Secure event-triggered control for vehicle platooning against dual deception attacks

This paper addresses the challenge of achieving secure consensus in a vehicular platoon under dual deception attacks using an event-triggered control approach. The platoon consists of a leader and multiple follower vehicles that intermittently exchange position and velocity information to maintain stability. The study focuses on two types of deception attacks: gain modification attacks, where controller gains are manipulated, and false data injection attacks, which compromise sensor and control data integrity to destabilize the platoon. The research analyzes the duration, frequency, and impact of these attacks on system stability. To address these challenges, a robust event-triggered control scheme is proposed to ensure secure consensus despite the attacks. Sufficient consensus conditions are derived for both distributed static and dynamic event-triggered control schemes, considering constraints on attack duration and frequency. The influence of system matrices and triggering parameters on attack resilience is also analyzed. Additionally, a topology-switching scheme is introduced as a mitigation strategy when attack conditions exceed tolerable limits. The effectiveness of the proposed methodology is validated through simulations across various case studies, demonstrating its ability to maintain platoon stability under dual deception attacks.
