ubuntu/Mac系统智能卡操作全攻略1--访问PC/SC读卡器

因为PC/SC是Windows的体系，以系统API的层面服务应用。所以一直以来智能卡相关的读卡器和工具都集中在Windows上，而在unix体系下则一直水土不服。值得庆幸的是随着开源组织M.U.S.C.L.E (Movment for the Use of Smart in Linux Environment)的积极努力下，pcsclite作为Xnix下的PC/SC设备框架和应用接口已经成为了事实上的标准，Mac的Lion系统更是已经在发行版里面集成了此服务。下面以ubuntu 12.0.4 发行版为例子。

#首先安装pcsc的守护进程pcscd和工具

sudo apt-get -y install libusb-dev

sudo apt-get -y install pcscd

#然后安装支持pcsc的读卡器驱动（例子为内置的ACR ACS38U，其它读卡器也可以到网站下载安装)

sudo apt-get -y install libacr38u

#连接读卡器，插卡后运行扫描工具验证安装结果

pcsc_scan

结果如下：

Your card is not present in the database.
You can get the latest version of the database from
http://ludovic.rousseau.free.fr/softwares/pcsc-tools/smartcard_list.txt
or use: wget http://ludovic.rousseau.free.fr/softwares/pcsc-tools/smartcard_list.txt --output-document=/home/caesarzou/.smartcard_list.txt


If your ATR is still not in the latest version then please send a mail

#到此为止，PC/SC驱动已经打通，现在我们试试发个APDU

sudo apt-get -y install pcsc-tools

gscriptor

这是一个图形界面的工具，在Script框里面输入:

00A4040000

点Run按钮，可以看到连接提示，然后就是结果：

Beginning script execution...

#恭喜你，卡片访问成功，现在你一定心痒难耐，想创建你自己的应用了吧？

#安装开发库

sudo apt-get install libpcsclite-dev

#安装eclipse的cdt作为开发环境

sudo apt-get -y install g++
sudo apt-get -y install eclipse eclipse-cdt

#打开eclipse，新建一个C工程，在c文件中加入

#include <PCSC/winscard.h>

#链接到pcsclite库：在C/C++ build / GCC Linker / Libraries 增加 pcsclite

#现在你会幸福的发现，winscard.h里面提供的类型定义和接口和windows是一致的，我们从windows中拷贝一段代码过来：

#include <stdio.h>#include <PCSC/winscard.h>int main(void) {SCARDCONTEXT m_hContext;SCARDHANDLE  m_hCard;SCARD_IO_REQUEST io;char pmszReaders[100];BYTE CAPDU[] = {0x00,0xA4,0x04,0x00,0x00};BYTE RAPDU[256+2];DWORD cch = 100;DWORD i = 0;//Insertif(SCARD_S_SUCCESS != SCardEstablishContext(SCARD_SCOPE_USER, NULL, NULL, &m_hContext)){printf("Context error");return -1;}//List Readerif(SCARD_S_SUCCESS != SCardListReaders(m_hContext, NULL, pmszReaders, &cch)){printf("List Reader error");return -2;}printf("List Readers\n");while(i<cch){printf("%s\n",pmszReaders+i);i += strlen(pmszReaders);i ++;}//Connect first Readerio.cbPciLength = sizeof(SCARD_IO_REQUEST);if(SCARD_S_SUCCESS != SCardConnect(m_hContext, pmszReaders, SCARD_SHARE_SHARED, SCARD_PROTOCOL_T0|SCARD_PROTOCOL_T1, &m_hCard, &io.dwProtocol)){printf("Connect Card error");return -3;}//Transmit APDUcch = 256+2;if(SCARD_S_SUCCESS != SCardTransmit(m_hCard, &io, CAPDU, 5, NULL, RAPDU, &cch)){printf("Transmit APDU error");return -4;}//echoprintf("Transmit APDU\n");printf("CAPDU: ");for(i=0;i<5;i++){sprintf(pmszReaders,"%02X",CAPDU[i]);printf("%s",pmszReaders);}printf("\n");printf("RAPDU: ");for(i=0;i<cch;i++){sprintf(pmszReaders,"%02X",RAPDU[i]);printf("%s",pmszReaders);}printf("\n");//DisConnectSCardDisconnect(m_hCard, SCARD_EJECT_CARD);//EjectSCardReleaseContext(m_hContext);//puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */return 0;}

#编译运行，输出：
List Readers
ACS ACR38U 00 00


Transmit APDU
CAPDU: 00A4040000
RAPDU: 6C12

大功告成！下一个攻略我会讲一下在ubuntu上基于JavaCard环境和工具的配置，敬请期待。

注：

ubuntu上libpcsclite的头文件默认位置在/usr/include/PCSC中，多了个目录，有的版本在编译的时候可能有#include 文件错误，可以自行修改如下：

sudo vim /usr/include/PCSC/winscard.h

将#include <pcsclite.h>修改为#include <PCSC/pcsclite>，保存退出

sudo vim /usr/include/PCSC/pcsclite.h

将#include <wintypes.h>修改为#include <PCSC/wintypes.h>，保存推出
