Authorization system and method for vehicle remote diagnosis

Abstract

The invention discloses an authorization system and method for vehicle remote diagnosis. The system comprises a diagnosis equipment module, a diagnosed vehicle module and a bill server module, wherein the diagnosis equipment module, the diagnosed vehicle module and the bill server module are correlated with one another and included in a state storage assembly, and through a state table in the storage assembly, remote authorized diagnosis for a diagnosed vehicle is displayed. The method includes the steps that an authorization bill is requested for, bill and diagnosis strategy generation is performed, the bill is issued and received, and authorization is completed. The bill server is introduced for performing validity verification on the identities of participants of a diagnosis conversation and performing authorization, and under a non-symmetric cipher mechanism, a system frame based on the bill server is used for achieving mutual authentication for the identities of the diagnosis bodies, freshness, privacy, completeness and non-repudiation of the authorized bill and a management mechanism for a diagnosis instruction, improving security of the vehicle remote diagnosis conversation and guaranteeing that the bill is effectively issued in time.

Description

technical field [0001] The invention relates to the technical field of vehicle remote diagnosis, in particular to a vehicle remote diagnosis authorization system and method. Background technique [0002] As a part of ensuring traffic safety in intelligent transportation, vehicle remote fault diagnosis is the future development direction of automobile diagnosis technology. Traditional vehicle diagnosis refers to determining the technical condition of the vehicle and identifying the fault location and cause of the fault through the diagnostic instrument deployed on the vehicle maintenance side without dismantling the vehicle (or only removing individual parts). These diagnoses include detection and diagnosis of vehicle hardware, such as vehicle engine, detection and diagnosis of vehicle chassis, and configuration parameter correction or version update of vehicle software. [0003] Remote vehicle diagnosis means that the diagnostic equipment obtains the fault information of th...

Problems solved by technology

At the same time, the diagnostic equipment will also fail to diagnose due to the inability to verify the identity of the vehicle

On the other hand, when the ticket server suffers a denial of service attack, the diagnostic equipment will not be able to diagnose the faults of the vehicle in a timely manner, thus causing safety hazards to the driving vehicle and the owner
