Résumé :
Designing a secured voice transmission system is not a trivial task. Wired media, thanks to their reliability and resistance to mechanical damage, seem an ideal solution. The BPL (Broadband over Power Line) cable is resistant to electricity stoppage and partial damage of phase conductors, ensuring continuity of transmission in case of an emergency. It seems an appropriate tool for delivering critical data, mostly clear and understandable voice messages. This paper describes such a system that was designed and evaluated in real-time operating conditions. It involved a two-way transmission of speech samples in American English and Polish. The efficiency of the designed solution was evaluated in the subjective study on a group of 15 people.

Résumé :
Mobile nodes roaming around in the hostile environment of mobile adhoc network (MANET) play the role of router as well as terminal. While acting as a router, a node needs to choose a reliable routing protocol. Besides, an encryption algorithm is needed to secure data to be conveyed through the unfriendly atmosphere while acting as a terminal. We have implemented Elliptic Curve Cryptography (ECC) along with Adhoc On Demand Multipath Distance Vector (AOMDV) routing protocol to secure data transmission against blackhole attack in a MANET. ECC, a public key cryptography that works on discrete logarithm problem with a much smaller key size, has been used to encrypt data packets at source node before transmission. We have used AOMDV, a reliable routing protocol compared to its parent protocol, Adhoc On Demand Distance Vector (AODV), with a multipath extension, for routing. The encrypted packets transferring between nodes via AOMDV, has been proved secured against blackhole attack. The performance of the secured protocol has been analyzed in terms of different performance metrics and in terms of varying number of blackhole attacker nodes.

Résumé :
The Internet of Things (IoT) has changed the world into a more physically connected, ensuring higher order applications. As smart devices and patients surrounding are able to freely communicate with each other, more chances and conveniences are brought to us. However, as the information is kept inside these devices is revealed and distributed, security and privacy concerns call for an effective safeguarding process more than ever. Secured data transmission with higher voluminous data indulging with noisy instances, the computational cost and overhead incurred remains the major issues for IoT based health care system. The complexity of the inferred model may increase, and thereby the overall secured data transmission accuracy of the model may decrease. In this work, the above said issues are addressed via secure data transmission method, in order to minimize the computational cost and overhead incurred during transmission of large data and also improve the data transmission accuracy with minimum running time. The method is called as Delay-aware and Energy-efficient Laplace Angular Displacement (DE-LAD). The DE-LAD method involves three steps. They are data collection, data communication and data transmission. First data collection is performed via delayaware and energy-efficient model. Second data communication is said to be established using pairing-free Laplace Estimator, minimizing computational complexity involved during data collection. Finally, secured data transmission is achieved via Angular Displacement. Moreover, in WSN, the security of data being transmitted is calculated for IoT-based healthcare system. The simulation results of DE-LAD method provides enhanced performance in terms of security and complexity as compared to conventional methods.

Résumé :
Wireless Sensor Network (WSN) need to be more secure while transmitting data as well as should be deployed properly to reduce redundancy and energy consumption. WSNs suffer from many constraints, including low computation capability, small memory, limited energy resources, susceptibility to physical capture and the use of insecure wireless communication channels. These constraints make security in WSNs a challenge. In this paper, a survey of security issues in WSNs is presented and a new algorithm TESDA is proposed, which is an optimized energy efficient secured data aggregation technic. The cluster head is rotated based on residual energy after each round of aggregation so that network lifetime increases. Based on deviation factor calculated, the trust weight is assigned, if more deviation, then the trust value is less. Simulation results observed by using NS-2. From network animator and x-graphs the result are analyzed. Among all protocols tesda is an energy efficient secured data aggregation method.

Résumé :
In secure communication key management plays an important role. Ensuring of security and trust worthiness in any transmission taking place via Wireless Sensor Networks (WSN) can be done using thoughtfully designed key management models. Here, the method of clustering is used to increase the system performance. Also, an effective key generation method is proposed for secured data transmission for the clustered wireless sensor networks. This method uses Chinese Remainder Theorem (CRT) for generating secret key for each cluster and merges with cluster head ID to generate a unique 144-bit encryption keys. Since, CRT uses random numbers for generating keys, separate active keys that are dynamic to ensure secured data transmission. The proposed model provides a positive impact by improving the lifetime, reducing the delay time, memory requirements and energy consumption, when compared with other existing state of art methods. Moreover, it protects data from brute-force attack, forward as well as backward secrecy and node compromised attack.

