摘要
研究并设计了一种可联机使用也可单独使用的高安全性无线IC卡读写模块,它以AT89C51单片机为微控制器,以MF RC500芯片为IC卡读写器,构建出了一个使用简单、可联机操作也可单机使用的IC卡读写系统,并对系统中基于MF RC500芯片构成的读写模块,以及微控制器与读写芯片的通讯方式作了详细介绍。本系统的最大特点在于其高安全性的数据加密算法。
A high security access control system based on IC card technology is designed and realized in this paper. The AT89C51 microcomputer used as micro-controUer and the MF RCS00 r/w chip constitute the system which can operate on-line or not. The reading and writing module based on MF RCS00 chip and the communication between the module and the micro-controUer are described in detail. The most major characteristic of this system is its data encryption algorithm of high security.
