“…To prevent normal peers from being harmed by malicious peer behaviors, reputation systems serve for peers to assess the trustworthiness of others and to selectively interact with more reputable ones. Identifying trustworthy peers is especially necessary in commercial P2P applications, such as P2P auctions [6], pay-per-transaction [7], and P2P service discovery [8].…”

SUMMARY The anonymity and dynamic character of a Peer‐to‐Peer (P2P) network makes it an ideal medium for selfish and vicious action. In order to solve this problem, P2P reputation systems are proposed to evaluate the trustworthiness of peers and to prevent the selfish, dishonest, and malicious peers' behaviors, which collects local reputation scores and aggregates them into the global reputation. In this paper we propose a DHT (Distributed Hash Table) trust overlay network (DHTON) to model the network structure and the storage of reputation information. We also design a robust and distributing reputation system, DHTrust, which takes full advantage of the DHT to distribute local reputation to trade‐off the damage of fake reputation information by genuine reputation information. By using the trust evaluation towards two reputation scores, we can also distinguish and evaluate the fundamental behaviors of peers in the P2P network, i.e. providing service and issuing reputation scores. To adapt to the dynamic P2P networks, we take dynamic node mechanism into account. Our scheme can assure convergence effectiveness and robustness, when nodes enter or leave the system. We conduct extensive simulations to evaluate the performance of DHTrust. The results show that our system makes significant improvement in convergence speed and aggregation accuracy. Moreover, it is robust to malicious peers. Copyright © 2011 John Wiley & Sons, Ltd.

“…If users contribute fewer efficitive resources, the total amount of public resources will be reduced;if users contribute more resources, many resources are likely to be invalid, or even worthless resources, and this may waste system storage resources.Thus,we present resource auction incentive mechanism system, system incent peers to contribute effective resource through auction economic pattern [2]. Due to the dynamic nature of moving hosts,we allocate resource depending on the reputation of moving node, the higher reputation nodes have the priority to gain the resource,because they have much virtual currencies to compete,who give the most virtual currencies to seed may have the fastest downing speed.This incentive mechanism induced users to share the resource , who contribute more resources may gain virtual currencies from system and improve the reputation,it can have higher competitive in next competition.…”
