摘      要：正This paper introduces R2P,a Peer-to-Peer（P2P） transfer system with role based and reputation based access control *** the combination of user authentication,organization authorization and scoring system,we solve the problem of resource piracy,user privacy and network jam,which exist in traditional P2P *** R2P system takes advantage of the X509 certificate to implement the role based access control *** assembling the artificial scoring and the automatic scoring components,the system evaluates the quantity and quality of the transfer resources,putting forward the reputation based access control *** the two policies and the adaptive P2P transfer model,the R2P system provides a secure, controllable and efficient resource transfer community.
