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
