Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific examples of implementation.

[0025] figure 1 It is a flow chart of the method of the present invention, comprising the following steps:

[0026] (1) Vehicle identity authentication system entity initialization

[0027] (1.1) Authentication Authority (TA) initialization

[0028] TA configures the parameters required for the signature in the vehicle identity authentication system, and the system parameters are (q, U, U’, G, G’, G T ,e,p,p',Enc(),event,h); where TA randomly selects is the private key, and calculate U=up∈G and U′=up′∈G′; G and G′ are two additive cyclic groups, G T is a multiplicative cyclic group; p and p' are the generators of G and G' respectively, and ψ(p')=p, that is, G and G' are isomorphic; e is an effective bilinear pairing mapping: e:G ×G′→G T ;Enc() is a secure symmetric encryption algorithm; event is a system event; h is a hash...

Abstract

The invention relates to a certificate-based vehicle identification method for use in an internet of vehicles. The method is characterized in that a vehicle is independently identified with a time-limited certificate which is issued by a region server and replacing the true identity of the vehicle; the vehicle detects a malicious vehicle identity and transmits it to the region server; after receiving the malicious vehicle identity and its signature, the region server traces region registration information of the true identity and transmits the region registration information to a certification center; the certification center confirms the true identity of the vehicle and revokes the identity. The method has the advantages that the problem that the failure of the vehicle to independently finish the identification process by the existing Sybil attack detection method causes attack detection delay is solved; extra space and computation overhead caused by revoking of the vehicle identity are avoided; independent vehicle identification and privacy protection are achieved; the true identity of each malicious vehicle can be traced so that re-attacks of the malicious vehicles are prevented.

Description

technical field [0001] The invention belongs to the field of vehicle identity authentication in the Internet of Vehicles, and in particular relates to a certificate-based vehicle identity authentication method. Background technique [0002] Vehicle identity authentication technology is the basis of Internet of Vehicles services. Without identity authentication technology, vehicles cannot judge the authenticity and validity of received messages, and under the influence of Sybil attacks launched by malicious vehicles, vehicles will make wrong judgments and cause serious damage. traffic accident. [0003] At present, in the existing Sybil attack detection technology, the vehicle needs the help of the roadside infrastructure (RSU) to complete the vehicle identity authentication. These technologies are used in an Internet of Vehicles environment where RSUs are sparsely arranged. Malicious vehicles launch Sybil attacks in an environment where there are no RSUs nearby. The attacke...
