BBN Technologies

Space Virtual Private Networking (SpaceVPN) is a multi-Satellite Virtual Private Network for space-based applications. BBN is developing architectures and building experiments to test concepts for networks that allow researchers to access and control instruments on board satellites in space from their desks. These architectures can be used as part of NASA's Earth sensor web, as well as on robotic and human missions for detailed investigation of planets, moons, and small bodies in the solar system. Building on the Distributed Spacecraft Network, or Hi-DSN, and security protocols such as IPSEC, BBN provides an integrated set of radio transceiver capabilities and network protocols for establishing and maintaining communications among diverse spacecraft in multiple orbits, and for connecting orbiting satellites to aircraft and terminals on the ground. Through NASA's Advanced Systems Technology Program (AIST), BBN is helping to extend VPNs to space, providing authentication, access control, integrity, and confidentiality for space communications in new and innovative ways.
