Abstract

Advanced Encryption Standard (AES) has been widely used in wireless communications with advantage of the small amount of computation and fast speed. In order to overcome the drawback of typical expansion algorithm whose key is easily attacked by Square, an improved AES algorithm is proposed. In this algorithm, the double S-box model, the only non-linear structure, is employed to increase the diffusivity of data. Experimental results indicate that this AES algorithm can improve the security of the key in the same condition of algorithm efficiency.
