Recent & Upcoming Talks

At IETF 115, we presented the latest work on the LDACS draft in version draft-ietf-raw-ldacs-13. After one other update, the draft was adopted by the IESG in December 2022.

The L-band Digital Aeronautical Communications System (LDACS), the worldwide first true integrated Communication, Navigation and Surveillance (CNS) system, is in the process of being standardized at the International Civil Aviation Organization (ICAO) and the Internet Engineering Task Force (IETF). The cellular system is considered a successor to the 30-years old Very High Frequency (VHF) Datalink mode 2 system (VDLm2) and intended for communications related to the safety and regularity of flight. With the initial rollout planned in the near future, the finalization of all its aspects, including security is of utmost importance. While previous works presented a cybersecurity architecture for LDACS, including a Public Key Infrastructure (PKI), certificates, a Mutual Authentication and Key Establishment (MAKE) procedure, as well as usage of established keys for protecting its user- and control-data plane, the protocol for secure LDACS handovers between cells has not been established. The objective of this work is to present a secure handover procedure for LDACS, fulfilling all security and performance requirements for data- and voice communications via LDACS.

In IETF 110 we mainly talk about security aspects of LDACS. We introduce the LDACS PKI, certificates, mutual authentication and key establishment schemes for LDACS, user-data protection and control-data protection concepts and close with a draft final call to the WG.

In IETF 109, after having passed adoption by the working group, we incorporated all the feedback we received from the group and mostly worked on clarifying the objectives for LDACS.

At 39th DASC 2020 we are going to present a comparison of different key exchange methods and find out which one is the best suited method for LDACS.

In IETF 108 we are going to present the latest and greatest about LDACS development and ask for adoption of our draft.

This talk provides an overview of the architecture of the L-band Digital Aeronautical Communications System (LDACS), which provides a …
