draft-TR 33.880 (SA3)
Study on Mission Critical Security Enhancements

|   ToC   |   3GPP‑Page   |   Help   |

(W-zip) V1.4.0    2017/08    83 p.

Rapporteur:  Mr. Haigh, Peter
See also:  MCX-related TS/TR    

This document contains a study of the security aspects of the Mission-Critical service. It enhances the security solutions defined for MCPTT in TS 33.179 to support the common functional architecture (MC_ARCH), enhancements to MCPTT (eMCPTT), data services (MCData), video services (MCVideo), migration and interconnect services with partner systems (MCSMI), and interworking with non-LTE systems (MCCI).

In each case, this study includes an analysis of the threats to the service, the security requirements to mitigate those threats and an evaluation of possible technical solutions designed to meet the security requirements of the service.
