Abstract

Encryption is a method of coding information or any other form of confidential, private and sensitive information or data to prevent from unauthorized access, use, misuse, disclosure, destruction, modification, or disruption. Now a day, it is essential to secure data that is at rest in our computer or is transmitted via web against attacks. Several of cryptographic techniques are being used to preserve security and could be classified as: symmetric and asymmetric. A symmetric algorithm named as (AES) is selected for enhancement due to its applicability and widely used algorithm. In AES, among the four stages that are used for encryption and decryption Sub Bytes and Mix Column produce more delay. On the other side, Shift Rows stage contribute to less security level of AES because it uses easy operation that is linear in nature. To overcome these challenges, in the designed symmetrical cryptography algorithm shift row stage of AES is replaced by symmetrical transposition technique to advance security. The simulation result of our Symmetrical Transposition technique has shown better security achievement, with greater than 50% avalanche effect, which means the proposed algorithm makes better confusion and diffusion. Hence, our proposed Enhanced Security of Advanced Encryption Standard (ES-AES) algorithm has better security when compared to original Advance Encryption Standard (AES) algorithm.
