PROJECT TITLE :

GeTrust: A Guarantee-Based Trust Model in Chord-Based P2P Networks - 2018

ABSTRACT:

Additional and additional users are attracted by P2P networks characterised by decentralization, autonomy and anonymity. However, users' unconstrained behavior makes it necessary to use a trust model when establishing trust relationships between peers. Most existing trust models are primarily based on recommendations, which, however, suffer from the shortcomings of slow convergence and high complexity of trust computations, furthermore huge overhead of network traffic. Inspired by the establishment of trust relationships in human society, a guarantee-based trust model, GeTrust, is proposed for Chord-based mostly P2P networks. A service peer wants to decide on its guarantee peer(s) for the service it's going to provide, and they're both needed to pledge name mortgages for the service. The request peer makes evaluations on all the candidates of service peer by referring their service reputations and their guarantee peers' reputations, and selects the one with highest analysis to be its service provider. In order to boost GeTrust's availability and prevent malicious behavior, we conjointly present incentive mechanism and anonymous reputation management strategy. Simulation results show that GeTrust is effective and efficient in terms of improving successful transaction rate, resisting complex attacks, reducing network overhead and lowering computational complexity.
