Securing IPX Roaming Exchanges and Cross-Border Telecom Transit

Establishing zero-trust cryptographic architectures for IP eXchange (IPX) service providers and clearinghouses.

Securing the IPX Roaming Ecosystem

IP eXchange (IPX) hubs connect over 800 global mobile operators. Compromising an IPX hub grants surveillance access to hundreds of millions of mobile users. TeleHSM implements zero-trust microsegmentation within IPX switches, ensuring that each operator's traffic travels within isolated, hardware-encrypted cryptographic tunnels.

Cryptographically Sealed Roaming Clearing

To prevent inter-carrier billing disputes and financial fraud, TeleHSM digitally signs TAP3 and BCE (Billing and Charging Evolution) clearing records at the exact moment of cross-border call handover, producing immutable audit evidence for international settlements.

Multi-Tenant Peering Enclaves: Cryptographically isolating roaming traffic between competing mobile network operators.
Automated Roaming Key Exchange: Dynamic distribution and rotation of inter-carrier encryption keys via GSMA PKI.
DDoS Defense on Signaling Links: Hardware rate-limiting preventing signaling flood attacks on core telecom elements.
Tamper-Evident Billing Mediation: Digitally signing Call Detail Records (CDRs) and TAP3 roaming clearing files.
