| 摘 要： | 介绍了一种把Logistic映射产生的同步时空混沌用于信息保密传输的方案,用Matlab对整个过程进行数值实验,实现了对一张图片进行加密及解密的全过程,通过加入线性放大及同余操作降低了加密后图像与原始图像的自、互相关性,证明了该系统的可靠性,为在真实的系统中实现整个过程打下了理论基础.

| Abstract: | A model produced by Logistic synchronization of spatiotemporal chaos for confidentiality of information transmission mode in Matlab is described image encryption and decryption were achieved linear amplification and linear congruence operations were added to lower self-correlation and cross-correlation between encrypted and origin images. The system reliability was verified, this will lay the theoretical foundation to realize the entire process in real system. |
