MIL-STD-1553 is a widely used communications protocol in the military aircraft for many North Atlantic Treaty Organization (NATO) countries. The Department of Defence designed this protocol before the advent of cybersecurity, making it an easy target for malicious actors. Researchers have been working to find affordable ways to secure the communications bus using non-invasive means such as the addition of an Intrusion Detection System (IDS). Many of the researched IDS systems are calibrated using small-scale datasets which do not provide sufficient training data for complex IDS systems or use proprietary hardware systems that restrict access to researchers with strong financial incentive to perform this research. Other attempts to address this accessibility gap have produced slow and inaccurate simulations at both the bus level, and the terminal level. We propose a real-time MIL-STD-1553 bus simulator. The proposed simulator will be capable of replicating correct timing for message passing and response as well as supplying an extensible framework for building in custom attacks, schedules, and terminals.
