1 Scope p. 6
The present document provides the security aspects for the 5G system to facilitate vehicular communications for Vehicle-to-Everything (V2X) services. The architecture for these V2X services is described in TS 23.287, which is based on the service requirements defined in TS 22.185 and TS 22.186.

4 Overview of advanced V2X security architecture p. 7
4.1 General p. 7
The V2X architecture is described in TS 23.287 which describes V2X communication over both the Uu reference point supported by E-UTRA connected to 5GC and/or NR connected to 5GC and PC5 reference point supported by E-UTRA and/or NR. The NR based PC5 reference point supports unicast, groupcast and broadcast modes (see TS 23.287).
The security for PC5 reference point supported by E-UTRA is given in TS 33.185. The security for the other cases is given in the present document.
