摘　　要：提出了由单向二维耦合的映象格点组成新的时空混沌自同步流密码系统,它能够产生并输出N2个平行混沌流密码.研究表明,该系统具有高安全性、快加密(解密)速度和强抗信道噪声能力,它的密码性质优于所有已知的混沌密码系统.A two-dimensional one-way coupled map lattice is proposed for cryptography of self- synchronizing stream cipher, which N^2 space units produce chaotic stream outputs in parallel. It is observed that the system has high practical security, fast encryption （decryption） speed and excellent reliability against strong channel noise, and its overall cryptographic properties are considerably better than known chaotic cryptosystems.

关 键 词：自同步流密码 时空混沌 自我检测 自我纠错
