Space Cyber Architecting Horizons

摘要

Space Cyber "technology horizons" were introduced at AIAA Space 2011. Since then, additional architecting work has been accomplished which builds on the technology horizons effort. This additional architecting work is based on the idea that as we approach a fully Internet Protocol (IP) enabled spacecraft, we need to consider spacecraft as a network of enabled devices. New space architectures to be built on IP include hosted payloads, fractionated space architectures, and cube-satellites (cubesats). Many of these architectures will depend on standard based IP networking, which will make cluster assembly, and inter communication among the cluster modules akin to wireless communication on ground enterprises (WiFi). While this modularity brings multiple capabilities and advantages such as flexibility and robustness, IP-enabled satellites will introduce some cyber challenges, since cyber for IP enterprises is fairly advanced. This paper studies the cyber challenges from the perspective of the critical Space-Cyber talent needed to be successful in this endeavor. We draw parallels from existing enterprises and explore how they relate to IP-Enabled Space enterprises. Furthermore, we suggest some high-level approaches that improve the inherent architecting and design capabilities in order to achieve enhanced cyber resilience. We specifically highlight key activities that move us forward in the space-cyber area. These include the planning and hosting of the Malware TEM at The Aerospace Corporation (Aerospace), a wireless cyber project that we collaborated on with Harvey Mudd College, and some test beds that support the space cyber mission. We conclude with future work that will enhance our progress going forward.
