对IssuerScripts有什么要求 [英] What are the requirements for IssuerScripts

问题描述

我完全对EMV中的发卡行脚本感到困惑.我知道它们是什么，我已经读过EMV书3.我想知道是否有人对我有一个很好的总结:

I am totally stumped about Issuer Scripts in EMV. I know what they are and I have read the EMV book 3. I was wondering if anyone has a good summary that tells me:

1. 基于"86"解析脚本.
2. 然后根据某些值来执行此操作或执行该操作.

谢谢

推荐答案

EMV TAG 0x86的内容已准备就绪，可以使用智能卡的APDU命令.实际上，它可以是任何EMV或ISO 7816命令，应通过EMV终端应用程序/内核转换为智能卡，而无需进行其他修改.

Content of EMV TAG 0x86 is ready to use APDU command for the smartcard. It could be any of EMV or ISO 7816 Commands actually and should be translated to smartcard thru EMV terminal application/kernel without additional modifications.

以下是颁发者脚本的常用APDU 指令(INS):

Here are usual APDU Instructions (INS) for Issuer scripts:

- 16: EMV, Card Block
- 18: EMV, Application Unblock
- 1E: EMV, Application Block
- 24: EMV, Pin Change/Unblock
- DC: ISO 7816-4, Update Record

请记住，APDU命令中使用的消息身份验证代码(MAC)数据组件来保护(签名)命令主体.

Please keep in mind that Message Authentication Code (MAC) data component used in the APDU Command to protect(sign) the command body.

您可以在EMV手册3和ISO 7816-4中找到命令说明.

The Commands descriptions you can find in EMV Book 3 and in the ISO 7816-4.
