatangani secara digital.

Abstract: With technological advancements along with tremendous generation and storage of sensitive data, which can be cryptographic keys, passwords or other data that can be crucial for operation of an organization, thereis a need to secure this sensitive data startingfrom its creation, its transfer from one place to another and its final place of storage. Thiscan be done with the help of cryptography and cryptographic algorithms that can help secure this entire process. With cryptography, it is possible to securely transfer sensitive data to ensure that it cannot be read or tampered by a third party. Cryptography and its related algorithms can also be used to secure the network for safe transfer and storage of sensitive data. In this paper, starting with a brief introduction to cryptography concepts and some networkingprotocols, we shall discuss and compare usage of an algorithm such as AES, hashing and importance of Digital Certificates and Signing operation along with encryption for better security.

Full textAbstract:
The emergence of electronic certificates, which are official documents in the form of digital files transmitted via the internet, facilitates the exchange of information. However, internet use has risks, such as data theft for fabricating and modifying information. This problem can be solved by applying a digital signature. This problem can be solved by applying a digital signature. The main concern in this research is how to perform a comparative analysis between asymmetric cryptographic Elgamal and NTRU (Nth-Degree Truncated Polynomial Ring) algorithms and their implementation of a digital signature as an effort to improve information security in electronic certificates. The stages of the research method are divided into the key generation process, signing, and verification. In the signing and verification process, the SHA-512 hash function is also used for hashing messages to be encrypted-decrypted and QR Code as the signature. Comparison of performance of NTRU with Elgamal algorithms required running at a pdf extension with security levels 80,128,192, 256 bits will be obtained from the templates.office.com website. The results obtained that the El Gamal algorithm is better than the NTRU algorithm, but at a higher security level, the NTRU algorithm is better than the Elgamal algorithm. In the verification experiment that has been carried out, it can be concluded that by using SHA-512 as a hash function, the N parameter used for NTRU must be greater than or equal to 512 to avoid error results from verification.
