Embodiment Construction

[0078] It can be understood that in order to improve the security of in-vehicle information, for example but not limited to, the following two methods can be used for communication between in-vehicle devices:

[0079] 1. Before the in-vehicle equipment leaves the factory, the key will be filled in the production line by means of key filling, and then assembled into the vehicle. Subsequently, the in-vehicle equipment will communicate through the filled key to ensure the security of the in-vehicle information. However, the above-mentioned keys are managed by the key management system of the car factory. If the key store of the car factory leaks, the safety of all vehicles in the car factory will be greatly threatened. In addition, in order to improve in-vehicle security, it is necessary to periodically update the keys used by in-vehicle devices. However, every time the key is updated, it is necessary to go to the car factory to update the key for the equipment in the car, which...

Abstract

This application discloses a method and device for acquiring a key and a key management system and relates to the technical field of smart cars, which can not only improve communication security, but also can update the key at any time, which is very convenient. The key management system includes a key server, and a first node communicatively connected with the key server. The first node is a key client or key agent. The key server is used to obtain the first key information, and send the first key information to the first node. The first node is configured to receive the first key information from the key server, and generate the first key according to the first key information. The first key information includes the first key material and the identifidier of the first communication domain. The identifier of the first communication domain is used to indicate the first communication domain, The first key is applied to the first communication domain, The first communication domain includes at least two nodes in the key management system, The at least two nodes include the first node.
