| Abstract: | Free-riding and some malicious actions have hampered development of Peer-to-Peer(P2P) network. This paper proposes a peer reputation audit and evaluation algorithm which is based on peer transaction records and improves exist trust evaluation model. The audit and evaluation algorithm employs incentive mechanism to restrain free-riding, employ digital signature and audit to restrain diversified malicious action. Simulation experimentsal results show that the algorithm is efficient and practicality. |
