Abstract
Mankind is actively trying to communicate with extraterrestrial life. However, historically the discovery of new civilizations has led to war, subjugation, and even elimination. With that in mind, we believe that for any attempted contact with extraterrestrials our location must not be revealed. Therefore, we focus on the problem of location-private interstellar communication. We approach this as a security problem and propose to work towards solutions with tools from the domain of secure communications. As a first step, we give proposals for adversary models, security requirements, and security controls.
