摘要：

We propose and implement a flexible secure file sharing scheme which can be used for data sharing among members in P2P environment When a member wants to share data, notification messages are sent to the members with whom the member wants to share data Each notification message includes one-time password encrypted with the receiver's public keys A member who received the notification message can download the data by using the one-time pass-word The proposed scheme provides selective sharing, download confirmation and efficient memory management In terms of security the proposed scheme supports authentication, entity, privacy replay attack protection and disguise prevention We also implement the proposed system and find that the system is very useful among P2P service of closed user groups.
