Internet of Vehicles communication control active security defense method and device

Abstract

The invention relates to an Internet of Vehicles communication control active security defense method and device. The method mainly comprises the following steps: a vehicle-mounted terminal presets adifferentiated key before distribution; before the vehicle management control terminal communicates with a vehicle, a random instruction is generated by using a dynamic algorithm, and the random instruction is returned to the vehicle-mounted terminal along with the control instruction; after receiving the control instruction, the vehicle-mounted terminal firstly calls the same dynamic algorithm togenerate a random instruction and matches the random instruction with the received random instruction, if the verification is passed, the instruction is executed, and if the verification fails, the execution of a postmark instruction is refused; and an instruction operation result is returned to the active section. According to the invention, communication control security of the vehicle management control terminal and the vehicle-mounted terminal can be realized in an intelligent Internet of Vehicles environment, the communication instruction is only valid in a certain time window, an attacker cannot simulate the instruction to control the vehicle, and the network attack of the Internet of Vehicles can be effectively resisted.

Description

technical field [0001] The invention relates to a safety defense method and device for the Internet of Vehicles, in particular to a communication control active safety defense method and device for the Internet of Vehicles, belonging to the field of information security. Background technique [0002] With the development of artificial intelligence and "Internet +", the Internet of Vehicles is gradually turning to intelligence, driverless technology is becoming more and more mature, and the architecture of cloud network terminal control has been formed. However, the Internet of Vehicles uses wireless communication, which has weak security capabilities and poses huge security risks. If network attacks cannot be effectively defended, the communication process between the vehicle and the control platform will be greatly threatened. In addition to causing data leakage, serious traffic accidents, casualties, economic losses, and even threats to social stability and national secu...
