Abstract
Aircraft equipped with satellite communication (SATCOM) systems will enable advanced Air Traffic Management (ATM) operations over datalink on a global basis. A key concept of future ATM is 4D trajectory management, which aims to ensure an optimal path and designated arrival time for the
flight by integrating time as a fourth dimension into the aircraft
trajectory. However, the increase reliance on digital information
exchange needed for implementing 4D implies that cyber security
will be a key concern. The goal of the Iris Service Evolution
programme is to provide a secure and reliable datalink for airground
communication in oceanic and remote environment based
on satellite. This paper provides an overview over ongoing work
on cyber security in the Iris programme. We discuss the need
for security for future datalink services in the aircraft control
domain and, based on a security risk and threat analysis, provide
a number of security requirements that future SATCOM datalink
systems for ATM should fulfil.
