Study on security issues to support Proximity Services (ProSe)
The present document contains a study of the security aspects of Proximity Services (ProSe) and an evaluation of possible technical solutions needed to support such services. The Stage 1 requirements for these services are defined in TS 22.278 [2] and TS 22.115 [3]. These requirements include a list of general requirements on ProSe Security, Authorization and Privacy (TS 22.278 [2] clause 9.4), which are taken into consideration when developing the security key issues, security requirements and security solutions in the present document.
Different possible Stage 2 solutions for Proximity Services are studied in TR 23.703 [4].
Normative provisions/requirements are included in the present specification solely for the purposes of studying solutions and are not to be considered as implying normative requirements on 3GPP entities.
NOTE: Lawful Interception (LI) aspects are not covered in this document.
