Embodiment Construction

[0041] Embodiments of the present invention will be disclosed in the drawings below, and for the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary.

[0042] like Figure 1-4 As shown, the present invention provides a vehicle network authentication system, including four main bodies: an identity management trusted center TRA, a key generation center KGC, a roadside unit RSU and a vehicle user entity.

[0043] TRA (Trust Registration Authority): It is completely a trusted third-party center for VANETs. TRA is responsible for system initialization, roadside unit RSU and vehicle registration. The TRA is connected to the RSU through a secure channel. Only the TRA knows the real identity ID, and if necessary, the TRA will track the ID ...

Abstract

The invention relates to a fault-tolerant aggregation authentication method in an Internet of Vehicles scene. The method comprises a preparation stage, a user registration stage, a key generation stage, a signature stage, a pre-verification stage and a fault-tolerant aggregation verification stage. The key generation stage is divided into a KGC part key generation stage and a user key pair generation stage. The trusted third party TRA carries out identity management and identity registration on the vehicle and the roadside unit, generates a pseudonym identity list for the vehicle and updates the pseudonym identity list regularly; based on the characteristics of the high-density Internet of Vehicles, the efficiency is ensured by adopting batch authentication of vehicles; the filtering speed of illegal users is improved based on pre-verification of a neural network algorithm, and the fault-tolerant rate of aggregation signatures is improved by utilizing a fault-tolerant aggregation signature theory on the basis of common aggregation signatures.

Description

technical field [0001] The invention relates to a vehicle networking verification technology, a certificateless aggregation authentication technology, a neuro-fuzzy extraction algorithm, and a fault-tolerant aggregation method, in particular to a fault-tolerant aggregation authentication method in a vehicle networking scenario. Background technique [0002] VANET is an in-vehicle wireless network (eg, cars, buses, trucks) and adjacent roadside infrastructure. Each vehicle is equipped with a transmission that enables the vehicle to communicate with nearby vehicles and infrastructure. VANET consists of On Board Unit (OBU), Road Side Unit (RSU) and Trust Authority (TA). TA is a third-party device that is mainly responsible for RSU registration, vehicle certification, and monitoring of the entire network. The RSU is a fixed wireless device (eg WiFi, WiMAX) located at the roadside, acting as an intermediary between the traffic supervisor and the vehicle OBU, delivering safety i...
