A Different Road to Quantum Safety: The PPK – IPsec Series, Part 5

A second road to quantum safety: a Postquantum Preshared Key mixes an out-of-band secret into the IKE key schedule that never travels the wire, so even a classical handshake resists "harvest now, decrypt later," on gear not supporting ML-KEM.
