Abstract. In this paper, a self-adaptive encryption algorithm using by chaotic systems and Choquet fuzzy integral is presented. This algorithm has been designed considering classic of permutation-diffusion, combination of two one-dimension (1D) chaotic maps and Choquet fuzzy integral. To avoid the definite plaintext attack or chosen plaintext attack, keys which are produced for two stages (permutation and diffusion stages) are associated plain image. Thus, different keys are produced for different images. Key which is produced in permutation stage, corresponded with chaotic map and key which is made in diffusion stage based on Choquet fuzzy integral.
