对于EMV中的GETCHALLENGE请求(0084000000),我们得到VISA \ DEBIT卡的肯定响应,但对于MASTERCARD,我们得到的响应为6D00(指令代码不受支持或无效)。
以下是在万事达卡的情况下,在调用Get Challenge之前执行的命令序列。您可以看到CDOL具有ICC Dynamic number的标记,当通过执行get Challenge命令获取动态数字的调用时,我得到不支持指令代码的错误消息。

对于CDOL的ICC动态编号,在GPO之后,需要向卡发出内部认证。这将为您提供签名动态应用程序数据(这是在ICC私钥下签名的证书)。
以下是您使用ICC公钥打开的证书内容。您可以看到ICC动态数据,其中08是长度, C7C298C8C60E2984 是您的动态数字。干杯,享受!!
至于如何完成,您需要阅读EMV 4.3 Book 2 安全和密钥管理第6节,离线动态数据认证。快乐学习。 一旦完成,请告诉我,并接受此答案
