According to the scheme of image encryption based on matrix transformation, we proposed a new color image encryption algorithm, which exert a perturbation on the chaotic system. Then we make statistical analysis, key space and key sensitivity analysis, sequence random analysis on the proposed algorithm. The results show that the distribution of pixel-values of the encrypted image has a random-like behavior. And the key space of the algorithm is large enough to resist strong attack, so we can say this scheme is of high security.
