T=0 JavaCards 的传输错误

Question

我有 4 种不同类型的 JavaCards。出于一个奇怪的目的，我编写了以下小程序 return 在接收到每个 APDU 命令时整个 APDU 缓冲区：

package bufferReturner;

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

public class BufferReturner extends Applet {

    private BufferReturner() {
    }

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

    }

    public void process(APDU arg0) throws ISOException {
        arg0.setOutgoingAndSend((short)0, (short)256);
    }

}

当我向我的卡发送 APDU 命令时，我得到以下结果：

NXP JCOP v2.4.2 r3 卡 - 使用 T=1

T=0 卡有什么问题？

Answer 1

你的卡没有问题。实际上，三张 "T=0" 卡片响应为 "expected"。而是 "T=1" 卡/JCOP returns 出乎意料的结果。

您正在发送以下 APDU：

00A404000B0102030405060708090101
00000000
00000000020101

第一个和第三个是 case-3 APDU（Lc 和命令 DATA 字段存在，Le 字段不存在）。第二个 APDU 是 case-1 APDU（只有命令头，但没有 Lc、DATA 和 LE 字段）。因此，所有三个 APDU 都清楚地表明不应返回任何响应数据字段。因此，您永远不应为此类命令调用 setOutgoing*() 方法。请注意，Java Card API 规范对此非常清楚，并明确指出在 case-1/case-3 命令上调用 setOutgoing*() 可能会导致 unexpected/wrong 行为：

This method should only be called on a case 2 or case 4 command, otherwise erroneous behavior may result.

因此，您应该始终检查您拥有的命令案例，并在适当时只检查 receive/respond 数据（您通常可以根据指令代码确定这一点，因为您知道每条指令的期望值).

为什么 case-1 APDU 像你期望的那样工作（即 returns 响应数据字段）与 T=0 TPDU 的格式和APDU 映射该格式的方式。 T=0 TPDU 的格式为

CLA INS P1 P2 P3 [DATA]

P3 字段始终存在，而 DATA 字段仅在 case-3 APDU 中存在。应用了 TPDU 和 APDU 之间的以下映射：

Case-4 APDU：T=0 不直接支持（reader 通常将其映射到 case-3 + GET RESPONSE 命令）
案例 3 APDU：P3 = Lc，数据 = 数据
案例 2 APDU：P3 = Le，数据 = 不存在
案例 1 APDU：P3 = 0，数据 = 不存在

如您所见，对于 case-1 APDU，P3 字段填充为零。这意味着卡无法区分 Le = 0 的 case-2 APDU 和 case-1 APDU。结果，当 T=0 时，任何 case-1 APDU 都将被视为 case-2 APDU。因此，setOutgoingAndSend() 方法将适用于 case-1 APDU（在您的情况下为 00000000）。
