全部！

我正在尝试从 mifare 卡 1k 读取数据。
获取
我发送的 ID：0xFF 0xCA 0x00 0x00 0x00
接收：0x00 0x00 0x00 0x00 0x00 0x00 - ??? 这是正常的？

将身份验证密钥加载到阅读器
我发送：0xFF 0x82 0x00 0x00 0x06 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF
接收：90 00 - 没关系

在块 01 中进行身份验证
我发送：0xFF 0x86 0x00 0x00 0x05 0x01 0x00 0x01 0x60 0x00
接收：90 00 - 没关系

从块 01 读取数据
我发送：0xFF 0xB0 0x00 0x01 0x0F
接收：63 00 - 如何理解它的身份验证错误

我不明白——为什么？

}

谁能解释我为什么得到 63 00？谢谢。

公平地说，您的read命令必须是：“ 0xFF, 0xB0, 0x00, BLOCK, 0x10”。您发送缓冲区长度0F- 十进制 15 - 但您必须读取 16 字节，即0x10. 希望这可以帮助

在 Mifare Classic 1K 标签中有 16 个扇区，每个扇区包含 4 个块，每个块包含 16 个字节。

  1. 扇区 0 包含块 (0,1,2,3)
  2. 扇区 1 包含块 (4,5,6,7)
  3. 扇区 2 包含块 (8,9,10,11)
  4. 扇区 3 包含块 (12,13,14,15)....

从块读取或写入之前您必须使用该扇区的密钥 A 或密钥 B 验证其相应的扇区。身份验证完成后，您可以读取或写入。使用此命令，您可以使用 KEY A(60) 验证扇区 0

byte[] authenticationByte = new byte[10];  

authenticationByte = new byte[] { (byte) 0xFF, (byte) 0x86, (byte) 0x00,
 (byte) 0x00, (byte) 0x05, (byte) 0x00,(byte) 0x00, (byte) 0x04, 
                                    (byte) 0x60,(byte) 0x00 };

当身份验证成功时，您将获得 90 00。那是成功消息。否则响应为 63 00 ，表示身份验证失败。身份验证完成后，您可以读取块 (0,1,2,3)，因为扇区 0 包含 4 个块，它们是块 (0,1,2,3)。在这里，您的问题是您正在验证扇区 1，但尝试从扇区 0 的块中读取数据。有关更多详细信息，您可以阅读此答案。对不起英语不好
