CAAs (Civil Aviation Authorities) worldwide have initiated rule making for UAS (Unmanned Aircraft Systems) RID (Remote Identification). 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 (formerly the American Society for Testing and Materials) WK65041 [1].  Network RID defines a set of information for UAS to make available globally indirectly via the Internet. Broadcast RID defines a set of messages for UA (Unmanned Aircraft) to send locally directly one-way over Bluetooth or Wi-Fi. WK65041 addresses how to neither populate/query registries, ensure trustworthiness of information nor make it instantly useful.
 
TMRID’s goal is to make RID immediately actionable, in both Internet and local-only connected scenarios, especially emergencies, in severely constrained UAS environments [2], balancing legitimate (e.g. public safety) authorities’ need to know trustworthy information with UAS operators’ privacy. TMRID potentially could be applied to verifiably identify other types of registered things reported to be in specified physical locations, but the urgent motivation and clear initial focus is UAS.
 
The  working group will primarily leverage solutions based on HIP as well as the domain name registration and focused on NPRM (Notice of Proposed Rule-Making) [3] published by US FAA (United States Federal Aviation Administration) as well as European CAA.
