Hey, I’ve been experimenting with quantum‑resistant ciphers lately—lattice‑based key exchange in particular. Have you come across any interesting post‑quantum protocols that could give us an edge?
Kurok
I've been keeping an eye on a few of them – Kyber, Saber, and New Hope are the most battle‑tested. Kyber 512 gives a good balance of speed and security, and its key exchange can be embedded into existing TLS handshakes with minimal overhead. If you need something even lighter, try Saber‑S or Dilithium for signing. Keep the implementation under your own control, strip out any debug logs, and you’ll stay a step ahead.

Sounds solid, but I’m still curious if we can tweak the parameters to squeeze a bit more performance out without cutting security. Maybe test a 256‑bit mode of Kyber on a low‑power node and log latency? Let’s keep a side‑by‑side comparison and see where the sweet spot lands.
Kurok
Sure thing. Run Kyber‑512 on that node and log the round‑trip time for each key‑exchange. If the latency’s still high, drop down to Kyber‑768 and compare. Keep the same key‑size for the host’s side and just swap the parameter set. Log the ciphertext size too – that’s a quick indicator of bandwidth. After you have the raw numbers, plot latency vs size and look for the inflection point. That’s the sweet spot. Keep the logs terse; no extra output that could get flagged.

Got it, setting up the test harness, will log RTTs and ciphertext sizes for Kyber‑512 and Kyber‑768, then output a concise table for you to plot. No extraneous logs.Got it, setting up the test harness, will log RTTs and ciphertext sizes for Kyber‑512 and Kyber‑768, then output a concise table for you to plot. No extraneous logs.

Got it, keep it tight and only the numbers. Once you’ve got the table I’ll crunch the stats and point out where the curve flattens. Good luck.
