The present document specifies the security features in support of the architecture enhancements for supporting Uncrewed Aerial Systems (UAS) connectivity, identification, tracking and pairing authorization defined in
TS 23.256, according to the use cases and service requirements defined in
TS 22.125.
The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
-
References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
-
For a specific reference, subsequent revisions do not apply.
-
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

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; and
-
Support for authorisation of providing location information and providing network based location to mitigate against UAVs reporting false location data.
