Figure 1 As shown, the method includes:

[0044] S110: Acquire vehicle data.

[0045] Among them, vehicle data may refer to vehicle-related data, such as audio and video data inside and outside the vehicle, vehicle location data, driver's operating data of driving the vehicle, etc.

[0046] Specifically, the audio and video data inside and outside the vehicle can be obtained in real time through sensors installed on the vehicle, such as cameras, ultrasonic radars, millimeter-wave radars, lidars, etc. The vehicle's location data, driver's vehicle operation data, etc. can also be collected through the vehicle network bus, such as the Controller Area Network (CAN), Ethernet, etc.

[0047] In this embodiment, the audio and video data inside and outside the vehicle can be acquired in real time through sensors installed on the vehicle, and the driver's vehicle operation data, location data, etc. can also be collected in real time through the vehicle CAN bus, etc.

[0048] S120: Determine grid information corresponding to the vehicle data based on a preset grid map.

[0049] Among them, the grid map can refer to a grid-based map representation method, which can be understood as dividing the map area into multiple small location areas, each of which is called a grid; each grid is provided with corresponding grid information, such as a grid name, etc. For example, the grid names corresponding to different grids can be set as administrative areas, key sensitive areas, etc.

[0050] Specifically, the grid map may be pre-set and stored in a vehicle electronic control unit (ECU), or the grid map may be pre-set and stored in a cloud.

[0051] In this embodiment, the grid corresponding to the vehicle data can be queried from the grid map preset in the vehicle ECU, and the grid name corresponding to the grid can be obtained; or the cloud can be connected to query the grid corresponding to the vehicle data from the grid map preset in the cloud, and the grid information corresponding to the grid can be obtained.

[0052] S130. Perform an encryption operation on the vehicle data based on the grid information to obtain encrypted vehicle data.

[0053] Specifically, different grids can use different keys. By presetting a one-to-one correspondence between grid information and keys of different grids, the encryption key corresponding to the grid can be determined according to the grid information of the grid. For example, the corresponding encryption key can be determined according to the grid name; the encryption operation is performed on the vehicle data corresponding to the grid according to the determined encryption key to obtain the encrypted vehicle data. For example, an encryption algorithm can be called to encrypt the vehicle data to obtain the encrypted vehicle data; or a cloud encryption interface can be called to encrypt the vehicle data to obtain the encrypted vehicle data.

[0054] In this embodiment, by acquiring vehicle data, the grid corresponding to the vehicle data is determined based on a preset grid map, and then the corresponding grid information is obtained; based on the grid information, the corresponding encryption key is determined, and the vehicle data is encrypted according to the determined encryption key to obtain the encrypted vehicle data; this solves the problem in the prior art that all data are encrypted using a set of keys, resulting in insecure encrypted data. The present invention determines the grid and grid information corresponding to the vehicle data through a preset grid map, which can facilitate the storage and regional classification of vehicle data; the corresponding encryption key is determined through the grid information to perform encryption operations on the vehicle data, and different grids use different encryption keys, so that rasterized encryption of the vehicle data can be achieved, effectively improving the security of the vehicle data.

[0055] Optionally, the vehicle data includes at least one of vehicle multimedia data, vehicle location data and driver vehicle operation data.

[0056] Among them, vehicle multimedia data can refer to the audio and video data inside and outside the vehicle; vehicle location data can be represented by the longitude and latitude data of the vehicle, which can be specifically understood as representing the vehicle location data by two coordinates of longitude and latitude. Driver vehicle operation data can refer to the speed and acceleration of the driver driving the vehicle.

[0057] In this embodiment, the audio and video data inside and outside the vehicle can be acquired in real time through sensors installed on the vehicle, such as cameras, radars, etc., and the vehicle's location data, driver's vehicle operation data, etc. can be acquired in real time through the vehicle network bus, such as CAN, Ethernet, etc.

[0059] Get the preset grid map;

[0060] Based on the vehicle position data, a grid corresponding to the vehicle position data is queried from a preset grid map to obtain corresponding grid information.

[0061] Specifically, a pre-set grid map can be obtained from the vehicle ECU or the cloud. According to the vehicle location data, i.e., the vehicle latitude and longitude coordinates, the pre-set grid map is used to query which grid area the vehicle is located in; and then the grid information corresponding to the grid, such as the grid name, is obtained.

[0062] In this embodiment, by acquiring vehicle data, based on the vehicle position data in the vehicle data, it is queried from the acquired pre-set grid map which grid the vehicle is located in, and then the grid information corresponding to the grid is obtained; by confirming the grid information of the acquired vehicle data, the storage and regional classification of the vehicle data can be facilitated.

