摘　　要：将区块链技术和车联网(internet of vehicles, IOV)技术相结合,提出一种基于惩罚机制的Gossip认证算法。采用窗口保护机制控制网络中节点的数量,避免因网络通道阻塞破坏共识信息的达成。利用Gossip协议保证信息高效传播,并提出惩罚机制降低共识过程中恶意节点的数量。算法分析和试验结果表明,该方法在保证通信安全的同时可以提高节点的共识效率,并有效弥补车联网中身份认证方面的缺陷。Combining blockchain technology and internet of vehicles technology, a Gossip authentication algorithm based on a penalty mechanism was proposed. This method adopted a window protection mechanism to control the number of nodes in the network and avoid the destruction of consensus information due to network channel blockage. The Gossip protocol was used to ensure the efficient dissemination of information, and a penalty mechanism was proposed to reduce the number of malicious nodes in the consensus process. Algorithm analysis and experimental results showed that this method could improve the consensus efficiency of nodes while ensuring communication security, and effectively compensated the defects of identity authentication in the internet of vehicles.
