New Hybrid AES Static S-Box Algorithm Using Chaotic Maps

摘要

Methods of security need to be improved to face new techniques of data-stealing. The substitution table is the essence of the block ciphers encryption A good designing of S-Box increases the encryption algorithm security. This paper proposes two algorithms to generate modified S-Boxes; the S-Box depend on key and plaintext using the RC4 algorithm. And the S-Box depend on key and plaintext using RC4 chaotic algorithm This paper aims to expound the qualification of the proposed S-Boxes compared to the existing AES and Dynamic S-Boxes.
