A Survey on the Cryptographic Encryption Algorithms

Abstract

Abstract-Security is the major concern when the sensitive information is stored and transferred across the internet where the information is no longer protected by physical boundaries. Cryptography is an essential, effective and efficient component to ensure the secure communication between the different entities by transferring unintelligible information and only the authorized recipient can be able to access the information. The right selection of cryptographic algorithm is important for secure communication that provides more security, accuracy and efficiency. In this paper, we examine the security aspects and processes involved in the design and implementation of most widely used symmetric encryption algorithms such as Data Encryption Standard (DES), Triple Data Encryption Standard (3DES), Blowfish, Advanced Encryption Standard (AES) and Hybrid Cubes Encryption Algorithm (HiSea). Furthermore, this paper evaluated and compared the performance of these encryption algorithms based on encryption and decryption time, throughput, key size, avalanche effect, memory, correlation assessment and entropy. Thus, amongst the existing cryptographic algorithm, we choose a suitable encryption algorithm based on different parameters that are best fit to the user requirements.

Research on Various Cryptography Techniques

“…4) Throughput: Is computed through way of dividing the whole encoded block size on the entire encode time. The power consumption of the algorithm will decrease, if the throughput cost increases [2].…”

“…4 and 5 illustrate the S-DES. [2]. It comprises the same steps as S-DES and processes a 64-bit input with a preliminary permutation.…”

“…A substitute for DES, 3DES shows improved key size and applies the DES algorithm 3 rounds in each data block. The key length for the 3DES is 112 and 168 bits, the number of rounds is 48 and the block length is 64 bits [2]. This algorithm aims to increase protection and security through its longer key size relative to DES.…”

“…Blowfish ordinarily makes use of 4 S-boxes rather than of one S-box. It requires additional processing time because it relies on key length, however it provides strong safety [2].…”

“…The steps for every round include of 4 layers, particularly, replacement byte, shift rows, blend column and add round key as appear in Fig. 7 [2].…”
