| Abstract: | 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 h... |
