Abstract—The trust value based on fuzzy comprehensive evaluation fluctuates remarkably. Aiming at this problem, this paper establishes membership function of trusted set, according to the trusted level in P2P trust model based on fuzzy comprehensive evaluation. The simulation results and analysis show that the membership function of trusted set can validate whether the trust evaluation value is sufficiently close to the trusted level.

Index Terms—Fuzzy comprehensive evaluation, trusted set, membership function, trusted level.
