Embodiment 1

[0057] This example assumes that the three vehicles are Vehicle 1 、Vehicle 2 and Vehicle 3 , the roadside unit is the RSU, and the law enforcement agency is the LEA. Take this as an example to specifically illustrate the above-mentioned links.

[0058] Link i (system initialization generates corresponding parameters):

[0059] The law enforcement agency LEA generates a bilinear map e: G×G→G T , where G is the additive cyclic group, G T is a multiplicative cyclic group of order q. Next, LEA selects the generator g in G, and in G r Choose two different generators g=e(g,g) and h=e(h,h) in . LEA sets the public parameter as para=(q, G, G T , g, g, h, e); Based on the above parameters, LEA selects x, y, x 1 , x 2 , x 3 , x 4 , x 5 , λ∈Z q ,calculate Then the LEA public key pk LEA =(λ, h, Y 1 , Y 2 , Y 3 , Y 4 , Y 5 ), private key sk LEA =(x 1 , x 2 , x 3 , x 4 , x 5 ).

[0060] Stage ii (the corresponding participant completes the registration):

Abstract

The invention discloses a batch authentication method for privacy protection in an Internet-of-Vehicles environment. The method comprises the following links of system initialization, registration of participants, message signature, message batch verification, real identity tracing of vehicles, regular updating of public keys of law enforcement offices and updating of vehicle certificates. The invention provides a privacy protection identity authentication protocol based on bilinear pairing, a vehicle signs a message related to traffic and sends the signature and a blind certificate to a nearby roadside unit, and the roadside unit can independently detect the validity of the message by using non-interactive zero-knowledge proof. According to the invention, a safe, efficient and privacy-protected identity authentication environment is provided for the Internet of Vehicles, and the privacy protection and traceability problems of vehicle identities are solved.

Description

technical field [0001] The invention belongs to in-vehicle communication technology, in particular to a batch authentication method for privacy protection in an Internet of Vehicles environment. Background technique [0002] The Internet of Vehicles is of great significance to the development of intelligent transportation systems. The Internet of Vehicles is a heterogeneous network that integrates communication between vehicles and other roadside facilities. This heterogeneous network enables vehicles to wirelessly exchange time-critical information such as road safety, navigation and other roadside services. In particular, roadside units (RSUs) have been equipped with edge computing devices to address computational complexity and transmission overhead issues. This enables the RSU to process vehicle authentication requests locally without relying on time-consuming cloud servers. [0003] However, the Internet of Vehicles architecture brings a large amount of real-time mes...
