摘要
针对混沌理论在密码学应用中的安全问题,基于离散耦合映像格子和渐进确定性随机理论,设计了一种混沌块加密算法.该算法使用渐进确定性随机产生的密钥对明文进行扩散,并通过对离散耦合映像格子的迭代而进行加密.对其进行有效性测试及敏感度分析和抵抗统计分析,结果表明,该混沌加密算法具有较高的安全性.
Aiming at the security problem of chaos theory in cryptography application,a chaotic block encryption algorithm was designed based on the theory of discrete coupled map lattice and asymptotic deter-ministic randomness.The algorithm used aymptotic deterministic randomness key to diffuse the plaintext, and through the iteration of the discrete coupled map lattice the plaintext was encrypted.Then the validity, sensitivity and resistance of algorithm were tested and analyzed.The results showed that the security of cha-otic encryption algorithm was higher.
