摘要
在介绍了IC卡的逻辑结构、TimeCOS系统基础上,分析IC卡接口特点后,结合预付费电表,重点阐述单片机对IC卡进行读写电路的设计,并详细给出SAM与IC卡相互安全认证过程。该设计模型具有模块化、可靠性高等特点,具有一定可移植性。
Based on the introduction of the logic structure of the IC card and basic system of Time COS, having made the analysis of the characters of IC card interface, combined with the advance payment electric meter, this paper mainly clari-fies the design how single chip helps IC card read and write, and makes the process clear how SAM and IC card make mutual attestation. This designing model is of modularization credibility and certain transplantable function.
