讀取JavaCard Classic上的TLV編碼數據

Question

我想閱讀Java卡上的TLV編碼證書（恩智浦JCOP J3D081，JCOP版本2.4.2，Java卡版本3.0.1經典版）。

帽文件創建成功，但是當我嘗試在卡上安裝它，我得到一個錯誤gpshell：

load() returns 0x80206A80 (6A80: Wrong data/Incorrect values in command data.)

我使用JCDK 3.0.3的罐子，這通常與東西就像橢圓曲線等等。TLV的東西有什麼不同？

使用的applet代碼（不使用BERTLV的東西時，安裝精細）：

package org.thomas; 

import javacard.framework.APDU; 
import javacard.framework.Applet; 
import javacard.framework.ISO7816; 
import javacard.framework.ISOException; 
import javacard.framework.Util; 
import javacardx.framework.tlv.BERTLV; 
import javacardx.framework.tlv.ConstructedBERTLV; 

public class TlvApplet extends Applet { 

    private ConstructedBERTLV certificate; 
    byte[] certificateLength = new byte[2]; 

    /** 
    * TlvApplet constructor 
    * 
    * @constructor 
    */ 
    private TlvApplet() { 

     // Register with the JCRE 
     register(); 
    } 

    /** 
    * Installs 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 TlvApplet(); 
    } 

    public void process(APDU apdu) throws ISOException { 

     byte buffer[] = apdu.getBuffer(); 
     short incomingLength = apdu.setIncomingAndReceive(); 

     certificate = (ConstructedBERTLV) BERTLV.getInstance(buffer, 
      ISO7816.OFFSET_CDATA, incomingLength); 


     certificateLength[0] = (byte) (certificate.size() & 0xff); 
     certificateLength[1] = (byte) ((certificate.size() >> 8) & 0xff); 

     Util.arrayCopyNonAtomic(certificateLength, (short) 0, buffer, 
      ISO7816.OFFSET_CDATA, (short) 2); 

    } 

} 

我用下面的螞蟻的build.xml創建CAP文件：

<?xml version="1.0" encoding="UTF-8" ?> 
<project default="convert" name="Create JC 3 applet" basedir="."> 
<property environment="env" /> 

<!-- Include properties in the build.properties file -->

構建。使用的屬性：

# Source folder 
source.folder     = src/org/thomas 

# Java Card Development Kit folders 
jcdk.basefolder     = lib/javaCardKit303 
jcdk.subfolder.apiexportfiles = api_export_files 
jcdk.subfolder.libs    = lib 

# Target folders (will be created, no need to adapt) 
target.basefolder    = target 
target.subfolder.classes  = classes 
target.subfolder.applet   = applet 

# Applet properties 
package.aid  = 0x41:0x41:0x41:0x41:0x41:0x41:0x41:0x41:0x41:0x42 
package.name = org.thomas 

applet.aid  = 0x41:0x41:0x41:0x41:0x41:0x41:0x41:0x41:0x41:0x42:0x42 
applet.name  = TlvApplet 
applet.version = 1.0 

# Java class compiler options 
javac.debug    = no 
javac.optimize   = no 
javac.version.source = 1.5 
javac.version.target = 1.5 


# CAP file creation options 
cap.creation.verbose = false 
cap.creation.noverify = false 
cap.creation.debug  = false 
cap.creation.jca  = false 
cap.creation.exp  = false 

所以懷疑cap是用api_connected.jar編譯的，但是remo從套件中取出文件，沒有改變任何東西。

任何幫助，將不勝感激。在此先感謝，托馬斯

該卡根本不支持java卡API的TLV類。 JC API只是一個建議，但卡製造商可能會選擇實施它的一個子集。

一般來說，javacardx中的任何內容都是可選的（因此末尾的x）。 javacard中的API方法必須實現。即使對於javacard包和類，並不是所有功能都可能在運行時可用。例如，密碼算法可能不存在。
