前言:

我有一个双界面智能卡读卡器,它具有一些扩展功能(除了向卡发送APDU命令和接收APDU响应之外)。

例如,在其文档中提到,您可以使用以下命令获取读卡器的固件版本:

GET_FIRMWARE_VERSION:FF 69 44 42 05 68 92 00 05 00

在它的工具中,有一个用于该功能的按钮,它工作得很好:

我甚至闻了闻USB端口,看看我的PC和我的阅读器之间的连接到底交换了什么来实现这个功能:

命令:

响应:

问题:

我想使用其他工具或通过代码获得我的读卡器版本(也可能发送其他扩展命令),但我必须在读卡器中插入一张卡才能发送命令,否则我会收到No Card Present异常,而我不想向卡发送命令!(读卡器工具成功响应GET_FIRMWARE_VERSION,读卡器插槽中没有任何卡可用)

我到目前为止所做的:

1.我尝试了一些工具,包括OpenSCTool、PyAPDUTool和另一个读者的工具。2.我写了下面的python脚本来发送扩展命令。

但是两者都有提到的问题!

问题:

1-没有可用的卡时如何向读卡器发送扩展命令?

2-为什么在嗅探到的数据中看不到命令头?(请注意,由于标头是所有扩展命令的预先指定的固定值,我认为阅读器工具不会使用GET_FIRMWARE_VERSION命令发送标头,它只发送数据!但是它是如何工作的呢?)

更新:

通过反复试验,我发现了一些有用的东西。

假设:

  • Pseudo-APDUs固定报头= FF 69 44 42
  • Pseudo-APDU数据字段= 68 92 00 04 00
  • Pseudo-APDU数据字段GET_READER_FIRMWARE_VERSION = CHANGE_SAM_SLOT = 68 92 01 00 03 XX 00 00 (我的阅读器有两个XX插槽,因此命令可以是0102__)
  • SELECT APDU XX=01

好的,我写了下面的Java程序:

    public static void main(String[] args) throws CardException {

        TerminalFactory tf = TerminalFactory.getDefault();
        List< CardTerminal> terminals = tf.terminals().list();
        System.out.println("Available Readers:");
        System.out.println(terminals + "\n");

        Scanner scanner = new Scanner(System.in);
        System.out.print("Which reader do you want to send your commands to? (0 or 1 or ...): ");
        String input = scanner.nextLine();
        int readerNum = Integer.parseInt(input);
        CardTerminal cardTerminal = (CardTerminal) terminals.get(readerNum);

            if (cmd.equals("0")) {
                break;
            }
            System.out.println("Command  : " + cmd);

            if (cmd.equals("0")) {
                break;
            }

            byte[] cmdArray = hexStringToByteArray(cmd);

            System.out.println("Response : " + hex + "\n");
        }

        connection.disconnect(true);

    }

    public static int CONTROL_CODE() {
        String osName = System.getProperty("os.name").toLowerCase();
        if (osName.indexOf("windows") > -1) {
            /* Value used by both MS' CCID driver and SpringCard's CCID driver */
            return (0x31 << 16 | 3500 << 2);
        } else {
            /* Value used by PCSC-Lite */
            return 0x42000000 + 1;
        }

    }

    public static byte[] hexStringToByteArray(String s) {
        int len = s.length();
        byte[] data = new byte[len / 2];
        for (int i = 0; i < len; i += 2) {
            data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                    + Character.digit(s.charAt(i + 1), 16));
        }
        return data;
    }

}

在上面的程序中,我可以使用connection.transmitControlCommandcardChannel.transmit()方法向我的读者发送命令。重点是,所有使用第一种方法发送到阅读器的命令都被假定为伪APDU命令,我不应该对它们使用Psedo-APDU标头!并且所有使用第二种方法发送到阅读器的命令都被假定为常规的APDU命令,因此如果我需要通过第二种方法发送伪APDU命令,则必须向其添加伪APDU报头。

是的,有两个问题!

1-上面的程序只在第一次运行时工作正常。我的意思是,如果我停止运行并重新运行它,第二个方法会抛出一个异常:

正如你在上面看到的,我不能再使用第二种方法了,我需要关闭阅读器的电源,然后重新打开它,让它再次正常工作。

2- contact界面(我指的是SAM阅读器)总是抛出前一个异常!我的意思是第二种方法根本不起作用(既不是第一次,也不是第二次和第三次...)

请注意,我尝试了不同的阅读器,似乎这并不局限于这个阅读器。一些ACS读者在重新运行时也会遇到类似或完全相同的问题

有谁知道吗?

作为一个次要问题,Python有没有像Java一样发送伪APDU的相同方法?

最后,从读者的角度来看,connection.transmitControlCommandcardChannel.transmit()方法有什么不同?

当您停止“智能卡”服务时,该工具是否仍返回固件版本?如果是,则该工具可能使用原始IOCTL命令(DeviceIoControl来与驱动程序通信。

还可以看看this question。作者说,您必须将SCARD_PROTOCOL_UNDEFINED设置为协议参数:

SCardConnect(hSC,
             readerState.szReader,
             SCARD_SHARE_DIRECT,
             SCARD_PROTOCOL_UNDEFINED,
             &hCH,
             &dwAP
            );

我刚试过,至少在Windows10上可以用。无需插入卡即可进行通信。不过,我没有测试其他Windows版本。
