Abstract

The invention provides a reliable failure method for an off-line digital key. The method comprises the following steps: S1, acquiring the service life of a vehicle shared by a vehicle owner to a user side; S2, segmenting the service life of the vehicle to obtain a plurality of time periods, and generating a corresponding vehicle key according to each time period; S3, according to the time when the user side logs in the cloud, issuing the vehicle key of the corresponding period to the user side. The problem that the cloud information cannot be synchronized to the terminal in time when the equipment is offline is solved, offline control is achieved, the method is a safety compensation measure that the equipment cannot be networked in real time, and the embarrassing problem that the information and the terminal cannot be synchronized in time when a key is used offline and the vehicle cannot be used all the time in an actual scene is solved.

Description

technical field [0001] The present invention relates to the technical field of equipment digital keys, in particular to a method and system for reliably invalidating offline digital keys. Background technique [0002] Mobile smart terminal equipment and related technologies have developed rapidly in recent years, carrying more and more functions related to basic necessities of life. At this time, mobile smart terminal products are not only used as communication tools, but also as bank cards, traffic cards, and smart home control. Functions such as terminals are used. The function of a mobile smart terminal device as a car key is one of the hot technologies that have emerged in recent years, and this function is also called a digital car key. Different from traditional car keys, digital car keys do not require additional physical car keys, but integrate car key functions into mobile smart terminal devices. Based on security technologies such as SE and TEE, digital car keys u...
