Dynamic policy based model for evolution of trust in P2P applications
نویسنده
چکیده
The decentralized and anonymous characteristics of P2P environments, necessitates the need for an access control model, based on trust and recommendation. Since peers are heterogeneous, some peers might be malicious and in the absence of a centralized authority to punish such peers, mechanisms for trust and recommendation can help to distinguish between good and bad peers. In this paper we propose a dynamic multi-level access control framework for P2P applications which integrates policy based access control with trust based access control. We use a prolog like language to model the dynamic access control policies.

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
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 کاملGGRA: a grouped gossip-based reputation aggregation algorithm
An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...
