Architectural Layers & Silicon Defenses

Layer 1: High-Availability Carrier Gateway Silicon (PCIe Gen4 HSM / Dual Hot-Swap Power): Physically protecting roaming partner certificate hierarchies and carrier inter-connect root keys.
Layer 2: 5G SEPP N32 PRINS Encryption Engine (JSON Web Signature (JWS) / JWE Core): Executing Protocol for N32 Interconnect Security (PRINS), encrypting sensitive JSON attributes while allowing IPX routing.
Layer 3: Legacy Signaling Cryptographic Firewall (Deep Packet Inspection / MAP & Diameter): Validating cryptographic message provenance to block unauthorized location queries (SRI/ATI) and SMS redirection.
Layer 4: International IPX Peering & Core Transit (SCTP / Diameter / HTTP/2 Roaming Mesh): Terminating multi-gigabit IPX interconnect tunnels connecting global mobile operators and roaming clearinghouses.

Cryptographic Telemetry & Compliance: < 4 ms (N32-f JWE Encryption Latency) | 80,000/s (Diameter Message Filtering) | 100% (SS7 Location Spoof Defense) | GSMA FS.34 (5G Interconnect Certified)

Éliminer les vulnérabilités aux frontières télécoms internationales

International roaming exchanges and IPX hubs connect hundreds of mobile operators over legacy SS7 and Diameter signaling protocols plagued by location tracking, call interception, and SMS redirection exploits. TeleHSM establishes cryptographic hardware enforcement at operator network boundaries, securing 5G inter-carrier roaming via SEPP N32 encryption and cryptographically filtering legacy signaling messages.

Core Engineering Areas
