Comparative Analysis of Block Cipher-Based Encryption Algorithms: A Survey

Nowadays, network security is increasing rapidly and becoming an important and challenging issue. Information and internet security threats and attacks are becoming difficult to be detected. Therefore, encryption has come up as a solution, and plays an important role in information security system. Many techniques are needed to protect the shared data. In this paper we implemented four encrypt techniques AES, DES, 3DES and E-DES algorithms and compared their performance. A comparative analysis on the above symmetric encryption algorithms has been made. These algorithms consume a significant amount of computing resources such as CPU time, memory and battery power. Experiments results are given to analyses the effectiveness of each algorithm. The comparison is made on the basis of these parameters: speed, block size, and key size etc. Educational-DES has better performance than other DES, 3DES, and AES algorithms.

Implement A Novel Symmetric Block Cipher Algorithm

Cryptography technology is a security technique used to change plain text to another shape of data or to symbols, which is known as the cipher text. Cryptography aims to keep the data secure during its journey through public networks. Currently, there are many proposed algorithms that provide this service especially for sensitive data or very important conversations either through mobile or video conferences. In this paper, an inventive security symmetric algorithm is implemented and evaluated, and its performance is compared to the AES. The algorithm has four different rounds for each quarter of the key container table, and each of them serves to shift the table. The algorithm uses the XOR operation, which, being lightweight and cheap, is very appropriate for use with Real Time Applications. The result shows that the suggested algorithm spends less time than AES although it has 16 rounds and the numbers used to mix up the table are big.

Modified Advanced Encryption Standard Algorithm for Information Security

Symmetry

The wide acceptability of Advanced Encryption Standard (AES) as the most efficient of all of the symmetric cryptographic techniques has further opened it up to more attacks. Efforts that were aimed at securing information while using AES is still being undermined by the activities of attackers This has further necessitated the need for researchers to come up with ways of enhancing the strength of AES. This article presents an enhanced AES algorithm that was achieved by modifying its SubBytes and ShiftRows transformations. The SubBytes transformation is modified to be round key dependent, while the ShiftRows transformation is randomized. The rationale behind the modification is to make the two transformations round key dependent, so that a single bit change in the key will produce a significant change in the cipher text. The conventional and modified AES algorithms are both implemented and evaluated in terms avalanche effect and execution time. The modified AES algorithm achieved an ...

Analysis of Most Common Encryption Algorithms

Empirical Research Press Ltd. United Kingdom, 2022

As the things are settled down after the emergence of technology, and this is the decade of professionalism as far as technology is concerned, security of data is the major hurdle in this race. This is the era in which data is one click away from the users, so data needs to be more secured so that it can be avoided unauthorized access. For this purpose, different data security fields have also emerged to ensure data security and confidentiality. In this survey paper we will look up all the techniques used for data encryption and after that, we compare those techniques to provide the best algorithm to ensure that data is secured. We go categorically, as in most of the cases, symmetric encryption technique is applicable and, in a few cases, asymmetric is recommended. Firstly, in our study, we compare both the techniques with each other and then compare all the algorithms working under the above-mentioned categories concerning their time, efficiency, memory usage, latency, key size, and several rounds which will result in showing the best algorithm according to input data.
