| 摘 要： | 基于带记忆组合逻辑的序列发生器虽然抗传统的相关攻击,但易受线性时序电路逼近攻击.结合表更新的思想,本文给出了一类基于时变逻辑的序列发生器模型,并分析了输入输出间的相关性等密码学性质.许多密码体制都可归于此种模型,该模型对设计序列发生器有借鉴意义.

| Abstract: | The binary sequence generator with memory is vulnerable to "linear sequential circuit approximation" attack though it can resist traditional correlation attack. With the idea of table-shuffling, a kind of binary sequence generators based on time-varying binary combiner are given. Some cryptographic properties like correlation between input and output are discussed. Several known sequence generators are of this model.The model can be useful in designing sequence generators. |
