ETSI ETSI TS 133 303 V12.6.0 (2016-01)73GPP TS 33.303 version 12.6.0 Release 121 Scope The present document specifies the security aspects of the Proximity Services (ProSe) features in EPS. Based on the common security procedures (clause 5) for - interfaces between
38、network entities (using NDS), - configuration of ProSe-enabled UEs, and - data transfer between the ProSe Function and a ProSe enabled UE (PC3 interface) security for the following ProSe features is covered: - Open ProSe Direct Discovery in network coverage (clause 6.1); - One-to-many ProSe direct c
39、ommunication for ProSe-enabled Public Safety UEs (clause 6.2); - EPC-level Discovery of ProSe-enabled UEs (clause 6.3); - EPC support for WLAN Direct Discovery and Communication (clause 6.4). 2 References The following documents contain provisions which, through reference in this text, constitute pr
