摘要
根据密钥类型不同将现代密码技术分为2类:—类是对称加密(秘密钥匙加密)系统;另一类是公开密钥加密(非对称加密)系统。着重讨论DES的加密算法,详细论述了DES的算法流程,并探讨了DES算法的缺陷和漏洞。
Moderm encryption algorithm has two types as the different of key:one is the symmetrical encryption system;the other is the public key encryption system.This article mainly discusses the DES encryption algorithm, detailed states the thought of it,and attempts to discover the defect and loophole of it.
