Digital key authorization issuing and withdrawing method and system

Abstract

The invention provides a digital key authorization issuing and withdrawing method and system, and the method comprises the following steps: S1, a key management platform carries out the operation of adding or deleting a key, a white list is locally updated after the operation succeeds, and the data in the white list is a set of key serial numbers; S2, other equipment synchronizes the updated white list to the vehicle end; S3, the vehicle end checks the validity of the white list and stores the white list, whether the serial number corresponding to the key is in the white list or not is checked through security authentication, and if the serial number does not exist in the white list, it is judged that the key is illegal. According to the method and system, a data list capable of identifying corresponding key information is maintained, and the list of the data corresponding to the key information effectively supports key revocation operation; issuing and withdrawing operations of the digital key are effectively supported; and on the premise that the number of available keys is always limited, the reliability of the operation of recording the key state is kept by the vehicle end.

Description

technical field [0001] The present invention relates to the technical field of car keys, in particular to a method and system for issuing and retrieving authorized digital keys. Background technique [0002] The car key has roughly experienced several developments of mechanical key-chip key-remote key-keyless start-digital key. Every upgrade of the car key keeps pace with the upgrade of the overall technology of the car. [0003] The intelligence, portability and security of the digital key are incomparable to the traditional key. Users don’t have to worry about the problem of losing or forgetting to carry the key. The usage scenarios are also more diversified, such as key sharing and revocation, and personalized customization for users. Wait for the scene. [0004] At present, the most widely used solution for the overall architecture of digital keys is the cloud-device-car tripartite interconnection. The key management mainly relies on the cloud, and the device is transfe...

Problems solved by technology

[0007] The key status depends on the device networking to actively obtain the cloud key data and status. When the device or vehicle is not connected to the network, the latest key status cannot be obtained from the cloud in time. At this time, there will be a risk. When the key expires or reports the loss and other scenarios , after the revocation operation is performed on the key of the owner or the shared person in the cloud, it cannot be synchronized to the device in time. At this time, the key information on the offline device is still valid. When the key status is recorded by the device, the vehicle and the offline device can still be authenticated , not safe for vehicles
