古典密码-
本文主要讨论密码分析的方法，大体上从古典密码、对称密码、非对称密码这三种加密方法方面进行分类，并重点对穷举密码分析法、线性密码分析法、因式分解法进行探讨。
On this base , we mainly discuss the methods of cryptanalysis , then classify the methods approximately by three aspects of classical cryptogram , symmetry cryptogram and asymmetry cryptogram . In this paper , we mainly study linear cryptanalysis method , enumeration key cryptanalysis method and factorization method .
