This report examines the feasibility of using modern cryptographic tools to improve space situational awareness. Specifically, the authors examine the applicability of secure multi-party computation (MPC) protocols as a means to compute the collision probability of two satellites. MPC protocols woul...

The primary purpose of the Programming Computation on Encrypted Data (PROCEED) program is to improve the efficiency of algorithms that allow people to carry out computations on encrypted data—without having to decrypt the data itself. RAND was asked to evaluate whether PROCEED—which expands the know...

Satellite anomalies are mission-degrading events that negatively affect on-orbit operational spacecraft. Maintaining a widely accessible and comprehensive database is one way to build an understanding of what situations are likely to result in satellite anomalies, but no such database exists. This r...
