| 摘 要： | 提出一个基于耦合映射格子的混沌块密码系统，设计一种明文块加密顺序的动态更新规则，每次更新的子区域顺序以及不同子区域明密文之间的复杂反馈关联均使得明密文之间的规律更加隐蔽。采用简单一维混沌映射，仿真实验表明，与类似的混沌加密算法比较，得出的各项统计数据均显示该系统具有较高的安全性及加解密效率。

| Abstract: | This paper proposes a block chaotic cryptosystem based on Coupled Map Lattice(CML). The encryption order of the plaintext blocks is updated dynamically by certain rule. The updating order of sub-regions and the complex feedback association of different sub-regions make the law between plaintext and ciphertext more secret. All the chaotic maps used in the scheme are simple one dimensional. Both experimental results and comparisons with similar chaotic cryptosystems prove that the proposed cryptosystem has obvious advantages of security and high efficiency of encryption and decryption. |
