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
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.

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.
