FIG. 1 is a flow diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The car owner withdraws the authorized key, but under the condition that the car and the client mobile phone are off-line and not networked, the authorized person can still use the authorized key to control the car until the authorized key is expired; the owner has cancelled the key that shares out, because the vehicle does not have the networking, can't accomplish and cancel immediately, so the key that loses efficacy in a certain time.
The invention provides a reliable failure method and a system of an offline digital key, wherein a cloud distributes shared keys in sections, the actual valid period of the keys reaching equipment is very short, when the keys at the equipment end reach a set expiration valve point, the cloud re-issues the keys, and a mobile phone prompts a user to re-pull the keys from the cloud, and the method comprises the following steps:
step S1: and the owner fills in friend information and clicks to share. Step S2: the cloud records the relationship between the vehicle and the friends and vehicles. Step S3: and logging in the app by the mobile phone of the friend. Step S4: the cloud generates a short-time key according to the relationship between friends and the vehicle; in this example, the time is one week. Step S5: the friend's cell-phone draws the key to the cell-phone, and the cell-phone keeps the key to the safe storage area. Step S6: when the user is about a week, the mobile phone of the friend logs in and automatically initiates the downloading of the key. Step S7: the cloud generates a week of keys again according to the time. Step S8: the friend's cell phone saves the key for the new week. Step S9: as above until the time limit for the owner to share with friends is reached.
The cloud controls key segmentation, the cloud keys are distributed safely, and the keys are updated safely by the terminal.
The cloud divides a longer key period into sections, so that keys can be rotated, a vehicle owner shares the keys with the keys of the service period of one year of friends, but the keys received by the actual mobile phone are generated according to the month, the period of one month is obtained every time, and only the keys of the next month are obtained every time through an updating mechanism.
Therefore, key protection points of the mobile phone are stored in a key generation mechanism at the cloud end, a key updating triggering mechanism at the mobile phone end and key use and safety of the terminal.
The invention also comprises a reliable failure system of the off-line digital key, which comprises the following modules: module M1: acquiring the service life of a vehicle shared by a vehicle master end to a user end; module M2: segmenting the service life of the vehicle to obtain a plurality of time limit segments, and respectively generating corresponding vehicle keys according to each time limit segment; module M3: and issuing the vehicle key corresponding to the time limit section to the user end according to the time when the user end logs in the cloud.
The cloud end segments the shared keys to obtain a plurality of time limit sections, the cloud end issues the key again after one time limit section is reached, and the intelligent end prompts a user to pull the key again to the cloud end. The cloud controls key segmentation, safe distribution of cloud keys and safe key updating of the terminal. The cloud divides the key period, the car owner shares the key with the user for a certain service period, the intelligent terminal receives the key generated by the division, and the user updates the key through an updating mechanism. The system comprises a key generation mechanism at the cloud end, a key updating triggering mechanism at the intelligent end, and key use and safe storage at the terminal.
The owner shares the digital key of the vehicle with friends, if the owner wants to withdraw, the owner needs to wait for the mobile phone to connect with the vehicle, and the mobile phone must be in a networking state, so that the withdrawal of the key can be completed. The key authorized by the vehicle owner to the friend is segmented, and the key in a new time period is required to be pulled by forcing the mobile phone of the friend to be networked for use in a certain time period, so that the key is withdrawn by the vehicle owner in such granularity, the key of the friend is withdrawn in a short time, and the problem that the mobile phone of the friend is not networked all the time and the friend can use the key all the time even if the vehicle owner withdraws the key is solved.
The invention mainly solves the key withdrawing and key failure functions under the condition that the equipment is not networked; the problem that the equipment is offline and cloud information cannot be synchronized to the terminal in time is solved, offline control can be achieved through the method, the method is a safety compensation measure for the equipment which cannot be networked in real time, the problem that the information cannot be synchronized to the terminal in time when a key is used offline is solved through the method, and the embarrassment problem that the equipment cannot be used for all times when a car is borrowed in an actual scene is solved; the key can be recovered in a short time, and the problem that the off-line key cannot be recovered after being used off-line for a long time is solved.
