There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The objective of the proposed research is to secure Additive Manufacturing (AM) systems from the perspective of side-channels. On the one hand, we propose a practical Intrusion Detection System (IDS) leveraging side-channel signals in AM systems. On the other hand, we explore technical methods to fight against side-channel attacks to steal Intellectual Property (IP) in AM systems. For the IDS, we propose a novel framework called NSYNC to compare two side-channel signals in real-time. As of now, NSYNC is the only IDS that can efficiently compare two side-channel signals with time noise, which is the random variation of the duration of G-code instructions. To protection IP in AM systems, we propose a novel method called movement obfuscation to inject fake movements in a printing process to confuse an attacker. In addition, we propose an optimization-based method to find optimal patterns to be injected into the side-channels to obstruct side-channel attacks.
