Enhanced Security of Advanced Encryption Standard (ES-AES) Algorithm

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