This article details a practical implementation of post-quantum cryptography within IPsec tunnels, specifically comparing the performance and mechanics of ML-DSA signatures against classical ECDSA in an IKEv2 handshake. By isolating the authentication layer while maintaining a hybrid key exchange, this work provides essential benchmarks for integrating quantum-resistant algorithms into existing network infrastructure without disrupting current security protocols.

strongSwan helps Cisco build a test for post-quantum IKEv2 security

This installment details mutual authentication over IKEv2, comparing classical ECDSA on strongSwan with the ML-DSA algorithm—a step toward building post-quantum IPsec tunnels.

Two Docker containers are now demonstrating mutual authentication over IKEv2, offering a self-contained lab environment accessible with only Docker. Julio Gomez is testing the post-quantum algorithm ML-DSA on an experimental branch of strongSwan, comparing it to ECDSA. This setup utilizes a single, small Certificate Authority spun up specifically for the lab, with each peer sending only its leaf certificate during the handshake, a strategy to minimize on-the-wire bytes, a concern amplified by larger post-quantum certificates as shown in Part 7. strongSwan’s latest validation of ECDSA for baseline IKEv2 authentication provides a crucial benchmark against which to measure the…
