Security in 5G Based Vehicular Communication Networks
Brought to you in a collaborative effort by IEEE Nebraska's Computer Technical Chapter and Communications Technical Chapter, Dr. Qian will discuss his research on 5G based vehicular communication networks.
Abstract
Vehicular networks are susceptible to various attacks from malicious nodes within a network. The collaborative misbehavior detection system can be used to detect these attacks. However, in a collaborative misbehavior detection system, an attacker may send false feedback which affects the detection accuracy. A trust model can be used to stimulate vehicles to send true feedbacks. However, an attacker can take advantage of weak or strong reputation update methods. A dynamic trust can be used to stimulate vehicles to send true feedbacks. In this talk, we present our latest research result on misbehavior detection in 5G based vehicular communication networks, by introducing a deep reinforcement learning based dynamic reputation update. In the proposed method, feedbacks from vehicles are combined in vehicular edge computing (VEC) servers using Dempster-Shafer theory and the results are used to predict the average number of true messages. VEC then uses deep reinforcement learning to determine the optimum reputation update policy to stimulate vehicles to send true feedbacks. In addition, through extensive simulations, we show that the proposed dynamic reputation policy is better in terms of the average number of true feedbacks compared to the existing reputation update policy.
