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.

基于类感知器网络的明文相关图像加密算法

提出了一种基于整数域的类似感知器的网络,然后提出了一种新的基于网络的图像密码系统。与经典图像密码系统的结构不同,所提出的图像密码系统采用类似感知器的网络来实现图像信息的扩散。它首先通过混沌系统和AES的S-box从秘密密钥生成伪随机密钥流。然后通过XOR操作掩盖了普通图像的序列。接下来,它使用两个类似感知器的网络来完成信息存储和图像序列的扩散。最终,它使用等效密钥遮盖了扩散序列,从而获得了密码图像序列。性能分析和比较分析表明,所提出的图像密码系统具有处理速度快的优点,
