SELECT APDU 不能正常工作

Question

我创建了一个包（AID=0102030405），里面有两个小程序。

这是第一个小程序 (AID=01020304050202020202) 的程序，它将 bArray 的内容存储到静态文件中，returns 它在处理方法中：

package processMethodArguments;

import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISOException;
import javacard.framework.Util;

public class ArgumentReturner extends Applet {
//this is my static field that I want store bArray (the install method argument) in it.
    public static byte[] theArray={(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff,(byte)0xff};
    public static short arrayLength=(short)0xFF;

    private ArgumentReturner() {
    }

    public static void install(byte bArray[], short bOffset, byte bLength)
            throws ISOException {

        new ArgumentReturner().register();

        //Storing bArray in theArray.
        ArgumentReturner.arrayLength=(short)bArray.length;
        Util.arrayCopyNonAtomic(bArray, (short)0,ArgumentReturner.theArray , (short) 0, ArgumentReturner.arrayLength);    


    }

    public void process(APDU apdu) throws ISOException {
        //returning theArray (=bArray) in response of any command.
        byte[] buffer=apdu.getBuffer();
        Util.arrayCopyNonAtomic(ArgumentReturner.theArray, (short)0,buffer , (short) 0, ArgumentReturner.arrayLength); 
        apdu.setOutgoingAndSend((short)0, (short)255);
    }

}

这是第二个小程序 (AID=010203040502) 什么都不做的程序：

package processMethodArguments;

import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISOException;

public class SecondApplet extends Applet {

    private SecondApplet() {
    }

    public static void install(byte bArray[], short bOffset, byte bLength)
            throws ISOException {
        new SecondApplet().register();
    }

    public void process(APDU arg0) throws ISOException {
        // Nothing to do. So in reception of any command, it must return only 0x9000

    }

}

我成功转换并在我的卡上安装了这个包：

GP: gp -install D:\bArrayAccessibility\processMethodArguments.cap

GP: gp -list

现在，问题是：当我 select 第一个小程序或第二个小程序时，都 returns APDU 缓冲区 (=theArray) :

问：为什么会这样？

为什么两个命令都选择第一个小程序？

Answer 1

AID 是分级的。 Java Card 运行时简单地选择第一个匹配给定字节的，即使 AID 包含更多字节。如果您再次发射 SELECT，它可能 select 第二个。

要解决此问题，请提供即使对于最短 AID 中的字节也是不同的 Applet AID。
