IC卡应用系统开发-(一)卡片读写

IC卡应用系统开发-(一)卡片读写
最近在开发一个基于CPU卡应用的J2EE项目,应用服务器用的是Weblogic,数据库是oracle, 开发工具jbuilder2005.系统架构是:客户端(pc/sc读写器)客户端首先要安装IC读写器驱动(必须支持PC/SC规范),然后到pcscworkgroup网站下载文件installOCF.class和Reference_Impl.class.
运行>java installOCF
按照提示一步一步进行安装操作.
运行>java Reference_Impl
默认安装操作.
在安装完后将thirdpartyOCF1.2libOCFPCSC1.DLL和thirdpartyOCF1.2libOCFPCSCM.DLL拷贝到jdk的bin目录.
在jbuilder工程文件目录下建立opencard.properties文件,内容如下,
# Configure the CardService Registry:
# Use the service factory for the IBM MultiFunction Cards
OpenCard.services = opencard.opt.util.PassThruCardServiceFactory
#OpenCard.services = com.ibm.opencard.factory.MFCCardServiceFactory
# OpenCard.services = com.slb.opencard.CyberflexAccess.CyberflexAccessCardServiceFactory

# Configure the CardTerminal Registry:
com.ibm.opencard.terminal.pcscmig.PcscMigCardTerminalFactory
OpenCard.terminals = com.ibm.opencard.terminal.pcsc10.Pcsc10CardTerminalFactory

# Configure Tracing. Detailed for all samples only:
OpenCard.trace = opencard:8

在jbuilder中建立pcsc库.
tools-->configure-->libraries
在user home下建立pcsc10,在required libraries选项卡中选择安装的目录下lib下的所有文件.
我用的读写期是某公司的,命令集与PBOC稍有改动,但基本格式是按照PCSC的.
我建立了3个文件:
接口文件:IReader.java,用于程序将来兼容其他读写器;
实现文件:ReaderMA,java,实现接口,
异常文件:ReaderException,用户捕获异常及错误处理.
实现文件如下:
package com.microapp.application.reader;

用opencard规范开发非常的简单,特别是处理返回数据,在responseAPDU内用sw1和sw22个方法用于返回sw1,sw2.数据是直接用response.data()即可.省缺了一般读写拼字节的过程.

在读写器之上我定义了一个基于应用的卡片类,AppCard,在这个类内实现卡片的具体操作.
如内部认证,外部认证,获取随机数等.

public void reset() throws TicketException
{
try
{
byte[] batr = reader.Reset();
StringBuffer sb = new StringBuffer();
String s = new String();

for(int i = 0; i < batr.length; i++)
{
s = Integer.toHexString(batr[i]).toUpperCase();
if(s.length() == 1)
{
sb.append("0" + s);
}
else if(s.length() > 2)
{
sb.append(s.substring(s.length() - 2, s.length()));
}
else
{
sb.append(s);
}
sb.append(" ");
}

atr = sb.toString();
}
catch(ReaderPCSCException rex)
{
throw new TicketException("Reset failed! " + rex.getMessage());
}
}

/**

*/
public void ShutDown() throws TicketException
{
try
{
reader.ShutDown();
}
catch(ReaderException ex)
{
throw new TicketException("Shutdown failed!");
}
}

/**
* 获取随机数
* @return String
*/
public String getChallenge() throws TicketException
{
try
{
StringBuffer sb = new StringBuffer();
String s = new String();
byte[] buf = reader.getChallenge();

for(int i = 0; i < buf.length; i++)
{
s = Integer.toHexString(buf[i]).toUpperCase();
if(s.length() == 1)
{
sb.append("0" + s);
}
else if(s.length() > 2)
{
sb.append(s.substring(s.length() - 2, s.length()));
}
else
{
sb.append(s);
}
}

return sb.toString();
}
catch(ReaderPCSCException rex)
{
throw new TicketException(rex.getMessage());
}
}

/**

*/
public String IntenalAuthentication(String data) throws TicketException
{
try
{
byte[] sendbuf = new byte[8];
sendbuf[0] = (byte)(Integer.parseInt(data.substring(0,2), 16));
sendbuf[1] = (byte)(Integer.parseInt(data.substring(2,4), 16));

for(int i = 0; i < recvbuf.length; i++)
{
s = Integer.toHexString(recvbuf[i]).toUpperCase();
if(s.length() == 1)
{
sb.append("0" + s);
}
else if(s.length() > 2)
{
sb.append(s.substring(s.length() - 2, s.length()));
}
else
{
sb.append(s);
}
}

return sb.toString();
}
catch(ReaderPCSCException rex)
{
throw new TicketException(rex.getMessage());
}
catch(NumberFormatException ex)
{
throw new TicketException(ex.getMessage());
}
catch(IndexOutOfBoundsException ex)
{
throw new TicketException(ex.getMessage());
}
}

/**

public boolean ExternalAuthentication(String data) throws TicketException
{
try
{

buf[1] = (byte)(Integer.parseInt(data.substring(2,4), 16));
buf[2] = (byte)(Integer.parseInt(data.substring(4,6), 16));
buf[3] = (byte)(Integer.parseInt(data.substring(6,8), 16));
buf[4] = (byte)(Integer.parseInt(data.substring(8,10), 16));
buf[5] = (byte)(Integer.parseInt(data.substring(10,12), 16));
buf[6] = (byte)(Integer.parseInt(data.substring(12,14), 16));
buf[7] = (byte)(Integer.parseInt(data.substring(14,16), 16));

return reader.ExternalAuthentication(buf);
}
catch(ReaderPCSCException rex)
{
throw new TicketException(rex.getMessage());
}
catch(NumberFormatException ex)
{
throw new TicketException(ex.getMessage());
}
catch(IndexOutOfBoundsException ex)
{
throw new TicketException(ex.getMessage());
}
}
利用该方法,在客户端实现了用户卡的读写,大大简化了开发,并运行稳定,性能完全预期要求.
