Plaintext-related image encryption algorithm based on perceptron-like network

Abstract

A perceptron-like network based on integer domain was proposed, and then a new image cryptosystem based on the network was proposed in this paper. Different from the structure of classical image cryptosystem, the proposed image cryptosystem employed the perceptron-like network to achieve the diffusion of image information. It firstly generated the pseudo-random key streams from the secret key through chaotic system and S-box of AES. Then it obscured the sequence of plain image by XOR operation. Next, it used two perceptron-like networks to fulfill the information memory and diffusion of the image sequence. Finally, it obscured the diffused sequence using the equivalent keys to obtain the cipher image sequence. Performance analysis and comparison analysis show that the proposed image cryptosystem has the advantages of fast processing speed, strong system sensitivity and high security, and can be applied to the actual image communications.
