Using Linear Difference Equations to Model Nonlinear Cryptographic Sequences
摘要：
本文提出了一类新的基于元胞自动机的线性序列生成器，并对几种在对称密码学中具有实际应用的非线性密钥流生成器进行了建模。将输出序列表示为线性差分方程的解，分析了输出序列的周期、线性复杂度和不同输出序列个数等基本性质。
英文摘要：
A new class of linear sequence generators based on cellular automata is here introduced in order to model several nonlinear keystream generators with practical applications in symmetric cryptography. The output sequences are written as solutions of linear difference equations, and three basic properties (period, linear complexity and number of different output sequences) are analyzed.