<p>The performance of the Wireless sensor networks (WSNs) identified as the efficient energy utilization and enhanced network lifetime. The multi-hop path routing techniques in WSNs have been observed that the applications with the data transmission within the cluster head and the base station, so that the intra-cluster transmission has been involved for improving the quality of service. This paper proposes a novel Hybrid Energy-based Secured Clustering (HESC) technique for providing the data transmission technique for WSNs to produce the solution for the energy and security problem for cluster based data transmission. The proposed technique involves the formation of clusters to perform the organization of sensor nodes with the multi-hop data transmission technique for finding the specific node to deliver the data packets to the cluster head node and the secured transmission technique is used to provide the privacy of the sensor nodes through the cluster. The residual energy of the sensor nodes is another parameter to select the forwarding node. The simulation results can show the efficiency of this proposed technique in spite of lifetime within the huge amount data packets. The security of this proposed technique is measured and increases the performance of the proposed technique.</p> <p>&nbsp;</p>

Résumé :
<span>Transmission control protocol provides reliable communication between two or more parties. Each transmitted packet is acknowledged to make sure successful deliveries. Transport layer security protocols send security information exchange as TCP loads. As results, the handshaking stage experiences longer delay as TCP acknowledgement process has already been delay prone. Furthermore, the security message transfers may have their own risks as they are not well protected yet. This paper proposes TCP-embedded three pass protocol for dynamic key exchange. The key exchange is embedded into TCP headers so that transmission delay is reduced, and message transfer is secured. The proposed protocol was assessed on self network by using socket programming in lossless environment. The assessments showed that the proposed protocol reduced three-pass protocol message transfer delay up to 25.8% on lossless channel. The assessment on security also showed that TCP-embedded three pass protocol successfully secured each transmitted TCP load using a unique key; that is much securer than the compared method.</span>

Résumé :
As a result of advancements in technology areas including mobile communication, semiconductors, and 5G internet, things have changed very quickly.Near field communication [NFC] has gained popularity due simplicity in use and function. Given that the weaknesses in the current technique were discovered, this paper proposed a new protocol for more secure NFC payments and data transfer. And thus conducted a thorough analysis of NFC payments and discovered that the data carried over the air was weak and easily intercepted by using tools like as Pflipper zero, Hackrf-one, and RTL-SRD, and later could be decoded utilising cutting-edge computations and GNU. This suggested protocol entails local-level verification for the creation of a transmission channel between a card and a Point of Sale [POS] at the local-level, allowing a secured point-to-point connection between the two end points. In addition to the first step indicated, the channel will make sure that no data is being eavesdropped by an unauthorised devices or antenna. If so, both the channel and any data that was transmitted over it are immediately destroyed. This protocol would offer more security declarations and aid by making payments secured, safe, and morally correct.

Résumé :
Wireless medical sensor network is used in healthcare applications that have the collections of biosensors connected to a human body or emergency care unit to monitor the patient's physiological vital status. The real-time medical data collected using wearable medical sensors are transmitted to a diagnostic centre. The data generated from the sensors are aggregated at this centre and transmitted further to the doctor's personal digital assistant for diagnosis. The unauthorised access of one's health data may lead to misuse and legal complications while unreliable data transmission or storage may lead to life threatening risk to patients. So, this system uses Advanced Encryption Standard (AES) algorithm to encrypt the data to make it secured transmission and access control system for medical sensor network. Further the data is sent to a centralised server through a wireless network. In this case this server can be a Personal Computer (PC) connected to the same network, for this transmission User Datagram Protocol (UDP) can be used. This data can be accessed at the receiver side only.

