Game Theory Based Modelling of Unmanned aerial vehicles’ Onboard Software Integrity Attacks

Attacks on the integrity of Unmanned aerial vehicles (UAVs) onboard software are on the rise. Such attacks are very critical and can lead to man-made incidents. There are several approaches for modeling these attacks. This article explores the interaction between an attacker and a defender. The authors have developed a tree model for attacking firmware integrity. Using this attack-defense tree, a game-theoretic risk assessment scheme is formulated. The effectiveness of the proposed scheme was evaluated on the example of a firmware integrity attack and conclusions were shown confirming the viability of the proposed method.
