摘要
CPU卡可以有效地杜绝IC卡被克隆,防止机密信息被修改,得到广泛使用,每个CPU卡具有相应的SAM(SafeAuthenticationModule),不同的CPU卡需要的密钥不同,所以有不同的SAM模块。为了使读卡器能够识别多种CPU卡,提出了通过使用多SAM卡模块的循坏扫描对多种SAM卡进行认证管理,实现读卡器对不同型号IC卡的支持,使用MSP430F149和多个SAM模块,设计实现了一种新型IC卡读卡器。详细介绍了IC卡和读卡器的工作原理、功能、硬软件设计。经过测试证明,读卡器具有功耗低、体积小、性能稳定等特点。
CPU card can avoid being cloned effectively, and prevent its secret messages being modified, so that it is applied widely. A CPU card has one Safe Authentication Module. In different CPU card, there is different SAM. A new method by scanning different SAM to identify many different cards is put forward in this paper. A new lower working power IC card reader is designed and implemented by using MSP430F149 MCU and many different SAM . The principle of IC card and the reader’s work principle,function,hardware and software design are introduced in details. By testing, it is proved that the reader is lower working power , small, and has high stability.
