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

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.
