A method, apparatus and device for storing vehicular data. An embodiment of a method for storing vehicular data includes: analyzing importance of received vehicular data to determine a storage level of the vehicular data; acquiring a corresponding key and a corresponding encryption algorithm based on the storage level of the vehicular data; encrypting the vehicular data using the acquired key and the acquired encryption algorithm; and storing encrypted vehicular data in a storage area corresponding to the storage level of the vehicular data. The embodiment may improve the safety of vehicular data by encrypted storage of the data in different levels, effectively prevent important vehicular data from being illegally read or maliciously falsified, and improve the storage efficiency of the vehicular data.

Method, apparatus and device for storing vehicular data

A method and apparatus for acquiring vehicular data. An embodiment of the method includes: acquiring vehicular data of an autonomous vehicle equipped with a vehicular data acquisition device by the vehicular data acquisition device, the vehicular data comprising: a control instruction of the autonomous vehicle and sensor data from a sensor on the autonomous vehicle; encrypting the vehicular data to obtain encrypted vehicular data, and storing the encrypted vehicular data; receiving a request for acquiring vehicular data sent by a server; and sending the encrypted vehicular data to the server when the vehicle identifier is identical to a vehicle identifier of the autonomous vehicle and the device identifier is identical to a device identifier of the vehicular data acquisition device.

Method and apparatus for acquiring vehicular data

The objective of the present disclosure is to provide a method and device for communicating securely between a T-Box device and an ECU device in an Internet of Vehicles system. Specifically, sending, by a T-Box device, a first piece of information to a corresponding ECU device; generating, by the ECU device, a second piece of information; generating, by the T-Box device, a third piece of information; generating, by the T-Box device, a first key; encrypting, by the T-Box device, a to-be-issued instruction based on the first key; generating, by the ECU device, a second key; and decrypting, by the ECU device, the encrypted instruction based on the second key to obtain the instruction. Compared with the prior art, the present disclosure achieves the secure communication between the T-Box device and the ECU device.
