  Unmanned aerial vehicles (UAVs) have gained much attention in recent years
for both commercial and military applications. The progress in this field has
gained much popularity and the research has encompassed various fields of
scientific domain. Cyber securing a UAV communication has been one of the
active research field since the attack on Predator UAV video stream hijacking
in 2009. Since UAVs rely heavily on on-board autopilot to function, it is
important to develop an autopilot system that is robust to possible cyber
attacks. In this work, we present a biometric system to encrypt the UAV
communication by generating a key which is derived from Beta component of the
EEG signal of a user. We have developed a safety mechanism that would be
activated in case the communication of the UAV from the ground control station
gets attacked. This system has been validated on a commercial UAV under
malicious attack conditions during which we implement a procedure where the UAV
return safely to a "home" position.
