Intrusion detection method, device and equipment for Internet of Vehicles

Abstract

This application discloses an intrusion detection method and device for Internet of Vehicles. The method includes: judging whether the message received from the message sending vehicle terminal contains a token number, a time stamp, and a message text package; if the received message contains a token number, a time stamp, and a message text package, sending the token No. and time stamp are sent to the authentication center for authentication, wherein, the token number is requested by the authentication center when the message sending vehicle terminal needs to send a message, and the time stamp indicates the time when the token number is issued; in response to receiving the token number from The certification center's authentication pass message, open the message body package. The application solves the problem that a non-vehicle network registered user maliciously sends a message with a virus to an on-vehicle unit in the vehicle network and realizes an intrusion on the vehicle network.

Description

technical field [0001] The present disclosure generally relates to the field of computer technology, specifically to the field of network information security, and in particular to an intrusion detection method and device for the Internet of Vehicles. Background technique [0002] The Internet of Vehicles is a mobile autonomous vehicle formed by equipping vehicles with on-board units (OBU) that can communicate wirelessly, and laying network infrastructure (RSU) on both sides of the road to realize coordinated communication between vehicles and between vehicles and infrastructure. Organize the network to achieve the purpose of improving traffic safety, optimizing traffic efficiency, and facilitating traffic management. Vehicles in connected vehicles continuously configure themselves without the involvement of the network infrastructure. The on-board unit broadcasts beacon information such as road traffic and vehicle status to the network every 100-300 milliseconds, including...

AI Technical Summary

Problems solved by technology

After receiving the message, the vehicle-mounted unit opens the message, and the virus in the message quickly spreads in the vehicle-mounted unit, making the vehicle-mounted unit unable to work normally, that is, invading the vehicle-mounted unit

[0004] Therefore, the existing technology needs a method that can solve the problem that non-vehicle network registered users maliciously send virus-containing messages to vehicle-mounted units in the car network and realize the intrusion of the car network
