A comprehensive overview of privacy and security issues in deep space networks

The National Aeronautics and Space Administration (NASA) Deep Space Network (DSN), managed by the Jet Propulsion Laboratory's Interplanetary Network Directorate, is a critical international network facilitating communication for interplanetary spacecraft missions, radio astronomy, radar astronomy, and related observations. As the largest and most sophisticated telecommunications system globally, the DSN ensures vital communication and data transmission for space missions. This paper provides a comprehensive overview of the DSN's historical development, technical capabilities, and key facilities, emphasizing its essential role in past, present, and future space missions. It also addresses significant privacy, security, and performance issues within the network, evaluates current solutions, and identifies unresolved challenges and future research opportunities. The study reveals that while considerable advancements have been made, emerging threats and the evolving landscape of space exploration necessitate continuous improvements in security measures. The findings underscore the importance of innovative solutions to maintain the DSN's reliability and security, ensuring its effectiveness as a communication network for future space exploration.
