We build a real hybrid IKEv2 tunnel in two Docker containers, capture the packets, and run classical versus hybrid side by side, seeing the extra round trip, ML-KEM fragmentation, and that going quantum-safe costs almost nothing.
While no one has yet built a general purpose Quantum Computer (QC) capable of breaking the public key cryptography in use on the Internet, that possibility is now considered a realistic threat to long-term security. As research into the design of a
Cisco developed Next Generation Encryption (NGE) in 2011. NGE was created to define a widely accepted and consistent set of cryptographic algorithms that provide strong security and good performance for our customers. These are the best standards that
