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 trustworthy and 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 International Civil Aviation
Organization the European Union Aviation Safety Agency (EASA) delegated [3] and
implementing [4] regulations, and the US Federal Aviation Administration (US
FAA) [5].

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 Unmanned Aircraft
(UA) during flight by other parties. These requirements also include showing
that new or adapted identifiers from existing protocols conform and meet the
specifications to be certified as a UAS RID.

* 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.
