Mifare身份验证 [英] Mifare authentication

问题描述

说我想通过Mifare Classic进行身份验证.

Say I want to authenticate to Mifare Classic.

我怎么知道要发送到卡的APDU的确切类型?

How do I know the exact kind of APDU to send to the card?

示例.

此代码:

bcla = 0xFF;
bins = 0x86;
bp1 =  0x0;
bp2 =  0x0; // currentBlock
len =  0x5;

sendBuffer[0] = bcla;
sendBuffer[1] = bins;
sendBuffer[2] = bp1;
sendBuffer[3] = bp2;
sendBuffer[4] = len;
sendBuffer[5] = 0x1;                // Version
sendBuffer[6] = 0x0;                // Address MSB
sendBuffer[7] = currentBlock;
if(keyradioButton->Checked==true)   // Address LSB
     sendBuffer[8] = 0x60;              // Key Type A
else if(keynumberradioButton->Checked ==true)
    sendBuffer[8] = 0x61;               // Key Type B
sendBuffer[9] = keynumber;          // Key Number

sendbufferlen = 0xA;
receivebufferlen = 255;

//Invoke the Transmit command
retval = SCardTransmit(hCard,  // A reference value returned from the SCardConnect function.
                                 &sioreq, 
                              sendBuffer,  // Send buffer
                           sendbufferlen,  // Send buffer length
                                 &rioreq, 
                           receiveBuffer,  // Receive butter
                      &receivebufferlen);  // Length of received buffer

是一个示例程序，试图对Mifare Classic进行身份验证. 我的问题基本上是，我如何知道要发送到卡的哪种APDU?例如，我怎么知道sendBuffer应该是什么?

is a sample program which tries to authenticate to Mifare Classic. My question is basically, how do I know what kind of APDU to send to the card? e.g., how do I know what should be in the sendBuffer?
