Embodiment Construction

[0039] figure 1 Shows the vehicle-to-vehicle communication system (V2V). V2V communication systems can easily download updated certificate revocation lists (CRLs) from sources other than roadside equipment, which is usually the main communication interface device for updating CRLs. A V2V communication system includes a host vehicle that communicates with one or more remote entities. The remote entity can be a remote vehicle or an RSE. It should be understood that each vehicle considers itself a host vehicle with respect to vehicles that are remote from the host vehicle. Therefore, the term host vehicle refers in this context to the corresponding vehicle described in this specification.

[0040] A CRL is a list of digital certificates that have been revoked or are no longer valid. The host vehicle receives a message from a remote entity that the digital certificate for that message has been revoked or is no longer valid, the host vehicle should not rely on this message, and...

Abstract

A method is provided for obtaining a certificate revocation list (CRL) for a vehicle in a vehicle-to-vehicle communication system. A portable security unit is provided to access secured operations for the vehicle. The portable security unit is linked to a device having access to a communication network. The communication network is in communication with a certificate authority for issuing an updated CRL. The updated CRL is downloaded from the certificate authority to the portable security unit. At a later time, when a user enters the vehicle, a communication link is established between the portable security unit and a vehicle processor unit. Mutual authentication is exchanged between the portable security unit and the vehicle processing unit. The updated CRL stored in the portable security unit is downloaded to a memory of the vehicle communication system in response to a successful mutual authentication.

Description

technical field [0001] Embodiments generally relate to vehicle-to-vehicle communication systems. Background technique [0002] The use of certificate revocation lists (CRLs) to check certificate validity on the Internet has inspired the use of CRLs in other contexts, such as vehicle-to-vehicle communications. Since the vehicle is not within communication range of a roadside device that can provide reachability to the certificate authority, resulting in intermittent connectivity with the certificate authority, failure to renew a revoked certificate that is being verified will result in a Acceptance of revoked certificate message. In the vehicle communication system, the CRL is obtained through communication with roadside equipment. However, if the vehicle cannot communicate with the roadside equipment frequently, the vehicle will not be able to obtain an updated list of the CRL. Contents of the invention [0003] An advantage of an embodiment is that the updated certific...
