چکیده انگلیسی
This paper proposes a new chaotic symmetric cryptographic system. At first, we use the proposed method, Game of Life permutation which is the initial pattern generated by logistic map, to confuse the plain image. Secondly, we use piecewise linear chaotic map (PWLCM) to diffuse the image, which we just process the higher half pixel to improve the speed. It will not affect the encryption results at the same time, which is because the higher 4 bits (8th, 7th, 6th and 5th) carry almost all information of the image. Experiment results and security analysis not only show that the scheme can achieve good encryption result, but also that the key space is large enough to resist against common attack.
