Abstract In order to improve the safety performance of the image encryption algorithm, an advanced encryption standard encryption algorithm is proposed based on hybrid chaotic system. Logistic combined with Chebyshev chaotic sequence to produce two kinds of new chaotic sequences, the first hybrid chaotic matrix was used as the advanced encryption standard round keys for pixel scrambling and the another hybrid chaotic matrix is used as S-box for position scrambling. In addition, do shift row and mixcolumn operation will be shifted to change the pixel position and realize the dynamic transform key of advanced encryption standard image encryption. Experiment shows that the algorithm possesses the features of sensitive key dependence, good scrambling effect and efficiency.
