4 Overview p. 8
TS 23.256 describes the architecture enhancements for supporting Uncrewed Aerial Systems (UAS).TS 23.256 contains the reference architecture and message flows to support this new functionality for UAVs. The present document describes the security of these new features including:
- Authentication and authorization of a Uncrewed Aerial Vehicle (UAV) with the UAS Service Supplier (USS) during 5GS registration;
- Authentication and authorization of a PDU session establishment and PDN connection establishment with the USS;
- Support re-authentication, re-authorisation and revocation of the above;
- Support for USS authorization of pairing of UAVs and UAV-Cs;
- Support for authorisation of providing location information and providing network based location to mitigate against UAVs reporting false location data;
- Support for security and privacy of Command and Control (C2) communications over PC5 interface in 3GPP system;
- Support for security and privacy of transporting Broadcast Remote Identification; and
- Support for security and privacy for Detect And Avoid (DAA) traffic.
