MIFARE Classic标准钥匙 [英] MIFARE Classic standard keys

问题描述

我有两个NFC标签，它们的扇区具有不同的键:

I have two NFC tags with different keys for their sectors:

• 标签1:该标签包含NDEF消息.

• Tag 1: This tag contains an NDEF message.

• 扇区0 =键A的 A0:A1:A2:A3:A4:A5
• 扇区1到15 =键A的 D3:F7:D3:F7:D3:F7

标签2:此标签上没有NDEF数据

Tag 2: No NDEF data on this tag

• 所有扇区=键A和B的 FF:FF:FF:FF:FF:FF

是否有符合NDEF/non-NDEF的MIFARE Classic标签的标准密钥?

Are there standard keys for MIFARE Classic tags according NDEF/non-NDEF?

推荐答案

正确.

应用笔记 将MIFARE Classic转换为NFC类型MIFARE Classic标签 定义如何使用MIFARE Classic标签存储NDEF数据.本应用笔记定义了所有包含NDEF数据的扇区都必须使用键A读取，该键的值为 D3 F7 D3 F7 D3 F7 .因此，所有数据扇区(扇区> = 1)都可以使用键A = D3 F7 D3 F7 D3 F7 来固定.

The application note MIFARE Classic as NFC Type MIFARE Classic Tag defines how a MIFARE Classic tag can be used to store NDEF data. This application note defines that all sectors containing NDEF data must be readable with a key A with the value D3 F7 D3 F7 D3 F7. Consequently, all data sectors (sector >= 1) are reable with key A = D3 F7 D3 F7 D3 F7.

此外，标签必须包含一个MIFARE应用程序目录，在该目录中，数据扇区被标记为包含NDEF应用程序.应用笔记 MIFARE应用目录(MAD)定义了MAD的结构，并且还要求MAD扇区可通过键A读取，该键的值为 A0 A1 A2 A3 A4 A5 .因此，MAD扇区(扇区0)可以通过键A = A0 A1 A2 A3 A4 A5 来启用.

Moreover, the tag must contain a MIFARE application directory where the data sectors are marked as containing the NDEF application. The application note MIFARE Application Directory (MAD) defines the structure of the MAD and it also requires that the MAD sector(s) are readable with a key A with the value A0 A1 A2 A3 A4 A5. Consequently, the MAD sector (sector 0) is reable with key A = A0 A1 A2 A3 A4 A5.

最后，MIFARE Classic标签的默认传输配置(即当它们从工厂发货时)是所有扇区均可读写的，可以使用键A = FF FF FF FF FF FF .

Finally, the default transport configuration for MIFARE Classic tags (i.e. when they ship from factory) is all sectors readble and writable with key A = FF FF FF FF FF FF.
