java - 在 J3A081 上安装小程序(Java 卡)

我刚刚创建了一个非常简单的小程序。它是 Java 卡技术中的“hello world”。我在下面粘贴了一段代码。

public class helloworld extends Applet {
    private byte[] echoBytes;
    private static final short LENGTH_ECHO_BYTES = 256;
    /**
     * Installs this applet.
     * 
     * @param bArray
     *            the array containing installation parameters
     * @param bOffset
     *            the starting offset in bArray
     * @param bLength
     *            the length in bytes of the parameter data in bArray
     */
    public static void install(byte[] bArray, short bOffset, byte bLength) {
        new helloworld();
    }

    /**
     * Only this class's install method should create the applet object.
     */
    protected helloworld() {
        echoBytes = new byte[LENGTH_ECHO_BYTES];
        register();
    }

    /**
     * Processes an incoming APDU.
     * 
     * @see APDU
     * @param apdu
     *            the incoming APDU
     */
    @Override
    public void process(APDU apdu) {
        //Insert your code here
        //
        byte buffer[] = apdu.getBuffer();
        if ((buffer[ISO7816.OFFSET_CLA] ==  0) && (buffer[ISO7816.OFFSET_INS] == (byte) (0xA4))){
            return;
        }
        short bytesRead = apdu.setIncomingAndReceive();
        short echoOffset = (short) 0;

        Util.arrayCopyNonAtomic(buffer, ISO7816.OFFSET_CDATA, echoBytes, echoOffset, bytesRead);
        echoOffset += bytesRead;

        apdu.setOutgoing();
        apdu.setOutgoingLength((short)(echoOffset + 5));

        //echo header
        apdu.sendBytes((short) 0, (short) 5);
        //echo data
        apdu.sendBytesLong(echoBytes, (short) 0, echoOffset);
    }
}

之后，我决定使用 Global Platform 将其安装到真实卡 (J3A081) 上，但失败了。首先，我用命令检查卡上是否已经安装了任何小程序:

java -jar gp.jar -l

响应是:

AID: A000000003000000 (|........|)
     ISD OP_READY: Security Domain, Card lock, Card terminate, Default selected, CVM (PIN) management

当我决定使用 *.cap 文件安装小程序时，我得到了:

java -jar gp.jar -install krystian.cap

你能告诉我我做错了什么吗？这张卡是全新的，以前从未使用过。我正在使用 NXP 的 ACR122U NFC 读卡器和卡 J3A081。

编辑

经过几个小时的尝试，我设法实现了一些目标。首先，我更新了一个ACR122U智能卡读写器的驱动。此外，我熟悉了 GPSshell 并创建了一个简单的脚本:

mode_211
enable_trace
establish_context
card_connect
select -AID a000000003000000
open_sc -security 1 -keyind 0 -keyver 0 -mac_key 404142434445464748494a4b4c4d4e4f -enc_key 404142434445464748494a4b4c4d4e4f   
card_disconnect
release_context

哪些输出:

所以我想一切正常，但是当我想使用这个安装小程序时:

mode_211
enable_trace
establish_context
card_connect
select -AID a000000003000000
open_sc -security 1 -keyind 0 -keyver 0 -mac_key 404142434445464748494a4b4c4d4e4f -enc_key 404142434445464748494a4b4c4d4e4f
install -file helloworld.cap -nvDataLimit 2000 -instParam 00 -priv 2
card_disconnect
release_context

我有一个异常(exception):

mode_211
enable_trace
establish_context
card_connect
select -AID a000000003000000

谁能得到类似的错误？你知道这意味着什么吗？

编辑 2我终于设法在我的卡上安装了小程序。我使用修改过的 GlobalPlatformPro，如 vlp 所写，有必要将加载 block 更改为 16 字节。

但我只能安装 hello world applet，在处理我的过程中，GlobalPlatformPro 返回异常:

java -jar gp_16byteLoadBlock.jar --install inzynierka.cap
pro.javacard.gp.GPException: LOAD failed SW: 6A80
        at pro.javacard.gp.GlobalPlatform.check(GlobalPlatform.java:1092)

        at pro.javacard.gp.GlobalPlatform.loadCapFile(GlobalPlatform.java:686)
        at pro.javacard.gp.GPTool.main(GPTool.java:453)

最佳答案

(评论中的讨论记录)

事实证明，ACR122U NFC 读卡器存在长 APDU 的问题(也提到了 here)。

一种可能的解决方案是修改 GlobalPlatformPro通过以下方式使用工具:

  • 获取资源 here

  • 在 GlobalPlatform.java:724 找到检索加载文件 block 的代码部分

  • 通过用一些更小的常量替换 wrapper.getBlockSize() 部分来减小加载 block 大小(32 已确认工作并且 64 已确认不适用于此阅读器)

  • 重新编译 GlobalPlatformPro

编辑>

最新的GlobalPlatformPro代码adds -bs 选项，允许您设置 block 大小而无需重新编译。
