Abstract

The invention provides a secure information transmission method based on a vehicle-mounted network and a block chain. A transmitting module, a receiving module and an authentication module are included. A public key encryption mechanism is used to carry out signature and identification on all instructions sent by the modules, encrypted time stamps of multiple modules are added to a message, area blocks are packaged, and a block chain is formed. The access difficulty of an attack module is increased, a pseudo instruction of the attack module is blocked effectively, decentralization is carried out, a central bottleneck is reduced, all records formed during a vehicle driving process are recorded on the block chain, and first-hand information is provided for a vehicle monitoring platform and vehicle model validation for a vehicle digital twin.

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...
