【中文标题】T=0 JavaCards 的传输错误【英文标题】：Transmission error for T=0 JavaCards 【发布时间】：2016-01-25 06:41:36 【问题描述】：

我有 4 种不同类型的 JavaCard。出于一个奇怪的目的，我编写了以下小程序以在接收到每个 APDU 命令时返回整个 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：

T=0 卡有什么问题？

【问题讨论】：

【参考方案1】：

您的卡没有问题。实际上，三张“T=0”牌的反应是“预期的”。而是返回意外结果的“T=1”卡/JCOP。

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，但不存在 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，您永远不应该为此类命令调用 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*() 可能会导致意外/错误行为：

该方法只能在 case 2 或 case 4 命令上调用，否则可能导致错误行为。

因此，您应该始终检查您拥有的命令案例，并仅在适当的时候接收/响应数据（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预期内容）。

为什么 case-1 APDU 像您所期望的那样工作（即返回响应数据字段）与 T=0 TPDU 的格式以及 APDU 映射该格式的方式有关。 T=0 TPDU 的格式为

CLA INS P1 P2 P3 [DATA]

P3 字段始终存在，而 DATA 字段仅存在于 case-3 APDU 中。应用了以下 TPDU 和 APDU 之间的映射：

Case-4 APDU：T=0 不直接支持（阅读器通常将此映射到 case-3 + GET RESPONSE 命令） 案例 3 APDU：P3 = Lc，DATA = DATA 案例 2 APDU：P3 = Le，DATA = 缺席 案例 1 APDU：P3 = 0，DATA = 不存在

如您所见，对于 case-1 APDU，P3 字段用零填充。这意味着卡无法区分 Le = 0 的 case-2 APDU 和 case-1 APDU。因此，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）。
