Embodiment Construction

[0061] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings, but it is not intended to limit the present invention.

[0062] The model diagram of the vehicle safety communication system based on block chain in the present invention, such as figure 1 As shown, the system mainly includes the LEA responsible for managing the system vehicle information, authorizing the CA to issue certificates to the vehicle, and updating the key. CA assists LEA to issue certificates to vehicles, is responsible for updating system keys, and is also the verification node of the system. The RSU roadside unit, the verification node of the system, interacts with the vehicle during the vehicle data exchange process to ensure the accuracy of the information.

[0063] The vehicle safety communication method based on the block chain of the present invention, the first step is to initialize the vehicle networking system and establish ...

Abstract

The invention discloses a vehicle safety communication method based on a block chain, which comprises the following steps: (1) initializing an Internet of Vehicles system, establishing parameters required by the system, sending information for proving the identity of a vehicle to an LEA when the vehicle enters, and verifying the identity of the vehicle by a verification node in the system; (2) enabling the LEA to issue a certificate to the verified vehicle, record the identity information of the vehicle, and finally upload the identity information to a block chain, wherein the vehicle communicates with the vehicle, the vehicle communicates with a roadside unit RSU, and a polygonal network multicast mode is adopted as the communication mode; and (3) updating the parameters: updating the parameters in the system when the validity of the parameters expires or the parameters may be attacked and the confidentiality is threatened. According to the invention, the problems of communication safety and privacy protection of vehicles in the Internet of Vehicles can be effectively solved. Compared with the traditional Internet of Vehicles, the blockchain technology is used to replace a trustedthird party, the problem of single node failure is solved, and safe exchange of data between vehicles is realized.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for vehicle safety communication based on block chains. Background technique [0002] With the rapid development of wireless networks, intelligent transportation has also made great progress, and the Internet of Vehicles has begun to receive widespread attention. In the Internet of Vehicles, vehicles can improve vehicle driving efficiency and protect people's lives and property by sharing information such as traffic and road conditions. Security and privacy protection are the primary issues that the Internet of Vehicles must solve. The traditional Internet of Vehicles is based on centralization and relies on a trusted third party. However, there is a problem of single node failure in the centralized system. At present, except through legal means, existing technologies cannot ensure the security of data stored in third-party databases. Blockchain is a distributed l...
