c++ - 如何使用带有 ISO14443 层的 T=CL(ISO7816) 协议(protocol)发送 APDU 命令

标签 c++ javacard apdu mifare

我想通过 T=CL 协议(protocol)与 ISO14443A 层的卡连接。并且，例如，向它发送 APDU 命令 { 0xFF, 0xCA, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 } - 它必须返回卡 ID。

为此，我使用了 librfid 库和阅读器 NXP CLRC 632 设备。

我正在重写文件 rfid_reader_spidev.c 中 librfid 中的所有函数比如:

int spidev_read(unsigned char reg, unsigned char len, const unsigned char *buf);
int spidev_write(unsigned char reg, unsigned char len, const unsigned char *buf);
int spidev_reg_read(struct rfid_asic_transport_handle *rath, unsigned char reg, unsigned char *value);
int spidev_reg_write(struct rfid_asic_transport_handle *rath, unsigned char reg, unsigned char value);

在我的设备上工作。

然后我从librfid-tool.c重写了main函数:

int main(int argc, char *argv[])  
{ 

      int rc;
    unsigned char buf[0x100];
    unsigned int len;
    unsigned int protocol = RFID_PROTOCOL_TCL,
                 layer2 = RFID_LAYER2_ISO14443A;

    printf("initializing librfid\n");
    //--------------------------------
    if (reader_init() < 0){
        printf("Err reader_init\n");
        return;
    }
    if (l2_init(layer2) < 0) {
            rfid_reader_close(rh);
            printf("Err l2_init\n");
            return;
    }
    if (l3_init(protocol) < 0) {
            rfid_reader_close(rh);
            printf("Err l3_init\n");
            return;
    }
    //--------------------------------
    printf("Protocol T=CL\n");
    // we've established T=CL at this point
    printf("selecting Master File\n");
    rc = select_mf();
    if (rc < 0) {
            printf("error selecting MF\n");
            return;
    }

    printf("Send APDU command\n");
    rc = send_apdu();
    if (rc < 0) {
            printf("error sending APDU command\n");
            return;
    }

    printf("Getting random challenge, length 255\n");
    rc = iso7816_get_challenge(0xff);
    if (rc < 0) {
            printf("error getting random challenge\n");
            return;
    }
    printf("selecting Passport application\n");
    rc = iso7816_select_application();
    if (rc < 0) {
            printf("error selecting passport application\n");
            return;
    }
    printf("selecting EF 0x1e\n");
    rc = iso7816_select_ef(0x011e);
    if (rc < 0) {
            printf("error selecting EF 0x1e\n");
            return;
    }
    printf("selecting EF 0x01\n");
    rc = iso7816_select_ef(0x0101);
    if (rc < 0) {
            printf("error selecting EF 0x01\n");
            return;
    }
    while (1) {
            printf("reading EF1\n");
            len = sizeof(buf);
            printf("reading ef\n");
            rc = iso7816_read_binary(buf, &len);
            if (rc < 0) {
                    printf("error reading EF\n");
                    return;
            }
    }
}

我添加了函数 send_apdu，但我不知道它的规则:

static int send_apdu(void)
{
  unsigned char apdu[] = { 0xFF, 0xCA, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
  unsigned char msg[128];
  unsigned char ret[256];
  unsigned int rlen = sizeof(ret), msglen;
  int rv;

  msg[0] = 0x6f;//PC_to_RDR_XfrBlock;
  msg[5] = 0;    /* slot */
  msg[6] = 1;    //seqno = handle->seqno++;
  msg[7] = 4; /* bBWI */
  msg[8] = 0; /* RFU */
  msg[9] = 0; /* RFU */
  memcpy (msg+10, apdu, 8);
  set_msg_len (msg, 8);
  msglen = 10 + 8;

  rv = rfid_protocol_transceive(ph, msg, msglen/*sizeof(apdu)*/, ret, &rlen, 0, 0);
  if (rv < 0)
    return rv;

  printf("%d: [%s]\n", rlen, hexdump(ret, rlen));
  return 0;
}

如您在日志中所见，我在程序中的“选择主文件”步骤出现错误:

如果您能帮助我或指出我的错误，我将不胜感激。

最佳答案

select_mf 函数(您未提供)中似乎有错误。从日志文件中，它正在发送:

02 00 a4 00 00 02 3f

这应该是:

00 a4 00 00 02 3f 00
