电信互联边界网关专用 HSM 与 5G SEPP 互通加密金库

面向国际漫游转接中心、跨运营商 IPX 对等互联交换节点以及传统信令协议部署专用硬件加密防护设备，深度拦截窃听、定位伪造及计费欺诈攻击。

TeleHSM Inter-Carrier Gateway Architecture

Cryptographic Enclave: Telecom Interconnect Core — 5G SEPP / IPX Hardware Enclave

Hardware Security Nodes & Co-Processors

  • 5G SEPP N32-f Encryptor
  • SS7 / Diameter Cryptographic Filter
  • IPX Roaming Session Vault
  • SMS Home Routing Signer
  • Carrier Key Escrow & Audit Core

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)

消除国际电信边界的安全漏洞

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.
