Tactical Mapping: 3GPP Release 15 (5G Baseline)
This document provides the Tactical Realization of ITU Recommendations for 3GPP Rel-15 networks (5G Phase 1).
🏛️ Architecture & Core Security
- ITU Rec: Y.3101 (Requirements for IMT-2020)
- 3GPP Implementation: TS 23.501 (SBA) & TS 33.501 (Security Arch).
- Key Tactical Features:
- SEPP (Security Edge Protection Proxy): Realizes itu-t Q.3062 signaling integrity for inter-PLMN (N32) interfaces.
- AUSF (Authentication Server Function): Realizes itu-t X.1035 authentication requirements via 5G AKA.
- UPF (User Plane Function): Realizes itu-t X.805 dimension of Communication Security in the data plane.
🔐 Security Dimensions (X.805)
| Dimension | Rel-15 Technical Feature | 3GPP Spec |
|---|---|---|
| Authentication | 5G AKA / EAP-TLS | TS 33.501 |
| Confidentiality | NAS/RRC Ciphering (AES/SNOW/ZUC) | TS 33.401 |
| Integrity | User-Plane Integrity Protection (NR-IP) | TS 33.501 |
| Availability | AMF/SMF Load Control & Congestion | TS 23.502 |
| Privacy | SUCI (Subscription Concealed ID) | TS 33.501 |
📡 Radio Access Network (NR)
- ITU Rec: M.2150 (NR Security Map)
- 3GPP Implementation: TS 38.300 (NR Architecture).
- Tactical Focus: AS (Access Stratum) security, PDCP encryption, and secure bootstrap of gNB.
!TIPAudit Hint: When auditing for X.805 Confidentiality in Rel-15, verify the
NEA2(AES) implementation on the N1/N2 interfaces.
