Abstract

The present invention provides a security information transmission method based on the vehicle network and block chain, including a sending module, a receiving module, and an authentication module, which uses a public key encryption mechanism to sign and authenticate all instructions sent by the module, and then after the message Add the encrypted time stamps of multiple modules, encapsulate them into regional blocks, and form a blockchain. Increase the access difficulty of the attack module, effectively prevent the pseudo-instruction of the attack module, decentralize and reduce the central bottleneck, and record all records formed during the driving process of the vehicle on the blockchain. For the vehicle monitoring platform and vehicle digital Twin's car model verification provides first-hand information.

Description

technical field [0001] The invention belongs to the field of in-vehicle network communication, relates to a method for transmitting safety information, in particular to a method for transmitting safety information based on in-vehicle network and block chain. Background technique [0002] The in-vehicle network currently used in automobiles is based on a combination of several different data network protocols, the first of which is the Controller Area Network (CAN), which is mainly responsible for the powertrain and other related functions; the second is the Local Interconnect Network (LIN) , mainly for passenger and driver comfort uses that are not time-sensitive (such as climate control, ambient lighting, seat adjustment, etc.); the third is Media Oriented System Transport (MOST), developed for infotainment systems; Four are FlexRay for anti-lock braking (ABS), electronic power steering (EPS) and vehicle stability functions. [0003] For automobiles, the weight of wiring i...
