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。
#--- Importing required modules.
import sys

sys.path.append("D:\\PythonX\\Lib\\site-packages")

from smartcard.System import readers

exit()

#--- An struct for APDU responses consist of Data, SW1 and SW2
class stru:

self.data = list()
self.sw1 = 0
self.sw2 = 0
resp = stru()

for cmd in cmds:
#--- Following 5 line added to have a good format of command in the output.
temp = stru() ;
temp.data[:]=cmd[:]
temp.sw1=12
temp.sw2=32
modifyFormat(temp)
print "req: ", temp.data
resp.data,resp.sw1,resp.sw2 = connection.transmit(cmd)
modifyFormat(resp)
printResponse(resp)
def modifyFormat(resp):
resp.sw1=hex(resp.sw1)
resp.sw2=hex(resp.sw2)
if (len(resp.sw2)<4):
resp.sw2=resp.sw2[0:2]+'0'+resp.sw2[2]
for i in range(0,len(resp.data)):
resp.data[i]=hex(resp.data[i])
if (len(resp.data[i])<4):
resp.data[i]=resp.data[i][0:2]+'0'+resp.data[i][2]
def printResponse(resp):
print "res: ", resp.data,resp.sw1,resp.sw2
send(cmds)
connection.disconnect()输出:

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:
FF 69 44 4268 92 00 04 0068 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01或02__)XX=01好的,我写了下面的Java程序:
import java.util.List;
import java.util.Scanner;
import javax.smartcardio.Card;
import javax.smartcardio.CardChannel;
import javax.smartcardio.CardException;
import javax.smartcardio.CardTerminal;
import javax.smartcardio.CommandAPDU;
import javax.smartcardio.ResponseAPDU;
import javax.smartcardio.TerminalFactory;
import javax.xml.bind.DatatypeConverter;
public class TestPCSC {
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);
Card connection = cardTerminal.connect("DIRECT");
CardChannel cardChannel = connection.getBasicChannel();
System.out.println("Write your commands in Hex form, without '0x' or Space charaters.");
System.out.println("\n---------------------------------------------------");
System.out.println("Pseudo-APDU Mode:");
System.out.println("---------------------------------------------------");
while (true) {
System.out.println("Pseudo-APDU command: (Enter 0 to send APDU command)");
String cmd = scanner.nextLine();
if (cmd.equals("0")) {
break;
}
System.out.println("Command : " + cmd);
byte[] cmdArray = hexStringToByteArray(cmd);
byte[] resp = connection.transmitControlCommand(CONTROL_CODE(), cmdArray);
String hex = DatatypeConverter.printHexBinary(resp);
System.out.println("Response : " + hex + "\n");
}
System.out.println("\n---------------------------------------------------");
System.out.println("APDU Mode:");
System.out.println("---------------------------------------------------");
while (true) {
System.out.println("APDU command: (Enter 0 to exit)");
String cmd = scanner.nextLine();
if (cmd.equals("0")) {
break;
}
System.out.println("Command : " + cmd);
byte[] cmdArray = hexStringToByteArray(cmd);
ResponseAPDU resp = cardChannel.transmit(new CommandAPDU(cmdArray));
byte[] respB = resp.getBytes();
String hex = DatatypeConverter.printHexBinary(respB);
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.transmitControlCommand和cardChannel.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。
让我们看看非接触式阅读器的输出:

是的,有两个问题!

Java Result: 1
BUILD SUCCESSFUL (total time: 39 seconds)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.transmitControlCommand和cardChannel.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。
