摘要随着我国信息化的发展，电子贸易在商务越来越普遍。随即智能卡的安全系统成为了研究的重中之重。本文是在公钥体系结构的基础上，设计一个具有可靠性高、方便快捷等特点的电子钱包。要求能够完成用户在电子交易方面的一般需求。从卡的一般结构到工作原理开始分析，逐步探索。在了解智能卡密钥系统的前提下设计一个能够完成用户消费、圈存、查询等要求的电子钱包系统。65900

本文研究的是智能卡的工作原理和安全技术等方面的理论，探索基于MIFARE卡的电子钱包的实用性和公平性。模拟出电子钱包的的基本工作过程，实现简易的电子钱包模型。从实际出发，在满足用户基本需求的角度，完成一个计算能力低和小存储量的硬件MIFARE卡

课题研究的主要方向：

1. 卡片的结构设计；

2. MIFARE卡的密钥系统；

3. 读写卡程序设计；

本文首先介绍了智能卡的软硬件知识、智能卡的内部结构、文件组织及一些关键操作；其次运用德卡D8读卡器分析和设计了基于MIFARE卡的电子钱包的文件系统，并对其中的密钥管理和电子钱包的充值与消费流程进行了重点的分析；最后使用MFC实现了口令密钥的验证，电子钱包的充值，查询和消费功能。

    本文设计的基于CPU卡的电子钱包实现了电子钱包的基本功能，满足了用户的对与电子钱包的安全使用。

Abstract

With the development of information technology, e-commerce is increasingly common in the business. Then the smart card security system has become a research priority. This article is based on a public key architecture, design a high reliability, convenient features such as electronic wallets. Requires the user to be able to complete the general requirements to electronic trading. The general structure from the card to begin analyzing the working principle, and gradually explore. Smart card key in understanding the premise of designing a system to complete user consumption, Quancun, inquiries and other requirements of the electronic purse system.

This study is the working principle and smart card security technology and other aspects of the theory, exploring MIFARE card based electronic purse practicality and fairness. Simulate the electronic purse of the basic work processes, to achieve simple model of an electronic wallet. From reality, to meet the basic needs of the user's perspective, the completion of a low computing power and small storage hardware MIFARE card.

Main directions of research:

1. card design;

2. MIFARE card key system;

3. read card programming;

This paper introduces the knowledge of smart card hardware and software, smart card, the internal structure, file organization and some of the key operations; followed  by the use of de D8 reader analysis and design of the MAFARE card based electronic  purse of the file system, and one of the key Top-management and e-purse and consumption processes were focused analysis; 

finally achieved using MFC password key authentication, the rechargeable electronic wallet, query, and consumer spending.

This MAFARE card based on the design of electronic wallet to achieve the basic functions of electronic wallet, to meet the users on the safe use and electronic purse.

Keywords: smart card; card structure; electronic wallet ;MIFARE card;
