基于信誉反馈的边缘设备信任评估算法
Edge Device Trust Evaluation Algorithm Based on Reputation Feedback
摘要
Abstract
To address the low accuracy of terminal device trust evaluation in the existing edge comput-ing environment and the inability to effectively deal with the security threats brought by malicious ter-minals to edge network services,an edge device trust evaluation algorithm based on reputation feed-back(EDTERF)is proposed.Firstly,the direct trust is determined based on the history of direct inter-action between devices,and a time attenuation factor is added to consider the timeliness of the trust.Secondly,during the interaction,fuzzy degree of nearness is used to analyze the reliability of device trust feedback and determine the recommended weight of device indirect trust.Finally,dynamic weights are used to fuse direct trust and indirect trust to obtain the global trust degree of the device.Ex-perimental results show that the EDTERF algorithm can effectively resist malicious node attacks and has high reliability.关键词
