提出了基于耦合混沌和触发细胞自动机的图像加密算法。首先用耦合混沌系统对图像进行加密,然后用耦合二维细胞自动机再次加密,最后用混沌序列对图像进行置乱。加密过程中同时运用了分组加密和流加密方法。仿真实验结果表明,该加密算法实现简单,扩散和混淆效果比较理想,有较强的抗攻击能力,具有良好的加密效果。
提齣瞭基于耦閤混沌和觸髮細胞自動機的圖像加密算法。首先用耦閤混沌繫統對圖像進行加密,然後用耦閤二維細胞自動機再次加密,最後用混沌序列對圖像進行置亂。加密過程中同時運用瞭分組加密和流加密方法。倣真實驗結果錶明,該加密算法實現簡單,擴散和混淆效果比較理想,有較彊的抗攻擊能力,具有良好的加密效果。

This article proposes an image encryption algorithm based on coupled chaotic system and coupled trigger cellular automata . Firstly , it uses coupled chaotic systems to complete the image encryption , then uses couple cellular automata as the method of the second encryption , finally uses another chaotic system for image scrambling . Block cipher and stream cipher are both used . The simulation results show that this encryption algorithm is easy to realize , which is characterized by excellent diffusion and confusion properties , and also has stronger anti-attack capability and good effect of encryption .
