hash algorithms have been widely used for cryptography. It has been impossible to decrypt the ciphertexts generated through hash algorithms, as an operation that damages the original text is performed. The vulnerability of SHA1 (an old hash algorithm) has been revealed, and there has been a great deal of data available for dictionary attacks. Although the industry has been gradually refraining from using SHA1, it remains in use in some existing systems for various reasons. In particular, when problems resulting from medical service interruption or mass update are directly related to a person's life, updating the encryption algorithm can be a burden. In this study, we aim to increase the complexity of ciphertexts by postprocessing hash ciphertext by masking message digest to a two-dimensional array constructed using an image processing technique. This will allow the use of hash ciphertexts with increased complexity in some medical devices that are forced to use old hash algorithms for various reasons.

This paper is about a proposal of the algorithm to derive encryption keys based on key-files using the hash algorithm SHA-3. For our upcoming design of block cipher with special key length, which is 111 bytes, we are facing the problem how to derive encryption keys, even there are for example scrypt or Argon2 key-derivation function, we would like to design algorithm specialized for generating hashes of the required length. Thus, we proposed whole new algorithm. We also wanted to forge encryption keys based on key-files and do not limit only for passwords as the source. So, this paper presents the design of the final algorithm and results from testing it. This work is also the first proposal and in the future is planned to test it more.

This paper introduces a tool suitable for rapid packet processing - DPDK and two frameworks for packet processing based on DPDK. Then we surveyed and analyzed a number of traditional load balancing algorithms. After that we expounded the different ways to classify traffic according to different rules under DPDK. With respect to RSS technology, we compared several hash algorithms used in RSS technology. Finally, we introduced a dynamic load balancing method.

In this digital world, steganography is intended to protect information from intruder, attacker and unwanted parties. Steganography is an excellent means by which security can be accomplished in transferring data over the network but it can be detected by hits comparison tools available in the market. In this paper, a new algorithm to Secure Steganographic File is proposed which is undetectable by bits comparison tool and any other method. By this algorithm, we use those bits of image RGB (Red, Green, Blue) LSB (Least significant Bit) values which are same as the value of message to be hidden. it implies that those bits of image are remembered which are same as bit of message to be encrypted. Images are send in the starting by physical means after that image number and formula (which is to be applied on that image) is transferred online in hash form. This process makes the communication hundred percent secure.

hash functions represent a fundamental building block of many network security protocols. The SHA-3 hashing algorithm is the most recently developed hash function, and the most secure. Implementation of the SHA-3 hashing algorithm in Hardware Description Language (HDL) is time demanding and tedious to debug. On the other hand, High-Level Synthesis (HLS) tools offer potential solutions to the hardware design. HLS tools provide us with advanced capabilities for design evaluation and a wide variety of optimization techniques. In this paper, the SHA-3 hashing algorithm and its implementation onto a Xilinx (R) Zynq-7000 SoPC is explored. The SHA-3 hashing algorithm is initially coded in C programming language and then implemented with Xilinx Vivado HLS. The HLS tool enabled us to quickly analyze our design to make suitable optimizations which led to increased throughput of the SHA-3 hashing algorithm, up to 2000 Mbps. After pipelining the synthesized hardware design, it was capable of hashing a block of 1088 bits in 70 clock cycles.

Rapid development of computer is followed by development of digital storage device. One common problem of digital storage device is data loss. The problem of data loss could be solved by using file carving techniques, for example. File carving techniques could be performed using carving tools, such as PhotoRec and Foremost. This research was conducted to know and to compare performance of carving process from PhotoRec and Foremost based on three parameters, which are the number of return files, file validation, and the rate of process. The research used simulation methods. The process of file validation uses hash algorithm SHA1 to make sure the similarity between original and return files. The result of this research shown with table that PhotoRec has a higher performance than Foremost. PhotoRec have return files less than Foremost, but PhotoRec has a higher percentage of valid files than Foremost. Additionally, the rate of carving file process done by PhotoRec is higher than Foremost. Finally, the research reaches the conclusion that PhotoRec is better than Foremost.

In Secure hash algorithm-3 standards, the functions are based on instance of the KECCAK algorithm. In this paper, we have implemented Secured hash algorithm (SHA3-256) for secured routing in hybrid routing technique of Mobile Ad hoc Networks (MANETs). We have used hashed Message Authentication Code (HMAC) to achieve data integrity and authentication. The hybrid routing technique which we have used was Zone Routing Protocol (ZRP), a hybrid MANET is routing protocol using Network Simulator 2 (NS2). This paper implements a HMAC-SHA3-512 algorithm in ZRP which leads to higher throughput and packet delivery fraction but at the expense of the increased end to end delay. From our performance analysis using 64-bit Intel Processor, it shows that the cost of implementing a HMAC-SHA3-512 algorithm gives 50% performance improvement over similar implementations of HAMC-SHA3-256.

At the present, paper-based libraries are a big challenge in Afghan educational organizations. This study proposes a high-tech library management system namely "e-Ketabtoon". It aims to improve the overall working of a library, digitalize and preserve Afghan valuable knowledge and cultural heritage for the next generation, and promote digital literacy among Afghan masses. The system architecture splits into two parts: server responsiveness capacity and client request capacity. We used agile development method which keeps users at the center of design process to develop valuable system. The initial lab tests indicate satisfying accuracy in term of usability.

There are some applications of military and e-commerce networks, where security of transmitted data on unfriendly environment requires more concern as compared to other design issues like power and energy consumption. Data alterations in above mentioned applications can lead to irreparable losses;so to avoid such losses, we have to maintain Data Integrity in the communication network. This paper presents a novel and reliable hash algorithm which inherits the basic architecture of SHA-1. Performance of proposed technique is compared with existing techniques through statistical test suite for random numbers. Results reveal that the suggested technique is more effective in terms of randomness than the existing algorithms. The proposed technique, thus, finds its applicability in the sensitive data environment.
