摘要

摘要: 该文首先从分析开放式网络环境中有关信任的问题和主观信任的模糊性入手，以模糊理论为基础，引入隶属度来描述信任的模糊性，解决了模糊信任模型的建模问题；以图论为基础，将网络环境模型化为一个无向图，定义了基于本地信息交互的信任评价规则；提出了基于开放式网络环境的模糊自主信任模型，具体研究了自主信任建立策略及建立完全可信网络的实现机制及条件；最后通过仿真实验讨论了网络拓扑结构对自主信任建立的影响，并以小世界网络模型(-model)为基础分析讨论了自主信任建立的速度问题，这为网络管理的研究提供了一个有价值的新思路。

Abstract: 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.
