Automatic Dependent Surveillance Broadcast (ADS-B) is one of the most prominent air traffic surveillance technologies. It can be used not only as a complement in existing radar-based technologies to locate aircraft, but also as a replacement in areas without radar coverage. However, a major flaw in the deployment of this technology is it reliance on clear-text, open broadcast of messages, which makes it vulnerable to attackers. A solution to this vulnerability is ADS-Bsec, a holistic framework that solves the root cause of ADS-B problems by enforcing authenticity and integrity in ADS-B messages. This is accomplished without changing the message format and, along with a proper key exchange mechanism. The framework also leverages results from radio-location add risk-adaptive techniques in order to prevent attacks targeting ADS-B. ADS-Bsec is a promising framework for integrating ADS-B to NextGen infrastructure in a secure and affordable fashion.
