Summary:In order to improve the data coding rate and transmission security, according to the inverse function of iteration skew tent map, which could be used as arithmetic coding, this paper proposed a compression and encryption scheme based on the piecewise linear chaotic map. It solved the separate problems of encoding and encryption in the existing program. The simulation results indicate that the algorithm improves the coding efficiency and unpredictability of ciphertext. At the same time, it can effectively resist the attack of selective plaintext, short plaintext attack and brute force search attack.
