a vehicle networking architecture based on block chain and a working method thereof

The invention discloses a vehicle networking structure based on a block chain and a working method thereof. The vehicle networking structure comprises an interconnected vehicle entity, a vehicle-mounted unit OBU, a roadside unit RSU, a core network and a block chain network. It has the typical characteristics of decentralization, distribution, collective maintenance and incapability of tampering.It can effectively solve the problem of centralization of traditional vehicle networking architecture and mutual distrust between entities. At that same time, the invention provides an undirected graph generation method, an identity privacy protection method and a location privacy protection method when the beacon information is uploaded by a vehicle, thereby solving the problem of identity and location privacy disclosure of a vehicle networking architecture based on a block chain. 本发明公开了种基于区块链的车联网架构及其工作方法，车联网架构包括相互连接的车辆实体、车辆车载单元OBU、路侧单元RSU、核心网：和区块链网络。具有典型的去中心化、分布式、集体维护、不可篡改的特点，能有效解决传统车联网架构的中心化、实体间相互不信任的问题。同时提供了车辆上传信标
