Implement A Novel Symmetric Block Cipher Algorithm
Ali M Alshahrani, Stuart Walker · International Journal on Cryptography and Information Security · 2014
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.
