摘　　要：对于流密码体制中使用的伪随机序列,我们要求它既要有尽可能大的线性复杂度,又要能抗相关攻击。本文讨论了一种新的具有以上特性的钟控伪随机序列,对这种序列的线性复杂度和统计特性进行了研究,并对其不安全的一类给出了一种有效的破译算法。For cryptologic applications, it is of course highly disirable that the linear complexities of pseudorandom sequences be as large as possible, and the sequences resist the correlation attack. This paper deals with a new kind of model of clock controlled sequences which has the above properties. The linear complexity of the sequences is obtained, and the statistical piop erties of the sequences are discussed. A powerful algorithm for attacking the clock controlled sequence is obtained.
