中邮储IC卡系统改造工程数据准备子系统摘要金融IC卡应用工程是防范银行卡风险，推动产业升级，提升金融服务，促进政府管理，惠及人民群众的一项重大社会工程。在2005年3月中国人民银行发布了《中国金融集成电路（IC）卡规范》（PBOC2.0），并在北京、上海、天津、青岛、福州等地开始试点工作。2006年，央行又进一步完善了我国银行IC卡发展规划，鼓励商业银行发行基于电子钱包功能的IC卡。本文首先分析了国内外银行IC卡的发展现状和存在的问题，然后介绍了一种现在国内外正在研究开发的基于IC、磁条合一的卡产品——金融IC卡。在此基础上，设计了这套金融IC卡系统。设计内容主要包括IC卡前置子系统、数据准备子系统、IC卡管理子系统、渠道接入子系统、后台接入子系统、监控子系统、数据清理子系统及IC卡安全子系统。本论文主要讨论的是数据准备子系统。该子系统利用了某公司TopSmartTeller开发工具，具有灵活、方便、易于维护的特点。主体设计部分基于Linux平台，采用C语言、ProC和Oracle数据库，主要实现数据的接收、数据的处理和生成制卡文件三大核心需求。本论文主要解决以下问题：1.对从第三方(安全中心)发来的证书文件的解密及生成制卡文件后的加密。2.定义发卡模板及套用发卡模板进行业务参数的填充。3.转换后生成IC卡制卡文件。关键词：IC卡，数据处理，制卡文件2China'sPostalSavingsBankICCardSystemRenovationDataPreparationSubsystemAbstractFinancialICcardapplicationbankcardprojectisanimportantsocialprojectwhichcanpreventrisks,promoteindustrialupgrading,enhancefinancialservices,promotegovernanceandbenefitpeople.People'sBankofChinapromulgatedtheChinafinancialintegratedcircuit(IC)CardSpecification(PBOC2.0)inMarch2005andbegantomakeexperimentsinBeijing,Shanghai,Tianjin,QingdaoandFuzhou.ThecentralbankimproveddevelopmentprogramofICcardinBankofChinaandencouragedcommercialbankstopublishICCardbasedonelectronicpursefunctions.ThisarticleanalyzesthedevelopmentofdomesticandforeignbanksICcardstatusandexistingproblems,andthenintroducedthefinancialICcardbasedonICandmagneticstripewhichisresearchedanddevelopedathomeandabroad.AfinancialICcardsystemisdesignedonthisbasis.Thisdesignincludespre-subsystem,datapreparationsubsystem,ICcardmanagementsubsystem,thechannelaccesssubsystem,backstageaccesssubsystem,controlsubsystem,datacleaningsubsystemandsecuritysubsystem.Thisessayfocusesonthedatapreparationsubsystem.DatapreparationsubsystemisdevelopedbyTopSmartTellerwhichisflexible,convenientandmaintainable.Thekeypartofthisdesign,whichisbasedonLinux,Clanguage,ProCandOracleDatabase,realizesdatareception,dataprocessingandcard-creatingfilesgenerating.Theproblemssettledinthisthesisareasfollowing:Decryptcertificatefromthethirdpart(SecurityCenter)andencryptcard-creatingfiles.2.Definecardtemplatesanddoparametersfillingaccordingtothiscardtemplates.3.Generatecard-creatingfilesafterconversion.Keywords:ICcard，DataProcessing，CardFileSystem3目录1绪论...............................................................................................................................................41.1项目来源.............................................................................................................................41.2项目背景.............................................................................................................................41.3国内外在该方向的研究现状及分析.................................................................................51.4使用的开发平台.................................................................................................................52基础知识........................................................................................................................................72.1数据加密算法.....................................................................................................................72.2认证中心.............................................................................................................................72.3数据完整性.........................................................................................................................73系统的分析与设计........................................................................................................................83.1系统边界设计.....................................................................................................................83.1.1本系统定位......................................................................................................................83.1.2系统关联试图..................................................................................................................93.2网络拓扑图.........................................................................................................................93.3系统数据流图...................................................................................................................103.4应用架构设计...................................................................................................................113.4.1应用架构设计概述........................................................................................................113.4.2逻辑架构........................................................................................................................113.4.3功能需求与系统模块对应关系....................................................................................123.5IC卡数据准备子系统的功能模块设计..........................................................................123.5.1逻辑结构........................................................................................................................123.5.2处理流程........................................................................................................................133.5.3运行设计..................................................................