Augmentation in communication and coding technology has made encryption an integral part of secure multimedia communication systems. Security solution for end-to-end image transmission requires content adaptation at intermediate nodes, which consumes significant resources to decrypt, process, and reencrypt the secured data. To save the computational resources, this paper proposes a network-friendly encryption technique, which can be implemented in transparency to content adaptation techniques. The proposed encryption technique maintains the compression efficiency of underlying entropy coder, and enables the processing of encrypted data. Thorough analysis of the technique, as regards various standard evaluation parameters and attack scenarios, demonstrates its ability to withstand known-plaintext, ciphertext-only, and approximation attacks. This justifies its implementation for secure image transmission for end-to-end communication systems.

Steganography and cryptographic methods are used together with wavelets to increase the security of the data while transmitting through networks. Another technology, the digital watermarking is the process of embedding information into a digital (image) signal. Before embedding the plain text into the image, the plain text is encrypted by using Data Encryption Standard (DES) algorithm. The encrypted text is embedded into the LL subband of the wavelet decomposed image using Least Significant Bit (LSB) method. Then the inverse wavelet transform is applied and the resultant image is transmitted to the receiver. The receiver will perform the same operations in reverse order.

Résumé :
We have considered the problem of secure communication by means of chaotic carrier communication channels. Data protection is provided if the signal in the communication channel looks like a stochastic or noisy one, i.e., by the steganography property, and also by using advanced and secured approaches of mixing a useful signal into a chaotic carrier. The problem is to find effective and efficient techniques for useful signal reconstruction at the receiver side. We firstly use a synergetic nonlinear mathematical observer to recover the two useful signals transmitted simultaneously over a single communication channel. Compared to a known observer, the synergetic one operates with initial nonlinear models, i.e., it may be applied directly to chaotic systems. In that system structure, we consider the useful signals as unobservable variables and estimate them by the given model of a chaotic generator. A chaotic data transmission system with two channels is demonstrated; the presented mathematical procedure explains the steps of synergetic two-channel observer design. Computer simulation results prove the viability of our approach. The proposed data transmission scheme and the observer design procedure provide effective transmission and reconstruction of informational signals. Reconstruction error is up to approximately 25% but has a very short pulses shape and could be eliminated with further analog or digital filtering algorithms. As an example application, simulation of image transmission and recovery is demonstrated. The study’s results may be used as a basis for further research into secure data transmission system design.

Résumé :
In the current era of smart homes and smart grids, complex technical systems that allow for the automation of domestic functions are rapidly growing and becoming more widely available. A wide range of technologies and software applications are now available for use in smart homes, and many of them are free to use. They allow for communication between home appliances and their users, as well as the automation, monitoring, and remote-control capabilities of home appliances themselves. Unfortunately, a lot of previous research ignored security issues involving the great attention to detail of the data in a transmission session within the devices in smart home architectures, which is why this study proposed smart grid secured transmission flags suitable for preventing every bit of data transmission in a smart home. Secure Message Queueing Transport Protocol (MQTT) in Internet of Things (IoT) Smart Homes protocols was utilized; an experimental testbed was designed with a prototype involving the process of a smart home system and the sequences of the data transmission. The evaluation of the proposed strategies has shown an improved bi-directional secure resource constraint strategy for the smart home within data packet transmission at 70 to 80 mbps over secure MQTT. A number of concerns, including technological barriers, difficulties, challenges, and future trends, as well as the role of users, have been presented in this study, among others.

Résumé :
Currently there is no method, feature, or ability in securing data transmission in microcontroller systems and applications with client-server scheme communication, while major modern computer systems using secure socket layer (SSL) for establishing secure communication. However, ESP espressif based microcontroller has supported SSL communication to secure data transmission, but only works on the Wi-Fi network. A single-board computer based embedded system has fully supported SSL communication, but it costs a very high price. On the other hand, STM32F103 microcontrollers with a very affordable price even cheaper than the Arduino board has the opportunity to build secure data communication using SSL protocol based on MbedTLS library. In addition to wiznet W5100/W5500 ethernet shield, an STM32F103 SSL client device has been successfully built in this study. The SSL client device supports ECDHE ECDHA AES128 CBC SHA256 SSL cipher suite. The Apache web server must also be configured to support this cipher suite by generating OpenSSL ECC (elliptic curve cryptography) certificate. The system was tested with the LM35 analog temperature sensor, and as a result, the STM32F103 SSL client has successfully secured the data transmission to the Apache SSL web server. The communication time was 3 seconds for the first connection and 42 ms for the next data transmission.

