摘　　要：研究了基于双混沌系统伪随机比特发生器(CCS-PRBG)生成序列的密码学性质,证明了此二进制序列是i.i.d.序列。理论分析表明,CCS-PRBG可生成具有理想保密性的二进制混沌密码序列。The cryptographic properties of digital pseudo-random bit generator based on couple chaotic systems （CCS-PRBG） was studied and the output keystream of CCS-PRBG being i. i. d. sequence was proved. Theoretical analyses show that CCS-PRBG have good cryptographic properties and can be used to generate stream ciphers with high security.
