A one-way-coupled chaotic map lattice is proposed for cryptography of self-synchronizing stream cipher. The system performs basic floating-point analytical computation on real numbers, incorporating auxiliarily with few simple algebraic operations on integer numbers. Parallel encryption (decryption) operations of multiple chaotic sites are conducted. It is observed that the system has high practical security, fast encryption (decryption) speed with software realization, and excellent reliability against strong channel noise, and its overall cryptographic properties are considerably better than both known chaotic cryptosystems and currently used conventional cryptosystems, including the advanced encryption standard.
提出了一种用于自同步流密码加密的单向耦合混沌映射格。该系统对实数进行基本的浮点分析计算，并辅助进行少量简单的整数代数运算。对多个混沌站点进行并行加密（解密）操作。结果表明，该系统具有较高的实际安全性，软件实现时加密（解密）速度快，对强信道噪声具有优异的可靠性，其整体加密特性明显优于已知的混沌密码系统和目前使用的传统密码系统，包括高级加密标准。
