Research of Fuzzy Autonomous Trust Establishment Strategy
模糊自主信任建立策略的研究

Firstly, this paper analyzes some questions of trust and the fuzziness of subjective trust, based on fuzzy set theory, the fuzziness of trust is described by membership function, and how to create the fuzzy trust model has been solved. Secondly, based on the graph theory, the network is modeled as an undirected graph , and the rule of trust evaluation is defined by the aid of local information interaction. Thirdly, the model of fuzzy autonomous trust establishment based on open network environment is proposed; trust establishment strategy, the mechanism and condition of establishing a fully trusted network are studied in this paper. Finally, the influence of network topology to autonomous trust establishment is discussed through simulation experiment, and the convergence rate of autonomous trust establishment based on the small-world model ( -model) is analyzed in this paper, which enlightens a new way for network management.
