为解决开放式网络环境中主观信任的模糊性和主体之间信任关系的动态性,提出了模糊自主信任模型。在该模型中,引入模糊理论的隶属度概念来描述信任的模糊性,解决了模糊信任的建模问题;以图论为基础,将网络环境模型化为一个无向图G(V,E),定义了基于本地信息交互的信任评价规则,建立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。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(-m ode l)为基础,分析了自主信任建立的速度问题。该研究也为开放式网络环境中信任管理的研究提供了一个有价值的新思路。
In order to solve the ambiguity of the subjective trust and the dynamic relationship between the parties in an open network environment, a fuzzy autonomous trust model is proposed. In this model, the concept of membership degree of fuzzy theory is introduced to describe the fuzziness of trust and solve the modeling problem of fuzzy trust. Based on graph theory, the network environment is modeled as an undirected graph G (V, E) , Defines the rules of trust evaluation based on local information interaction, establishes the mechanism and conditions for the establishment of an independent trust strategy and the establishment of a fully trusted network. Through the simulation experiments, the influence of network topology on the establishment of autonomous trust is discussed. Based on the small-world network model (-model), the speed of autonomous trust establishment is analyzed. The research also provides a valuable new idea for the research of trust management in open network environment.
