Study on isolated E-UTRAN operation for public safety; Security aspects
The present document contains the results of a Stage 2 study and evaluation of possible 3GPP security solutions in support of Isolated E-UTRAN Operation for Public Safety (IOPS). The solutions are based on the Stage 1 requirements in 3GPP TS 22.346 [2], the architectural enhancements to support IOPS presented in the Stage 2 study report 3GPP TR 23.797 [3] and resulting informative Annex K in 3GPP TS 23.401 [10]. For the current release of specification the solution in 3GPP TS 23.401 [10] is based on a Local EPC with no backhaul.
The present document identifies key issues, security threats, deduces security requirements and presents proposed security solutions for IOPS.
Throughout this Technical Report the terms 'IOPS network' and 'Isolated E-UTRAN' are used synonymously.
