摘要：This paper suggests a new Advance Encryption Standard (AES) [3][9] encryption technique. New algorithm uses a 200 bit size[2] block encryption scheme and a key dependent substitution box which varies according to the 200 bit key provided by the user. Algorithm uses 200 bit key in the form of a 5*5 matrix[2] instead of using general AES 128 bit, 192 bit and 256 bit size encryption technique[3][8]. The new suggested varying substitution box [6] provides a better and secure way to the encryption of data. Substitution box is being varied using s - box rotation based on the key used for encryption. .
