An exhaustive survey of trust models in p2p network
It addresses soft security issues in P2P networks for users and researchers, but is incremental as it surveys existing models without proposing new solutions.
The paper presents a comprehensive survey of trust and reputation models in P2P networks, focusing on service provisioning, and identifies key challenges such as trust bootstrapping and classification of peer behaviors.
Most of the peers accessing the services are under the assumption that the service accessed in a P2P network is utmost secured. By means of prevailing hard security mechanisms, security goals like authentication, authorization, privacy, non repudiation of services and other hard security issues are resolved. But these mechanisms fail to provide soft security. An exhaustive survey of existing trust and reputation models in P2P network regarding service provisioning is presented and challenges are listed.p2p Trust issues like trust bootstrapping, trust evidence procurement, trust assessment, trust interaction outcome evaluation and other trust based classification of peers behaviour into trusted, inconsistent, un trusted, malicious, betraying, redemptive are discussed.
