摘要:

针对车联网中共谋节点可能协同发布虚假路况信息,导致路况信息共享过程中消息真实性无法保证的问题,提出了一种基于信誉积分的路况信息共享中共谋攻击节点检测方法。在路况信息聚合过程中,设计了恶意信息检测算法,能够检测到共谋节点发布的虚假消息,保证系统中传递消息的真实准确。安全性评估和实验表明,相比于现有方案,该方法对共谋节点的检测效率更高,共谋节点数量占比适应场景更广泛。

Abstract:

Aiming at the problem that on occasion of the release of false road condition information by collusion nodes in the Internet of vehicles collaboratively, message authenticity could not be guaranteed in the process of road condition information sharing, a method for detecting collusion attack nodes in road condition information sharing based on reputation points was proposed.In the process of road condition information aggregation, a malicious information detection algorithm was designed to detect false messages issued by colluding nodes, which could ensure the authenticity and accuracy of messages delivered in the system.Experimental results show that the proposed method has higher detection efficiency for collusion nodes and adaption to a proportion of collusion nodes through security evaluation and experiments in comparison with the existing schemes.

Key words: Internet of vehicles, road condition information sharing, blockchain, collusion attack
