This report examines the feasibility of using modern cryptographic tools to improve space situational awareness. Specifically, the authors examine the applicability of secure multiparty computation (MPC) protocols as a means to compute the collision probability of two satellites. MPC protocols would provide satellite operators with a way to compute such "conjunction analyses" while maintaining the privacy of each operator's orbital information.
