Abstract

The invention discloses a vehicle and digital key pairing method and device, and the method comprises the steps: in response to a pairing request sent by a mobile terminal, determining a second feature parameter of a vehicle based on a physical unclonable component of the vehicle; determining a first key parameter and a calculation factor according to the pairing request sent by the mobile terminal; generating a vehicle session key according to the first key parameter, the second feature parameter and the calculation factor; and authenticating the mobile terminal based on the vehicle session key to obtain an authentication result, wherein the authentication result indicates whether the mobile terminal as a digital key is successfully paired with the vehicle or not. According to the scheme provided by the invention, the shared key can be generated based on the physical unclonable components of the vehicle and the mobile terminal and a key exchange algorithm without the intervention of a cloud server, so that the authentication of the vehicle and the mobile terminal is realized, the pairing security of the shared key is guaranteed, and the pairing process of the digital key and the vehicle is simplified.

Description

technical field [0001] The present application relates to the technical field of vehicle communication, in particular to a method and device for pairing a vehicle with a digital key. Background technique [0002] The keyless entry and keyless start system is the latest application and standard configuration of intelligent connected vehicles.
