在开放式网络环境中,主体间的信任存在错综复杂的关系。文章以复杂的网络环境为研究背景,同时为了保证信任评价的真实性,避免信任评价只局限于直接经验值,并提出了一种基于信任链的信任评价方法。该信任评价方法引入方差来检测主体间推荐信任评价的波动情况,将各信任链间方差值作为设置信任权重的重要因素,并参与信任值的计算。仿真实验表明,研究的信任评价方法对恶意信任评价能起到明显的约束作用,从而使得恶意节点提供的恶意信任评价的恶劣影响降低,为复杂的网络环境中的信任评价的研究提供了新的思路。

In the open network environment, there is a complex relationship between the trust of the subjects. In this paper, with a dense network environment as a research background, besides, in order to guarantee the authenticity of trust evaluation and avoid trust evaluation limiting to direct experience. This paper studies and proposes trust evaluation approach based on trust chain. The trust evaluation approach detects lfuctuations of recommendation trust evaluation between subjects with variance, and the variance between the trust chain is set up as an important factor in weight and participate in trust value computation. Simulation results show that, in this paper, the trust evaluation approach can play a signiifcant role in the constraints for malicious trust evaluation, So that reducing the adverse effects of trust evaluation from a malicious node, providing new valuable ideas on the study of trust evaluation for complex network environment.
