一种基于射线投影法的信任管理模型
Trust management model based on radial projection algorithm
摘要
Abstract
Aiming at the lack of universality and scalability in current trust management models, this paper proposed a trust management model based on the radial projection algorithm. This model defined the recommendation credibility degree and risk factor, and gave the formulas of transaction amount, correlation factor, attenuation factor and continuous reward factor. It used the public storage area to save nodes' computation and introduced storage space. The simulation and analysis results show this model not only improves the prediction accuracy of trust to meet universality and scalability, but also enhances the ability to distinguish between nodes of different acts, which can accurately identify malicious nodes, to ensure effectiveness and robustness.关键词
