Abstract:
Seiring dengan perkembangannya, teknologi data dalam bentuk file terus berkembang dan mengalami peningkatan ukuran dari waktu ke waktu. Perkembangan teknologi yang semakin maju dengan penambahan jumlah pengguna komputer yang semakin banyak menyebabkan ledakan jumlah data serta tingkat perpindahan data dari satu perangkat ke perangkat lain. Data - data tersebut umumnya dikompresi terlebih dahulu agar proses pertukaran data tidak memakan waktu yang terlalu lama. Metode yang akan digunakan pada penelitian ini adalah algoritma Huffman Encoding dan konversi Biner Hexadecimal. algoritma Huffman Encoding adalah salah satu algoritma kompresi dengan cara melakukan pengkodean dalam bentuk bit untuk mewakili data karakter, sedangkan konversi Biner Hexadecimal adalah teknik untuk mengubah rangkaian bit yang akan dikonversi menjadi bilangan hexadecimal. Hasil dari penelitian ini adalah algoritma Huffman Encoding dan konversi Biner Hexadecimal dapat diimplementasikan untuk kompresi file. Simpulan dari aplikasi ini yaitu metode Huffman Encoding dan konversi Biner Hexadecimal dapat melakukan mengkompresi dengan baik pada 26 macam ekstensi file akan tetapi, metode ini tidak lebih baik dibandingkan program kompresi WinRAR dan WinZIP. Ini telah dibuktikan dengan pengujian keterbatasan dan peforma program terhadap 50 jenis file yang berbeda.

Abstract:
In this paper, a novel image steganography approach is proposed to enhance the visual quality of stego image. The cover image is decomposed using Discrete Wavelet Transform (DWT) to produce wavelet subbands and threshold value is calculated for each higher frequency wavelet subbands. Wavelet coefficients having magnitude larger than the threshold of its subband are selected to embed the secret data. Semi Hexadecimal Code (SHC) is proposed to convert pixel value of secret image into smaller equivalent value so that it distorts stego image as less as possible. Experimental results shows that maximum PSNR between cover image and stego image is more than 75 dB .Proposed approach is also compared with the existing approaches and this comparison shows that the proposed approach is better than the existing approaches.

Abstract:
In order to enhance the operation efficiency of RSA algorithm, a new improved algorithm was suggested in this paper which made some improvements in structure and operation, and it was applied to digital signature. The experiment made comparison between a combinatorial optimization algorithm which combined SMM with index of 2k hexadecimal algorithm and the new algorithm. It shows that the new algorithm reaches a high level in operation speed.

Abstract:
Al-Quran is the holy book of the Muslims and the most important scripture containing knowledge on many domains. The recent advent of smart technologies like smart phones, digital devices and tablets has connected the daily life routines under a single touch adopted by many, these new tools with an exponential growth. This paper presented a Digital Quran Model (DQM) using hexadecimal representation using Unicode Hexadecimal and UTF-8 for character encoding, which is backward compatible with ASCII code. DQM target to handle all duplicated words or verses in Al-Quran using sparse matrix with double offset indexing to handle memory optimization. Three approaches were discussed: indexing and representation of the digital Quran to optimize storage, organize verses structure using sparse matrix to handle repetition with double offset indexing to efficiently use the space. The algorithms were implemented using Visual studio and Java server and the solution quality was measured by the size of a file before and after applying DQM model. For surah Al-Baqarah, the longest chapter in the Al-Quran, the reduction of the storage size was 25.00% whereas surah Al-Fatihah was 47.89%. The proposed DQM model is able to optimize the memory space and can be extended to other non-Roman characters used for information retrieval such as Hindi, Chinese and Japanese that are categorized in unicode standards.

Abstract:
RFID-kort har ett utbrett användningsområde i dagens samhälle för bland annat passage, resekort och pass. RFID-kort av märket MIFARE Classic har i tidigare arbeten visats innehålla säkerhetsbrister. Detta undersöks för att se hur situationen ser ut idag med fokus på RFID-kort som attackvektor och i jämförelse med tidigare arbeten. Användandet av RFID-kort som attackvektor har i utförandet av experimenten visats fortfarande vara möjligt och även betydligt mindre begränsat. Där lagringskapacitet och användningsområde tidigare begränsat skadan man kan åstadkomma med RFID-kort, har nu standarden ökat och med det även lagringskapaciteten att skapa elak-artad kod. Med hjälp av en Arduino och en mobiltelefon är det möjligt att kopiera information från RFID-kort som till exempel lokaltrafikens resekort till ett mycket mindre säkert RFID-kort i ont syfte. Diskussionen tar upp möjligheterna att genom korsreferensering identifiera specifik information från varje kort, samt huruvida mer avancerade attacker som ransomware är applicerbara eller ej. Vidare utforskas även hur möjligheterna ser ut att lägga till egen kod och ser även där farhågor i användandet av RFID-kort utan ytterligare säkerhets-lager.

Abstract:
Binary can be challenging. The values tend to have a lot of digits, long sequences of ones or zeros can be difficult to distinguish, and the relative magnitudes of multiple binary values can be difficult to resolve. In this episode, we discuss a couple of the popular methods to quickly represent binary in a more human readable form.

Abstract:
Field Programmable Gate Arrays (FPGAs) are increasingly being used for high-throughput floating-point computation. It is forecasted that by 2009, FPGAs will provide an order of magnitude greater sustained floating-point throughput than conventional processors. FPGA implementations of floating-point operators have historically been designed to use binary floating-point representations, as do general purpose processors. Binary representations were chosen as the standard over three decades ago because they provide maximal numerical accuracy per bit of floating-point data. However, the unique nature of FPGA-based computation makes numerical accuracy per unit of FPGA resources a more important measure of the usefulness of a given floating-point representation. From this viewpoint, higher radix floating-point representations are well suited to FPGA-based computations, especially high precision calculations which require the support of denormalized numbers. This work shows that higher radix representations lead to more efficient use of FPGA resources. For example, a hexadecimal floating-point adder provides a 30% lower Area-Time product than its binary counterpart, and a hexadecimal floating-point multiplier has a 13% lower Area-Time product than its binary counterpart. This savings occurs while still delivering equal worst-case and better average-case numerical accuracy. This work presents a family of higher radix floating-point representations that are designed specifically to interoperate with standard IEEE floating-point, allowing the creation of floating-point datapaths which operate on standard binary floating-point data, yet use higher radix representations internally. Such datapaths provide higher performance by any measure: they are more accurate numerically, consume less FPGA resources and have shorter latencies. When taking into consideration the unique nature of FPGA-based computing systems, this work shows that binary floating-point representations are not optimal for most FPGA-based arithmetic computations. Higher radix representations can therefore be a useful tool for building efficient custom floating-point datapaths on FPGAs.
