Fast encryption and decryption-oriented car networking key management method based on reinforcement learning

Abstract

A fast encryption and decryption-oriented car networking key management method based on reinforcement learning, involving car networking communication and security. Aiming at the personalized communication needs of Internet of Vehicles users and preventing data leakage, a key management method for Internet of Vehicles oriented to fast encryption and decryption based on reinforcement learning is designed. Based on information such as interference power received by vehicles in the Internet of Vehicles, key duration, and vehicle density, the method uses reinforcement learning to continuously optimize the vehicle key update frequency and key length to prevent data leakage. The proposed method can adapt to the dynamic Internet of Vehicles environment and prevent eavesdropping attacks, improve the anti-eavesdropping interception rate of vehicle communication, and reduce the delay of secure communication.

Description

technical field [0001] The present invention relates to a method in the field of vehicle networking communication and security technologies, in particular to a reinforcement learning-based fast encryption and decryption-oriented vehicle networking key management method. Background technique [0002] As an important self-organizing network for information exchange, the Internet of Vehicles provides vehicle users with information such as location, road safety, and weather, and improves the driving experience and safety level of vehicle users. However, due to the openness and high dynamics of the Internet of Vehicles, vehicle users face security threats such as eavesdropping, interference, and information tampering, which brings major challenges to the large-scale deployment of the Internet of Vehicles. The Internet of Vehicles usually uses encryption technology to encrypt the communication content, which ensures the security of the communication content and improves the securi...
