Intrusion detection method and device and equipment for internet of vehicles

Abstract

The application discloses an intrusion detection method and device and equipment for Internet of Vehicles. The method comprises the following steps: judging whether a message received from a message sending vehicle terminal contains a token number, the timestamp, and a message text packet; sending the token number and the timestamp to a certificate authority to be certificated if the received message contain the token number, the timestamp and the message text packet, wherein the token number is granted by requesting to the certificate authority through the message sending vehicle terminal when needing to send the message, and the timestamp represents the time of granting the token number; and opening the message text packet in response to the received certificate passing message from the certificate authority. The problem that an unregistered user of the Internet of Vehicles maliciously sends the message with the virus to a vehicle-mounted unit and others in the Internet of Vehicles to realize the intrusion to the Internet of Vehicles is solved by use of the method and device disclosed by the application.

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
