| 摘 要： | 讨论了一种预付ＩＣ卡芯片设计中使用的两种安全措施－传输代码验证和双向鉴别，给出了设计方法。正确的传输代码验证是ＩＣ卡个人化的前提条件，它是通过传输代码比较的结果去控制电压转换的输出实现的。双向鉴别是对ＩＣ卡和主机各自合法身分的确认，其核心是加密电路。

| Abstract: | Two security measures, transport code verification and bidirectional authentication, used for an IC card chip for prepayment are discussed in the paper. The design technique is de- scribed. Correct transport code verification is accomplished by controlling the output of the voltage conversion circuit with comparisons of transport codes. Bidirectional authentication is the verifica- tion of the legal status of IC cards and computer terminals. The core structure of the bidirectional authentication is an encrypting circuit. |
