摘　　要：通过分析复杂网络环境下网络实体的特性,建立基于自主信任决策的动态信任模型:定义信任的相关概念,提出了同构、非同构关系和基于这两种关系下直接信任、传递信任和自荐信任的计算方法,并在信任度值的计算中加入时间衰减因子、权重因子等动态因素,给出了信任决策和信任度值的更新算法,最后通过实验分析该信任模型的可行性和可信性.A dynamic trust model based on independent decisions is built in this paper by analyzing the characteristic of network entities in complex network environment.The paper defines the related concepts of trust,gives a new notion of the homogeneous relation and heterogeneous relation,and takes the direct trust,recommendation trust and self-recommendation trust into account.The time decay factor and weights factor are considered for computing the trust values.In addition,the update algorithm of trust value and the trust decision algorithm are provided in the model.Finally,the experiments are designed to demonstrate the feasibility and credibility of the trust model.
