Defense via Behavior Attestation against Attacks in Connected and Automated Vehicles based Federated Learning Systems

The recent application of Federated Learning algorithms in IOT and Wireless vehicular networks have given rise to newer cyber threats in the mobile environment which hitherto were not present in traditional fixed networks. These threats arise due to the intrinsic nature of wireless transmission medium and other inherent characteristics of mobile networks such as high-node mobility and rapidly changing topology. This paper investigates the robustness of Vehicular AttestedFL defense strategies against falsified information attacks by tracking the behavior. We show that the defense strategies are capable of detecting and eliminating malicious nodes in the wireless mobile setting of the future smart road networks.
