基于GP32的射频卡密码认证系统设计

Design of Key Authority System of Radio Frequency IC Card Based on GP32

密码认证是射频卡应用中的一项关键技术.在剖析了Mifare卡存储结构、读写控制以及加密机制的基础之上,以MC68HC908GP32为主控芯片,利用基站芯片MF RC500与天线技术的结合搭建出一个密码认证平台.软件部分重点阐述了Mifare卡与基站芯片MF RC500密码认证过程与程序实现;该系统具有作用距离远、响应速度快、使用简便、安全性高等显著特点.

Key authority is a key technology in the application of Radio Frequency. Based On analyzing the storing structure of Mifare card, controlling procedure of reading and writing and key authority system, mainly chip of MC68HC908GP32, it builds a hardware platform of key authority system associated with MF RC500 chip and antenna technology. While software focuses on the part of the Mifare cards and base stations MF RC500 chip code key authority and procedures to achieve. The system has a range far and fast response, the use of simple, safe, and other significant characteristics.
