摘要
对基于DES标准的加密算法的应用进行了研究;利用该算法,在移动通信充值卡加密系统中实现了对数据的加密的解密处理,满足了用户及系统对数据安全可靠性的要求,针对某些特殊的攻击方法,介绍了一些对DES加密算法的可行的改进。
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.
