Abstract: This paper introduces a self-adaptive gray image encryption algorithm to encrypt color images. In terms of two flaws including dissatisfied security and low efficiency, Coupled Map Lattice(CML) and AMS transformation are adopted to make up the deficiencies. Theoretical analysis and simulation experiment demonstrate the simplicity and high speed of the algorithm. It can be used in the actual parallel computing platform with high security.

Key words: self-adaptive encryption, AMS transformation, Coupled Map Lattice(CML), color image encryption
