我想發送一個包含例如24個元素的隨機字節數組到我的JavaCard小程序，然後我的小程序應該使用特定方法更改該數組。例如，該方法XOR每個元素都帶有0x05，並在APDU響應中返回結果數組。在Java Card小程序安裝過程中接收6700狀態字錯誤
要瞄準上述目標，我寫了下面的程序至今：
>>> 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
和預期：
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;
}
}
我必須編制並選擇我的小程序後發送以下APDU命令我的小程序必須返回的數據是：
<<< 14 27 36 41 50 ... bd
我在安裝此Applet時遇到問題。
我無法將它安裝到我的Java卡上，但我確信我的小應用程序和我的卡之間的Java Card版本兼容性沒有問題。無論如何，我的程序是用Java Card Dev Kit 2.2.1編譯的。
值得注意的是，我創建了一個沒有任何附加代碼的默認Java Card項目，並且它已成功安裝在我的卡上。它也是由JavaCard開發工具包版本2.2.1編譯的。
我用globalPlatformPro安裝我的小程序，它給我0x6700錯誤的狀態字。
更新1：
我進入安裝帶有-v參數-d命令。 OutPut是：
E:\javacard\GlobalPlatformPro>gp -install E:\newPack.cap -v -d

我的小程序有什麼問題嗎？什麼是問題？
請在安裝命令中使用'-d -v'參數時添加安裝過程的輸出。 I.e輸出'gp.exe -install E：\ keyGeneratorPackage.cap -v -d' – Abraham
您是否嘗試過使用相同的工具，讀取器和卡加載另一個.cap文件？有些閱讀器和卡片不喜歡數據部分長度爲255的APDU。如果可能的話，您可以爲小應用程序安裝設置較低的塊大小。 – vojta
我通過gpj成功安裝了我的小程序。但是當我發送命令發送數據並通過Opensc工具接收到更改的數據時，它會返回無效的數據，這意味着命令不正確。什麼是問題？我會用我在gpj平臺上收到的輸出更新我的問題。 –
