Unmanned equipment key management system, method, device and equipment and storage medium

Abstract

The invention discloses an unmanned device key management system, method, device and equipment and a storage medium, a key management server obtains a request based on a key version carrying a token sent by an unmanned device, and sends a current version of a key to the unmanned device under the condition of judging that the token carried in the request has an obtaining permission; and when the unmanned device determines to update the key according to the current version of the key, the unmanned device requests to acquire the key of the current version from the key management server, and stores the key of the current version in the own security environment. It can be seen that in the unmanned device key management system and method provided by the present specification, the unmanned device stores the key sent by the key management server in its own secure environment, and even if the unmanned device is located in an area where communication signals are poor, the key stored in its own secure environment can be used, thereby improving the security of the unmanned device. The problem of availability of the secret key when the unmanned device is in signal disconnection is solved.

Description

technical field [0001] This specification relates to the field of unmanned driving technology, and in particular to a key management system, method, device, device and storage medium for unmanned equipment. Background technique [0002] Unmanned equipment can realize autonomous driving in the environment and reach the destination by sensing the surrounding environment. Among them, in order to ensure the security of communication between the unmanned device and the server, and between other unmanned devices, as well as the security of the data stored by the unmanned device itself, the unmanned device needs to use a key to encrypt the communication between each unmanned device, the unmanned device Internal communication and sealing sensitive data in unmanned equipment. Therefore, the management of keys for unmanned devices is particularly important, and it is necessary to establish a key management system that can manage keys for each unmanned device. [0003] In the prior a...

Problems solved by technology

[0004] However, because in the centralized key management system, the unmanned device does not store the key, and only requests the key management center to obtain the key when it needs to use the key, which leads to the centralized key management system relying on The wireless communication link between the unmanned device and the key management center realizes the request and transmission of the key. If the unmanned device is located in an area with poor communication signal, the unmanned device cannot request the key or the key management center cannot The situation of sending the key makes it impossible for the unmanned device to obtain the key in real time, thus making it impossible to encrypt communication and seal the data in the unmanned device
