Research of P2P Trust based on Fuzzy Decision-making

Fuzzy logic offers the ability to handle uncertainty and imprecision effectively, and is therefore ideally suited to reasoning about trust in P2P environment. A new P2P fuzzy trust model is presented in this paper. Because trust-based P2P computing network is very similar to the interpersonal relationship network, this fuzzy trust model includes two phases: recommendation trust phase and direct trust phase. Recommendation trust phase mainly focuses on extraction of trust link and calculation of recommendation trust degree based on fuzzy decision-making method. Fuzzy trust evaluation result will be obtained according to various factor sets and evaluation sets based on fuzzy decision-making method. Direct trust phase mainly focuses on updating of direct trust degree.