[0063] Embodiment 2

[0064] Figure 2 This is a flowchart of a gridded vehicle data encryption method provided in the second embodiment of the present invention. The technical solution of this embodiment is further refined on the basis of the above embodiment. Figure 2 As shown, the method includes:

[0065] S210: Acquire vehicle data.

[0066] S220: Determine grid information corresponding to the vehicle data based on a preset grid map.

[0067] If the key is pre-set in the vehicle security encryption module (Trusted Execution Environment, TEE), execute S230-S250.

[0068] S230. Obtain a corresponding key slot ID based on the grid information.

[0069] The key slot ID may refer to a unique identifier of a stored key slot, and each key slot has a unique ID. Specifically, if the key is pre-set in the vehicle security encryption module TEE, the slot ID of the key corresponding to the grid information may be determined from the vehicle security encryption module TEE according to the one-to-one correspondence between the preset grid information and the key.

[0070] In this embodiment, the corresponding key slot ID can be obtained from the vehicle security encryption module TEE by presetting the correspondence between the grid information and the key.

[0073] S250, encrypting the vehicle data based on the encryption key to obtain encrypted vehicle data;

[0074] Specifically, the encryption algorithm is called to encrypt all vehicle data through the obtained encryption key to obtain the encrypted vehicle data. The encryption algorithm may adopt a symmetric encryption algorithm, such as AES algorithm, SM4, etc.

[0075] In this embodiment, by acquiring vehicle data, grid information corresponding to the vehicle data is determined based on a preset grid map. If the key is preset in the vehicle security encryption module TEE in advance, the corresponding key slot ID is obtained based on the grid information, and the corresponding encryption key is obtained based on the key slot ID; the vehicle data is encrypted based on the encryption key to obtain encrypted vehicle data; the encryption operation is performed by determining the corresponding encryption key through the grid information, and then the gridded encrypted vehicle data is obtained, which effectively improves the security of the vehicle data.

[0076] If the key is stored in the cloud in advance, execute S260-S280.

[0077] S260. Acquire corresponding interface information based on the grid information.

[0078] The interface information may refer to the name or identifier of the interface, etc. Specifically, if the key is stored in the cloud in advance, the interface information of the key corresponding to the grid information, ie, the grid name, may be queried from the cloud according to the preset one-to-one correspondence between the grid name and the key.

[0079] In this embodiment, the corresponding relationship between the grid information and the key can be preset to obtain the interface information of the key corresponding to the grid information from the cloud.

[0080] S270. Upload the vehicle data to the cloud based on the interface corresponding to the interface information, so that the cloud calls the corresponding encryption key according to the interface information to encrypt the vehicle data.

[0081] In this embodiment, all vehicle data can be uploaded to the cloud through the interface corresponding to the interface information. After receiving the vehicle information uploaded by the interface, the cloud calls the encryption key corresponding to the interface to encrypt the vehicle data.

[0082] S280. Receive the encrypted vehicle data returned from the cloud.

[0083] Specifically, after the cloud completes encryption of the vehicle data, the encrypted vehicle data is returned through the interface corresponding to the interface information.

[0084] In this embodiment, by acquiring vehicle data, grid information corresponding to the vehicle data is determined based on a pre-set grid map. If the key is stored in the cloud in advance, the corresponding interface information is acquired based on the grid information, and the vehicle data is uploaded to the cloud based on the interface corresponding to the interface information, so that the cloud calls the corresponding encryption key according to the interface information to encrypt the vehicle data, receives the encrypted vehicle data returned by the cloud, determines the corresponding encryption key through the grid information, performs encryption operation, and obtains gridded encrypted vehicle data, thereby effectively improving the security of the vehicle data.

[0085] Optionally, after performing an encryption operation on the vehicle data based on the grid information to obtain the encrypted vehicle data, the method further includes: securely storing the encrypted vehicle data.

[0086] Specifically, the encrypted vehicle data can be securely stored in a storage module inside the vehicle, or sent to a server outside the vehicle or a cloud storage service for secure storage.

[0087] In this embodiment, after obtaining the encrypted vehicle data, the encrypted vehicle data can be securely stored in a storage module inside the vehicle to ensure the privacy and security of the vehicle data; or sent to an external server or cloud storage service of the vehicle for secure storage, which can effectively prevent the data from being tampered with or lost, and facilitate remote access and management of vehicle data by vehicle owners or relevant organizations.

[0088] For example, Figure 3 A timing diagram of a rasterized vehicle data encryption method provided in the second embodiment of the present invention, such as Figure 3 As shown, the process of acquiring vehicle data, determining grid information corresponding to the vehicle data, and performing encryption operation on the vehicle data based on the grid information to obtain encrypted vehicle data may be:
