| 摘 要： | 由混沌映射驱动得到的伪随机二进制序列应确保有足够的比特安全性。信息有规律地泄漏,会导致有可能利用有限长度的输出序列完全地破译混沌驱动序列,并恢复有限长度的初始密钥,重建全部的输出序列。

| Abstract: | Sufficient bit security is necessary for pseudorandom binary sequences drived by chaotic maps.Regular leakage of information can make the result that chaotic drived sequences can be broken using output sequences of a limited length to recover initial,secret key of a limited bits and reconstruct all output sequences. |
