A method for safe storage and sharing of Internet of Vehicles data based on hybrid architecture

Abstract

The invention relates to the technical field of vehicle networking safety communication, and discloses a method for safely storing and sharing vehicle networking data based on a hybrid architecture. The specific steps are as follows: S1 when there is a vehicle V i When you want to join the Internet of Vehicles, you need to obtain the corresponding public and private key pairs from TC and PKG respectively, and use this as the account number and login password similar to the traditional network. The invention uses the double-chain structure of the alliance chain-private chain to solve the problem of data integrity and security in the communication process, introduces the central authority for generating the private key in the identity-based digital signcryption algorithm, and designs a The ring signature scheme involving the binomial distribution of discrete centers combines edge computing technology with cloud computing technology to achieve the real-time and efficient purpose of the vehicle network. The reputation evaluation algorithm and node classification are introduced into the practical Byzantine fault tolerance mechanism (PBFT), which improves the High latency in the communication process.

Description

technical field [0001] The invention belongs to the security communication field of the Internet of Vehicles, and relates to the block chain technology, the identity-based digital signcryption algorithm, the edge computing technology and the cloud computing technology in the field of information security. Background technique [0002] According to the statistics of the Ministry of Public Security, there will be 33.28 million newly registered motor vehicles nationwide in 2020, an increase of 1.14 million or 3.56% over 2019. According to data analysis, there are nearly 200,000 traffic accidents in China every year, and an average of 1 person is killed in traffic accidents every 8 minutes. Vehicles in the IoV environment are equipped with advanced on-board sensors and intelligent electronic equipment, and are further equipped with a wireless communication device on-board unit (OBU), which can effectively complete the interactive communication between members of the IoV.

Problems solved by technology

In addition, if the vehicle's identity information is leaked during the communication process, private information such as the vehicle's location and running track may be exposed

Because the safety and integrity of traffic information is almost related to the protection of people in the car, once the transmitted data is wrong, it may cause traffic accidents and casualties
