Drone Remote ID Protocol (DRIP) WG
================================

[previously TMRID BoF and tm-rid@ietf.org mailing list]

Civil Aviation Authorities (CAAs) worldwide have initiated rule making for
Unmanned Aircraft Systems (UAS) Remote Identification (RID). CAAs currently
promulgate performance-based regulations that do not mandate specific
techniques, but rather cite industry-consensus technical standards as
acceptable means of compliance. One key standard is ASTM International
(formerly the American Society for Testing and Materials) WK65041 [1]. This
technical specification defines UAS RID message formats, and transmission
methods. Network RID defines a set of information for UAS to be made available
globally via the Internet. Broadcast RID defines a set of messages for UAS to
send locally one-way over Bluetooth or Wi-Fi. WK65041 does not address how to
populate/query registries, how to ensure trustworthiness of information, nor
how to make the information useful.

DRIP’s goal is to specify how RID can be made available in both Internet and
local-only connected scenarios, especially in emergency situations. Some UAS
operate in environments where the network or the devices or both are severely
constrained [2] in terms of processing, bandwidth (e.g., Bluetooth 4 beacon
payload is 25 bytes long), or battery life, and DRIP aims to function in these
environments. The specifications produced by the WG will need to balance public
safety authorities’ need to know trustworthy information with UAS operators’
and other involved parties’ privacy.

The working group will primarily leverage Internet standards (including HIP,
EPP, RDAP, and DNS) and infrastructure as well as domain name registration
business models. The WG will track and align with the requirements being
developed by regulatory authorities, e.g., the US Federal Aviation
Administration (US FAA) [3] and the European Union Aviation Safety Agency
(EASA) delegated [4] and implementing [5] Regulations.

The working group will work on the following items:
* Requirements: the WG is expected to provide an informational document that
lists the technical requirements for applying IETF protocols to the UAS Remote
Identification (UAS RID) - that is the system for identifying UA during flight
by other parties. These requirements will also include those associated to the
UAS Identifier that need to both meet some constraints as well as some specific
properties. * Architecture: the WG will propose a standard document that
describes the architecture that address the technical requirements and that
will attempt to re-use protocols or architectures already standardized at the
IETF. * Protocol design: while the primary purpose of DRIP WG is to leverage
existing protocols, the specificities of the UAS environment are likely to
require existing protocols to be extended or new protocols to be designed. The
WG will focus on getting these protocols or extensions standardized,
coordinating with other WGs relevant for the protocol(s) in question on the
most appropriate home for any given piece of work.
