Design of AES algorithm Based on Two Dimensional Logistic and Chebyshev Chaotic Mapping

In order to increasing the security of AES (Advanced Encryption Standard), one kind of AES algorithm based on the two dimensional Logistic and Chebyshev chaotic mapping is put forward. Because of the traditional AES algorithm has defect of only one key, so it is low security. Now this paper’s AES algorithm can conquers the defect. The result shows that the encryption algorithm has better security than the traditional AES.
