我想将一个随机字节数组（包括例如24个元素）发送到我的JavaCard applet，然后我的applet应该使用特定方法更改该数组 . 例如，该方法使用 0x05 对每个元素进行异或，并在APDU响应中返回结果数组 .
为了实现上述目标，我到目前为止编写了以下程序：
package keyGeneratorPackage;
import javacard.framework.APDU;
import javacard.framework.ISO7816;
import javacard.framework.Applet;
import javacard.framework.ISOException;
import javacard.framework.JCSystem;
import javacard.framework.Util;
public class KeyGeneratorPackage extends Applet {
private static final byte HW_CLA = (byte) 0x80;
private static final byte HW_INS = (byte) 0x00;
public static void install(byte[] bArray, short bOffset, byte bLength) {
new keyGeneratorPackage.KeyGeneratorPackage().register(bArray, (short) (bOffset + 1),
bArray[bOffset]);
}
public void process(APDU apdu) {
if (selectingApplet()) {
return;
}
apdu.setIncomingAndReceive();
byte[] buffer = apdu.getBuffer();
byte CLA = (byte) (buffer[ISO7816.OFFSET_CLA] & 0xFF);
byte INS = (byte) (buffer[ISO7816.OFFSET_INS] & 0xFF);
short lc = (short) (buffer[ISO7816.OFFSET_LC] & (short)0x00FF);
byte[] Data = JCSystem.makeTransientByteArray(lc, JCSystem.CLEAR_ON_DESELECT);
if (CLA != HW_CLA) {
ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);
}
switch (INS) {
case HW_INS: {
// copying the apdu data into byte array Data
Util.arrayCopy(buffer, ISO7816.OFFSET_CDATA, Data, (short) 0, lc);
getKey(apdu, Data);
}
break;
default:
ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
}
}
private void getKey(APDU apdu, byte[] data) {
byte[] buffer = apdu.getBuffer();
short length = (short) data.length;
//prepareing the key array of same length of Data
byte[] key = JCSystem.makeTransientByteArray(length, JCSystem.CLEAR_ON_DESELECT);
generateKey(data, key);
Util.arrayCopyNonAtomic(key, (short) 0, buffer, (short) 0, (short) length);
apdu.setOutgoingAndSend((short) 0, length);
}
private byte[] generateKey(byte[] Data, byte[] key) {
short i;
for (i = 0; i < Data.length; i++) {
key[i] = (byte) (Data[i] ^ (byte)0x05);
}
return key;
}
}
我必须在编译并选择我的applet后发送以下APDU命令：
>>> 80 00 00 00 18 11 22 33 44 55 66 77 88 99 10 20 30 40 50 60 70 80 90 b1 b2 b3 b4 b5 b6 b7 b8
我的applet必须返回的预期数据是：
<<< 14 27 36 41 50 ... bd
我在安装此Applet时遇到问题 .
我无法将其安装到我的Java卡，而我确信我的applet和我的卡之间的Java Card版本兼容性没有问题 . 无论如何，我的程序是用Java Card Dev Kit 2.2.1编译的 .
值得注意的是，我创建了一个默认的Java Card项目，没有任何额外的代码，并且它已成功安装在我的卡上 . 它也是由JavaCard开发工具包2.2.1版编译的 .
我使用globalPlatformPro来安装我的applet，它在状态字中给了我 0x6700 错误 .
Update 1:
我用-v -d参数输入了install命令 . OutPut是：
E:\javacard\GlobalPlatformPro>gp -install E:\newPack.cap -v -d

我的小程序有问题吗？有什么问题？
1 回答
我可以通过gpj平台成功地在我的智能卡上安装我的applet . 在gpj平台上安装的输出是：
我无法通过globalPlatformPro在智能卡上安装我的applet . 我不知道原因，无论如何在这个平台上安装命令的输出是：
这是我的卡上的小程序列表，其中最后四个AID和前四个AID是我的应用程序包和通过gpj安装的应用程序小程序 .
这是我的最终applet代码：
为了将我的命令发送到卡上安装的applet，我使用的是OpenSc工具 . 输入和输出在这里：
