Abstract

Recent inexpensive nanosatellite designs employ maneuvering thrusters, much as large satellites have done for decades. However, because a maneuvering nanosatellite can threaten HVAs on-orbit, it must provide a level of security typically reserved for HVAs. Securing nanosatellites with maneuvering capability is challenging due to extreme cost, size, and power constraints. While still in the design process, our low-cost SecureCPS architecture promises to dramatically improve security, to include preempting unknown binaries and detecting abnormal behavior. SecureCPS also applies to a broad class of cyber-physical systems (CPS), such as aircraft, cars, and trains. This paper focuses on Embry-Riddle’s ARAPAIMA nanosatellite architecture, where we assume any off-the-shelf component could be compromised by a supply chain attack.¹ Based on these assumptions, we have used Vanderbilt’s Cyber Physical - Attack Description Language (CP-ADL) to represent realistic attacks, analyze how these attacks propagate in the ARAPAIMA architecture, and how to defeat them using the combination of a low-cost Root of Trust (RoT) Module, Global InfoTek’s Advanced Malware Analysis System (GAMAS), and Anomaly Detection by Machine Learning (ADML).² Our most recent efforts focus on refining and validating the design of SecureCPS.
