a novel image encryption scheme based on evensymmetric chaotic maps and skew tent chaotic map was proposed. In the permutation process, a P-box produced by sorting an even-symmetric chaotic sequence is applied to shuffle the position of all image pixels. In the diffusion process, both even-symmetric chaotic maps and skew tent map are used to generate the key stream. Then the pixels in the permutedimage determine which of two even-symmetric chaotic maps to iterate for next byte in the keystream

Results are encouraging and suggest that the scheme is reliable to be adopted for the secure image communication application.