Résumé :
Due to the increased development in technique of data transfer over internet and transmission media, the access and copy to these data in unathentical manner became a big challenge in the transmission media. This challenge led to make effort in digital multimedia security. In this paper a new algorithm is proposed to protect image from unauthentication access using watermarking. The watermarking algorithm hide the mark image in frequency domain using Discrete Cosine Transform and extract it at the receiver from the transmitted image without need for origin image. The basic principle of the algorithm is depend on spread spectrum communications. The spread spectrum depend on transmit a narrow band signal over a much larger bandwidth where that the signal energy is undetectable. Similarly, the watermark image bits are spread by a large factor called chip-rate so that it is imperceptible and arrange in cover image in away where if the half of the watermarked image is cropped, the watermark image is not affected. The proposed algorithm efficiency is measured by using many of measurement factors such as Peak Signal to Noise Ratio PSNR and Normalized Correlation Coefficient NC, the watermark robustness and feasibility are measured by using many types of attacks.

Résumé :
At present scenario, sensor devices are used in various fields for gathering information so all those data should be secured safely. Securing data is an important role in Wireless Sensor Networks (WSN). WSN is extremely essential for the purpose of reducing the complete redundancy and energy consumption during gathering data among sensor nodes. Optimized data aggregation is needed at cluster head and Base Station (BS) for secured data transmission. Data aggregation is performed in all routers while forwarding data from source to destination node. The complete life time of sensor networks is reducing because of using energy inefficient nodes for the purpose of aggregation. So this paper introduces the optimized methods for securing data (OMSD) which is trust based weights and also completely about the attacks and some methods for secured data transmission.

Résumé :
Vehicular Adhoc Network (VANET) is becoming a fundamental important component of Intelligent Transport System (ITS). VANET is one of the evolutionary network for providing safety related services, management of traffic and other user related services. VANET communication involves either Vehicle to Infrastructure (V2I) or Vehicle to Vehicle (V2V). In the current scenario, Multi-hop Authenticated Proxy Mobile IP (MA-PMIP) scheme is used in VANET where only 3G networks is considered and the scheme is unable to support transmission of substantial massive data while maintaining the security. The performance of MAPMIP drastically degrades during transmission of huge volume of data which leads to huge power dissipation. To overcome these problems a novel Fuzzy logic Based Secured Routing (FBSR) mechanism is proposed. The FBSR prevents Sink hole attack and Sybil attack. In order to avoid collision during large file transfer, TDMA and multi-threading concepts are introduced in FBSR. Furthermore, the performance of FBSR is compared with contemporary routing protocols OLSR and AODV.

Résumé :
The efficiency of selecting the cluster head plays a major role in resolving the complexities faced in network management aiming to improve the longevity of sensors in the network. The clustering process is followed by selecting proper cluster heads with the consideration of energy conservation among participant nodes. While coming to security concept on WSN, the trust based cluster head selection is significant with the assumption of cooperation of all sensor nodes. In view of this assumption, the traditional methods could not help in defining the ideal cluster head of the network. This work proposes Voronoi Clustered Secure Contextual Cryptographic Algorithm (VC-SCCA) by combining Voronoi method for clustering process and cryptographic algorithm for secure data transmission. This is considered as two-tier architecture whereas, clustering takes place in first tier and encryption along with decryption takes place in the second tier. The proposed algorithm is compared with two state-of-art methods such as, Secured WSN (SeC‐WSN) and Taylor based Cat Salp Swarm Algorithm (Taylor C-SSA) in terms of energy consumption, Packet Delivery Ratio (PDR), network lifetime, encryption time and decryption time. As a result, the proposed VC-SCCA achieves 53.2% of energy consumption, 98.6% of packet delivery ratio, 97.5% of network lifetime, 62.8sec of encryption time and 71.2sec decryption time.
