基于智能卡的远程文件安全管理系统设计和开发

Design and Development of Remote File Management System Based on Smart Card

网络存储业务现已成为人们日常生活中不可或缺的一环,但是,目前的账户/密码模式无法很好保证文件的安全性。因此,文章利用智能卡的物理安全特性,设计了一种新型的远程文件安全管理系统。文章制定了一种基于智能卡的文件加密方案,并设计了一种通信协议以支持多个用户同时进行文件管理。系统内的用户必须使用各自经过授权的智能卡进行登录及身份验证,并可对后续的通信内容进行加密,从而避免了文件信息被恶意窃取或篡改。

The network storage service is essential in our life now. However, the password o f anaccount canJt guarantee the security completely. Therefore, a client o f the remote file managementsystem is designed, w hich is based on the physical security o f smart cards. In this paper, a fileencryption scheme is developed based on smart cards in order to protect the file itself. A t the sametime,a communication protocol is designed to enable many users to manage their files. In this case,every user can login the system w ith their authorized smart card, w hich protects the communicationand files.
