This is a first step of a hybrid IDS method based on the analysis of spectral traffic and a robust controller / observer for the estimation of anomalies in UAV networks. This module is currently designed to observe the traffic between the drones and the Paparazzi GCS. It provides a statistic signature of the traffic which can later be used to determine the nature of the traffic. The module is tested in face of a DoS attack and the results are very promising!
