基于扰乱器对DES加密算法安全性提高的论证

Scrambler Based on the DES Encryption Algorithm to Improve the Security Argument

DES是一种应用非常广泛和成熟的数据加密算法.在深入剖析DES加密算法原理基础上,提出了一种改进的DES加密方案,该方案通过对64位密钥变换后的结果进行扰乱,使得设计后的加密体系安全性更高;同时对扰乱器的原理进行了数学验证,证明了改进方案的可靠性;而软件设计结果,进一步论证了改进方案的可行性.

DES is a widely used and mature data encryption algorithm. This paper analysis the principle of DES algorithm and its advantages and disadvantages and propose a DES improvement program, which the 64-bit key transformation by the results after the disruption, making the system more secure. Also on the design principle of Scrambler having mathematical proof, and gives the results of software design, and further proof s its feasibility.
