SEPP 2.0

Technical Explanation

When a user roams from Operator A to Operator B, all signaling traverses the N32 interface between their edge proxies. SEPP 2.0 inspects, filters, and encrypts all cross-carrier traffic using Post-Quantum Cryptography (ML-KEM/ML-DSA). It enforces strict JSON/Protobuf Web Token validation, performs application-layer message filtering, and sanitizes headers to prevent malicious operators from injecting malicious core commands.

Key Functions

• Cryptographic security gateway protecting inter-operator N32 roaming interconnects
• Post-Quantum mutual TLS and message-level encryption protecting cross-carrier signaling
• Application-layer firewalling detecting and blocking malformed or hostile core requests
• Cryptographic masking of internal network topology details from foreign carriers
• High-throughput line-rate filtering handling millions of roaming sessions concurrently
