Colour image encryption based on advanced encryption standard algorithm with two-dimensional chaotic map
In this study, a novel scheme of advanced encryption standard (AES) is proposed. Its independent round key is generated by the two-dimensional (2D) Henon map and the 2D Chebyshev map. The goal is to improve the low security and conquer the defect of the traditional AES algorithm. Then, the improved algorithm is used to encrypt colour image, and the result shows that the encryption algorithm has better security by cryptanalysis.
