IKEv2 & WireGuard with NIST Post-Quantum ML-KEM-768

Securing WAN backbones against 'Harvest Now, Decrypt Later' adversaries using hybrid post-quantum key exchange.

The 'Harvest Now, Decrypt Later' Threat to Long-Haul WANs

Foreign intelligence services routinely record encrypted WAN fiber traffic, storing ciphertext until cryptanalytically relevant quantum computers (CRQC) can break standard RSA and ECC key exchanges. WanHSM eliminates this existential threat today by executing hybrid post-quantum key agreement inside hardware enclaves.

Hardware Acceleration of ML-KEM in IKEv2

Executing post-quantum lattice mathematics (FIPS 203) can slow software tunnel negotiation by orders of magnitude. WanHSM includes dedicated polynomial multiplier coprocessors that compute ML-KEM-768 key encapsulation in under 45 microseconds, enabling instant tunnel re-keying.

Hybrid Key Agreement: Combining classical ECDH (Curve25519) with lattice-based ML-KEM-768 in a single handshake.
RFC 9370 Compliance: Native hardware implementation of multiple key exchanges in Internet Key Exchange (IKEv2).
Hitless Re-Keying: Seamless session key rotation every 60 minutes without dropping a single in-flight packet.
Quantum-Safe Transit: Neutralizing adversary recording of trans-oceanic fiber traffic for future quantum decryption.
