Security Enhancements of the Surveillance Data Exchange Protocol “ASTERIX”

Marián JANČÍK, Johannes DE HAAN, Petr JONÁŠ


The surveillance information are key data for all air navigation service providers which are responsible for the safety of the air passengers and the efficiency of Air Traffic Management system. In this paper, we have focused on the analysis of a protocol used to carry the surveillance information from the sensor to the ATC centre as well as amongst variety of ATM applications inside the ATC centre. As the original ASTERIX protocol has been developed without any security mechanism, it constitutes a major vulnerability. This deficiency has been acknowledged by the AMG (ASTERIX management group) which is seeking a remedy. In this article we describe a proposal to implement the security features into the protocol.
