Advanced approach for encryption using advanced encryption standard with chaotic map

At present, security is significant for individuals and organizations. All information need to prevent theft, leakage, alteration. Security must be guaranteed by applying some or combining cryptography algorithms the information. Encipherment method that changes plaintext a secure form called cipherment. includes diverse types, such as symmetric asymmetric encipherment. This study proposes an improved version of advanced encryption standard (AES) algorithm optimized (OAES). The OAES utilizes sine map random number generate new key enhance complexity generated key. Thereafter, multiplication operation was performed on original text, thereby creating matrix (4×4) before five stages coding cycles. A substitution-box (S-Box) utilized instead fixed S-Box. Finally, we eXclusive OR (XOR) with digit 255, also last. research compared features AES algorithms, particularly extent complexity, size, rounds. can decryption using values, S-Box, chaotic maps, resulting in difficulty guessing text.
