A method and system for transmitting and distributing Internet of Vehicles information against pollution attacks

Abstract

The invention discloses an anti-pollution attack car networking information transmission and distribution method and system. The method comprises the following three steps: messages initialization, messages verification and retransmission, and messages verification recovery. The system comprises the messages initialization module, the messages verification and retransmission module, and the messages verification recovery module. The system adopts the way of signature vectors to make up for the deficiencies of existing scheme. The scheme can defense pollution attacks, guarantee cars that receives messages and cars in motion filter any polluted data packages, and further restores the original messages when malicious cars forges or modifies any data packages in the network.

Description

technical field [0001] The invention belongs to the technical field of data security, and particularly relates to information transmission in the Internet of Vehicles. The dispatching center of the Internet of Vehicles is used as a source node, other moving vehicles are used as intermediate nodes, and the vehicle receiving information is used as a destination node. In combination, a method and system for the transmission and distribution of Internet of Vehicles information against pollution attacks are proposed. Background technique [0002] In the era of widespread Internet penetration, terminal devices such as computers, mobile phones, and cars are all part of the Internet. The Internet of Vehicles is a terminal that turns the car into the Internet. Through three steps: vehicle data collection, car network interconnection, and car network control dispatcher sending information, so as to realize the cooperation of customers, car manufacturers, third-party companies, transpo...

AI Technical Summary

Problems solved by technology

The homomorphic hash function scheme can enable the intermediate node to verify the correctness of the data before mixing the data packets with an algebraic method; based on the public key signature scheme, the generated signature needs to be verified and forwarded in the intermediate node multiple times, resulting in Larger data and lower transfer efficiency
