[Abstract]:Vehicle networking realizes intelligent traffic management, decision making and control through real-time human vehicle-road-background interconnection perception. Its security authentication mechanism and trust model are the focus and difficulty of current research. In order to solve the main problem of vehicle network security, single authentication mechanism and trust model can not satisfy the security of vehicle network in complex multi-communication scenario. Full security of differentiation. This paper summarizes the research status and achievements of vehicle networking authentication mechanism and trust model for multi-communication scenarios. Outline, summarize the new direction, through in-depth study of the inherent mechanism of authentication mechanism, construct the authentication mechanism and theoretical framework according to the security requirements, and design the relevant protocols to achieve the security of different scenarios. Personalized authentication service of timeliness and privacy; A dynamic trust model based on the message and behavior of vehicle nodes is designed, which provides a strong real-time and accurate evaluation of trust, and provides a method support for actively perceiving malicious nodes. Considering that the future vehicle networking is likely to run in quantum communication environment, the research direction of quantum threshold anonymous authentication and quantum trust evolution decision-making mechanism is deduced. Finally, the safety evaluation and future development prospect of related research technologies are carried out.
