An Improved AES Algorithm Based on Chaos
Yuan Kun, Zhang Han, Zhaohui Li · 2009
It is pointed that the key space of AES encryption algorithm is limited, and there is few nonlinear factors in the whole system. In this paper, the author use two chaos systems, so the author can get two sequences. One is used as key, the other one is used to control the times of row-shift. This encryption algorithm combines the chaos theory with AES, then, a new algorithm is formed. This new method increases the key space and the nonlinear factors of AES system. In this case, the safety of encryption algorithm has been further improved.
