[Abstract]:Vehicle networking (VANET) is a new mobile ad hoc network with practical needs and wide application prospects, which can effectively improve the driving experience and traffic safety. Vehicle networking has the characteristics of large scale of network and open wireless channel, which determines the necessity of guarding against internal and external security threats. Information security and privacy protection are the key issues in the research of vehicle networking. Vehicle networking must be strictly tested and verified before it can be put into commercial use. However, the field test of vehicle networking is very costly, so it is an effective way to verify the vehicle networking system by means of simulation platform. Based on the deep study of the security and privacy threats in vehicle networking, this paper analyzes the characteristics of distributed authentication architecture and the application of cloud computing technology in vehicle networking. The main work is focused on the research of the security and privacy protection mechanism of the cloud frame and alighting network, which aims to solve the problem by combining the security and privacy protection protocol and technology. The problems of information security and privacy protection encountered in the process of providing intelligent transportation services are discussed. On the other hand, on the basis of in-depth research on the working principle of iTTRIS, a related improvement and extension scheme is put forward and implemented in engineering. The main research work includes the following aspects: 1. This paper presents a security architecture model of vehicle networking based on multi-layer cloud. This model combines the research of vehicle network distributed authentication and cloud computing application in vehicle network, and it is divided into three levels: central cloud authentication center and local micro cloud authentication center, and OBU protection module. The analysis shows that the proposed model is more secure than the RSU-based distributed authentication model, and has good practical deployment capability and extensible capability. This paper presents a scheme of vehicle networking pseudonym management based on cloud security architecture. The scheme adopts the traceability protocol of tripartite participation and the certificate revocation mechanism based on counting Bloom filter, which can effectively reduce the malicious attack against certificate revocation. The performance analysis shows that the performance of this scheme is better than that of existing scheme. 3 in controlling CRL size and time complexity of undo operation. The improvement and extension of iTETRIS. Aiming at the inconvenient design of vehicle network simulation scene, the traffic model making software of simulation platform is designed and implemented, which improves the efficiency of simulation scene design and production, and aims at the demand of simulation platform expansion. The security module extension is designed and implemented, which solves the problem of the lack of key simulation entities and the inability to simulate the security scene of vehicle networking.
