摘要:

针对车联网(IoV)中合理地对车辆进行信任评估并及时更新多个路边单元(RSU)之间一致的信任值的问题,在已有的IoV信任管理方案基础上,提出一种基于区块链和多属性决策的IoV信任管理方案BCIoVTrust (BlockChain IoV Trust)。首先,通过属性值和动态属性权重计算车辆综合信任值和恶意概率标志值;其次,通过奖惩机制减少恶意车辆在IoV中停留的时间;最后,采用混合共识机制,以车辆信任值的绝对值之和作为权益,动态改变矿工节点的出块难度。实验结果表明,该方案能更全面准确地计算车辆信任值、识别和移除恶意车辆,并且更快地更新区块上存储的信任值,从而有效解决冷启动问题、动态调整信任衰减速率、合理选择最优推荐节点以及防止恶意车辆共谋串通。

Abstract:

Aiming at the problems of conducting reasonable trust evaluations for vehicles and ensuring timely updates of consistent trust values among multiple RoadSide Units (RSUs) in the Internet of Vehicles (IoV), a trust management scheme for IoV based on blockchain and multi-attribute decision making was proposed on the basis of the existing trust management schemes for IoV, named BCIoVTrust (BlockChain IoV Trust). Firstly, the comprehensive trust value and the malicious probability indicator of a vehicle were calculated by attribute values and dynamical attribute weights. Secondly, a reward and punishment mechanism was introduced to reduce the time that malicious vehicles stay in the IoV. Finally, a hybrid consensus mechanism was used to dynamically change the blocking out difficulty of the miner node by taking the sum of the absolute values of the vehicles' trust values as the stake. Experimental results show that the scheme can calculate the vehicle trust value more comprehensively and accurately, identify and remove malicious vehicles, and update the trust value stored on the blocks faster to effectively solve the cold-start problem, dynamically adjust the rate of trust decay, reasonably select the optimal recommended nodes, and prevent the malicious vehicles from conspiring and colluding.

Key words: Internet of Vehicles (IoV), multi-attribute decision making, blockchain, trust management, smart contract
