چکیده
Providing an effective accounting scheme for decentralized peer-to-peer systems is difficult without relying on a central server or peers with special trusted status. In this paper, we present Probabilistic Quorum-based Accounting (PQA) for peer-to-peer systems. In our approach, a peer receiving a request will retrieve resource usage accounting information about the requesting peer from a quorum of peers to determine whether or not to grant the request. Our solution is completely decentralized and does not require a special trusted status for any peers.

Trusted accounting in peer-to-peer environments: a novel token-based accounting scheme for autonomous distributed systems
Communication systems based on the peer-to-peer (p2p) paradigm present what is likely the most important development in Internet technology in recent years. In spite of the position of p2p systems as the largest source of traffic on the Internet, their commercial success is still limited. The basic tenets of p2p systems are cooperation among peers and completely decentralised communication. How...
متن کاملA Genetic Programming-based trust model for P2P Networks
Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

متن کاملA Secure Quorum Based Membership Mechanism for P2P Systems
Closed user group based on a Peer-to-Peer system require a membership mechanism that is fully decentralized. Several suggestions have been made in the literature. However, the proposed mechanisms have some significant drawbacks since any peer can easily bypass the proposed membership mechanism. In this paper we present a new fully decentralized and secure membership mechanism for Peer-to-Peer s...
متن کاملDoes Proactive Secret Sharing Perform in Peer-to-Peer Systems?
Trustworthy applications in fully decentralized systems require a trust anchor. This paper describes how such an anchor can be implemented efficiently in p2p systems. The basic concept is to use threshold cryptography in order to sign messages by a quorum of peers. The focus is put on advanced mechanisms to secure the shares of the secret key over time, using proactive secret sharing. This mech...
