Abstract
Peer-to-peer (P2P) is a communications model in which each party has the same capabilities and either party can initiate a communication session. Other models with which it might be contrasted include the client/server model and the master/slave model. P2P file sharing has been a major P2P application, and enables peers to distribute, search, and retrieve files collaboratively. Although P2P file sharing systems offer scalable and self-organized file services with wide availability and good stability, but the decentralized nature make them inherently difficult to control the distribution of shared files. In this thesis, a distribution control system is proposed to restrict the sharing of files to the peers who qualified the constraints associated with the files. Peers are responsible to gauge requesting peers’ qualifications for the files they are holding, and evaluation results are encapsulated in credentials signed and exchanged in the process. Credentials are collected and presented by peers as evidence of qualifications.
