实现逻辑加密型IC卡一卡一码的一种有效算法

An Effective Algorithm for Logical Security IC Card's One Card One Code

为不同的逻辑加密型ＩＣ卡设置不同的密码（即一卡一码），可以使应用系统的安全性大大提高。本文利用ＤＥＳ算法中的Ｓ变换，设计出一种实现该类型ＩＣ卡一卡一码的有效算法。

:Setting distinct secret code for different logical Security IC Card(namely one card one code), the security of the applied system is greatly improved. In this paper, making use of the S B0X of the DES Algorithm, an effective algorithm for this kind of IC card's one card one code is designed and its security is simply analysed.
