Architectural Layers & Silicon Defenses

Layer 1: Carrier-Grade NEBS Level 3 Hardware Enclosure (FIPS 140-3 L4 / Dual-Redundant DC Power): Physically protecting the telecom operator master secret keys (K) and Home Network Private Keys (HN-PK).
Layer 2: 3GPP 5G AKA & ECIES Cryptographic Core (Hardware MILENAGE / TUAK / ECIES Pipeline): De-concealing SUCIs and generating 5G AKA authentication vectors (RAND, AUTN, XRES*, K_AUSF) in under 8ms.
Layer 3: eSIM Remote SIM Provisioning (RSP) Engine (GSMA SGP.22 (Consumer) / SGP.32 (IoT)): Encrypting mobile operator profiles and issuing cryptographically bound Bound Profile Packages (BPP).
Layer 4: Service-Based Architecture (SBA) Gateway (HTTP/2 REST / OpenAPI 3.0 / mTLS Core): Connecting to 5G Unified Data Management (UDM) and Subscription Identifier De-concealing Functions (SIDF).

Cryptographic Telemetry & Compliance: 150,000/s (SUCI De-Concealment Rate) | < 8 ms (5G AKA Vector Generation) | 99.9999% (Carrier Six-Nines Availability) | GSMA SAS (Certified eSIM Security)

Protecting Billions of Connected Subscribers at Carrier Scale

In legacy 2G/3G/4G networks, unencrypted subscriber identities (IMSI) were broadcast over the air, enabling IMSI-catcher tracking and cellular surveillance. 5G Standalone solves this by encrypting identities into Subscription Concealed Identifiers (SUCI). TelecomHSM provides mobile operators with certified hardware modules that decrypt SUCIs, authenticate subscriber SIM credentials, and issue remote eSIM profiles at wire speed.

Core Engineering Areas
