Testing, Measuring and Managing PQC Migration

The Hidden Cost of Quantum-Safe Security and How to Plan PQC Migration

Modern systems depend on classical cryptography, but emerging quantum computers will eventually break these protections, making a shift to quantum‑safe methods like PQC and QKD essential—and far more complicated than it appears.

While standards such as NIST’s new PQC algorithms suggest an easy transition, real-world deployment introduces major performance and infrastructure challenges that can only be understood through large‑scale, realistic testing. Using VIAVI TeraVM Security Test, researchers simulated millions of PQC‑enabled TLS and IKEv2/IPsec connections to evaluate how components like HAProxy and Strongswan behave under enterprise‑level load, revealing the true operational impact of PQC adoption.
