Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present disclosure, and are not used to limit the embodiments of the present disclosure.

[0028] First, before introducing the technical solutions of the embodiments of the present disclosure in detail, the technical background or technical evolution context on which the embodiments of the present disclosure are based is introduced. At present, in the scenario of autonomous vehicles in the vehicle formation, V2X communication is usually not encrypted, or only certified by V2X-CA. This communication method has the risk of remote control information being intercepted by a third party. Onc...

Abstract

The embodiment of the invention relates to a vehicle communication encryption method and device, a vehicle, a storage medium and a program product. The method comprises the steps of generating a first random number in a process that a target vehicle is merged into an original vehicle formation to establish a new vehicle formation, and receiving a second random number sent by a second vehicle in the new vehicle formation; generating a new formation communication key according to the first random number, the second random number and a preset key generation algorithm; and communicating with other vehicles in the new vehicle formation based on the generated new formation communication key. By adopting the method, the interactive information between the vehicles can be prevented from being tampered, and the safe driving of the vehicles is ensured.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of vehicle communication encryption, and in particular, to a vehicle communication encryption method, device, vehicle, storage medium, and program product. Background technique [0002] With the development of V2X communication technology and autonomous driving technology, more and more vehicles use V2X for vehicle-to-vehicle communication. One of the more widely used scenarios is vehicle autonomous driving formation. For example, the pilot vehicle is driven manually, and the follower vehicle receives the historical trajectory information and remote control information of the pilot vehicle through V2X for automatic driving. [0003] At present, in the scenario of vehicle autonomous driving formation, V2X communication is usually not encrypted, or only certified by V2X-CA. This communication method has the risk of remote control information being intercepted by a third party. Once int...
