The present document contains a study of the security aspects of enhancements to ProSe UE-to-Network Relay. Its objective is to identify threats when an Evolved ProSe Remote UE with UICC connects to the network via an Evolved ProSe UE-to-Network Relay. The potential requirements are identified based on threat and the potential solutions are studied. Evaluations of solutions are captured and the conclusion forms the basis for the potential normative work.
