Defending Side Channel Attacks in Cyber-Physical Additive Layer Manufacturing Systems

Additive layer manufacturing has been termed as one of the proponents of the fourth industrial revolution. However, due to the presence of cyber and physical domain components in additive manufacturing, they are prone to physical-to-cyber domain attacks. One of the example of such attacks is side-channel attacks, where an attacker can steal valuable intellectual property of the 3D objects being printed by the additive manufacturing system. To understand and defend these attacks, we have to analyze all the possible side-channels and minimize the amount of leakage in each of them.
