A consensus protocol design based on service proof and a vehicle networking application method thereof

Abstract

The invention discloses a consensus protocol design based on service proof and a vehicle networking application method thereof. In the consensus protocol, a vehicle can obtain an incentive (VPoSCoin)by providing service proof without relying on a third party messageable certification authority. VPoSCoin enables more nodes to actively cooperate with other vehicles by motivating vehicles to participate in V2V communication. In the scheme, a consensus protocol based on Proof of Services (Proof of Services) is designed. The whole block chain system is maintained by the roadside unit in the vehicle network, and the information is highly transparent.

Description

technical field [0001] The invention relates to the technical field of cyberspace security, in particular to a consensus protocol design based on service proof and a vehicle networking application method. Background technique [0002] According to data provided by the Ministry of Public Security of China, as of the end of 2017, the number of motor vehicles in China reached 310 million, including 217 million cars; the number of motor vehicle drivers reached 385 million, of which 342 million were car drivers. At the same time, the annual growth of motor vehicles exceeded 20 million units and continued to maintain a rapid growth trend. This is a considerable market in terms of both stock and increment. In the future, applications based on the automotive market will undoubtedly have broad prospects. [0003] In recent years, with the continuous development of intelligent manufacturing and related industries and technologies, the continuous development of IoV technology has been...

Problems solved by technology

However, the proliferation of vehicles has brought a heavy burden to this centralized vehicle networking architecture.

Secondly, vehicle-to-vehicle communication needs to consume resources such as the vehicle's battery, storage space, and communication bandwidth. Due to the lack of an effective incentive mechanism, many vehicles are unwilling to share communication resources and participate in the communication and message dissemination of Internet of Vehicles information.

In addition, there are some malicious behaviors in vehicle-to-vehicle communication, such as spreading false malicious messages, discarding messages, and even malicious attacks on the network, which will cause communication congestion and even lead to safety accidents in severe cases

Finally, the current design of most vehicle-to-vehicle communication incentive mechanisms does not fully consider user privacy, and many vehicle information such as in-vehicle voice or other related data are exchanged to requesters without the permission of the vehicle owner

[0005] In the traditional centralization-based incentive mechanism model of the Internet of Vehicles, although such systems work well in most cases, a single point of failure or malicious attack at any time may destroy the entire network, thereby directly endangering passengers and surrounding areas.
