Research on single-domain multi-factor trust model in P2P system

摘要

In order to resolve the problems in P2P system, such as security, bad management and single computation of trust value in current trust model, a domain-based multi-factor trust model in P2P system is proposed. This model is based on the hybrid P2P network structure, calculates trust value of nodes by using multi-factor. The data model and the way of trust value calculation are proposed. The simulation proves that this model can isolate and identify malicious peers efficiently, with high performance of security.
