Efficient anonymous identity authentication method in Internet of Vehicles environment

Abstract

The invention provides an efficient anonymous identity authentication method in an Internet of Vehicles environment, and belongs to the technical field of Internet of Vehicles security. According to the technical scheme, the method comprises the following steps of vehicle offline registration, online registration and rapid identity authentication. The method has the beneficial effects that a temporary identity certificate Token mechanism is set, so that the authentication efficiency is improved while the vehicle anonymous two-way communication is realized; a block chain distributed account book mode is utilized, so that data traceability and tamper resistance are guaranteed, and the problems of relatively low identity authentication efficiency, easiness in attack and the like caused by traditional PKI authentication centralization of the Internet of Vehicles are solved; the combination of the blockchain PBFT consensus mechanism and the smart contract greatly reduces the authenticationtime delay of the traditional method.

Description

Technical field [0001] The invention relates to the technical field of car networking security, in particular to an efficient anonymous identity authentication method in a car networking environment. Background technique [0002] Internet of vehicles (IOV) is an open heterogeneous network composed of Vehicular Ad-HocNetwork (VANET) and mobile Internet. It realizes intelligent transportation through the real-time association and perception of vehicles, roads, and management platforms. Provide traffic safety, infotainment and other services. [0003] The basic structure of the Internet of Vehicles is mainly composed of three main parts: the traffic management center (TRC), the roadside unit (RSU), and the on-board unit (OBU): [0004] (1) The Traffic Management Center (TRC) is the highest authority in VANET. It is connected to the roadside unit (RSU) through a wired connection. It is mainly responsible for the initialization of traffic participants and the storage of core information;...

Problems solved by technology

[0009] (2) Security of authentication nodes: Most of the authentication nodes RSU in the Internet of Vehicles are independent, unmanned operation and management

Cui Yongquan et al. proposed "Grid-based Ring Signature Privacy Protection for Internet of Vehicles", and designed a ring signature scheme using the lattice difficulty problem to achieve unconditional anonymity and ensure its security under quantum attacks, but the length of the lattice signature needs to be optimized.

[0018] (3) Anonymous authentication based on distributed public key infrastructure: Chen Jianguo et al. proposed the "Security and Privacy Protection Scheme for Internet of Vehicles Based on Tickets", which uses tickets to provide anonymous access and authentication for application services. However, with the increase in the number of vehicles, tickets Processing latency becomes an issue

Solve the authentication between cars and multi-servers and roadside units, but due to the large number of vehicles and frequent communication, there is a lack of efficient and fast consensus mechanism

[0020] It can be seen that none of the existing technologies can achieve efficient anonymous authentication in the Internet of Vehicles environment.
