【Abstract】 In this article we have studied the encryption algorithm based on DBS and its application in detail. To assure the safety of data information, we havedesign a complete set of security system using this algorithm to implement the encryption and decryption of data. And, this system is called Mobile Communication Repaying Card Encryption System. Also, we have introduced some executable improvements to DES appointed to some specific attack methods.更多还原
