基于平衡权重的动态综合信任度量方法

Dynamic Global Trust Evaluation Based on Balance Weight

信任度量是面向开放式网络基于信任的访问控制可信管理中亟待解决的关键问题之一.根据人类社会学中信任的复杂关系,阐述了信任的相关概念,在基于信任的动态访问控制组成架构的基础上,考虑交互历史参数、奖惩因子、推荐实体评价可信度等多影响因子实现信任的计算,引入平衡权重因子解决直接信任和推荐信任的权重分配问题,提出了面向开放式网络基于平衡权重的动态信任综合度量方法.仿真结果与分析结果表明,该信任度量方法具有一定的鲁棒性和更好的动态自适应性.

The trust evaluation is one of the key issues that need to be resolved in credible trust management for trust-based access control in open networks. Referring to the complexity of trust relationships in human society, some relevant concepts on trust and proposes a dynamic comprehensive trust evaluation method for open networks was introduced. This method establishes a trust-based access control framework and introduces a balanced weight factor in trust evaluation to solve the problem for determining the weights between direct trust which includes historical information to improve accuracy and recommenda- tion trust which includes the bonus-penalty factor as well as the reliability of evaluation to improve reliability and efficiency. Experiment shows that the proposed method can achieve certain robustness and better dynamic self-adaptability.
