ADS-B Safety & Security: ICAO ANC/11 WP/73 Summary by Sweden Air Navigation Services

This document presents a summary of the Positive and Negative Operational Aspects (Position & Intent) of ADS-B technology by Sweden Air Navigation Services Department. It covers the benefits such as "more eyes" surveillance, automated intent reporting, and direct detection without aircrew involvement. However, challenges like data link issues, user authentication, integrity, and confidentiality are discussed. The document explores potential solutions including position authentication mechanisms, independent position verification, built-in encryption, and two-way authentication exchange protocols. Real-time bandwidth constraints are also highlighted to emphasize the importance of robust security measures.
