摘要:

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。

关键词: 智能卡, 远程文件管理, 文件加密, 通信协议

Abstract:

The network storage service is essential in our life now. However, the password of an account can’t guarantee the security completely. Therefore, a client of the remote file management system is designed, which is based on the physical security of smart cards. In this paper, a file encryption scheme is developed based on smart cards in order to protect the file itself. At the same time,a communication protocol is designed to enable many users to manage their files. In this case, every user can login the system with their authorized smart card, which protects the communication and files.

Key words: smart card, remote file management, file encryption, communication protocol
