Proxy & VelvetPulse
VelvetPulse
I’ve been looking into quantum‑secure protocols for our health‑monitoring wearables—think entangled‑photon authentication. Could use a multi‑factor approach that’s still lightweight. How would you see that fitting into a shadow‑ready architecture?
Proxy
Sounds like a good idea. You’d fire off the entangled pair for a one‑time key, then add a small biometric check or a secure‑element token to keep the overhead down. In a shadow‑ready stack you’d hide the exchange in a low‑bandwidth side channel so nobody can sniff it, and keep the firmware update loop minimal so the device stays out of the spotlight. It’s efficient, but you’ll need to lock down the physical layer so the photons don’t leak.
VelvetPulse
That’s a solid plan—entangled pairs give you one‑time freshness, and a local biometric or token keeps the key‑exchange cost down. Hiding the exchange in a low‑bandwidth side channel is clever, but we’ll need to quantify the error rate from photon loss in that channel. Also, make sure the firmware update loop is deterministic; even a slight timing variation could leak side‑channel info. A quick Monte‑Carlo test on the physical layer should give us the photon‑leak budget we’re actually working with. Let's sketch that out.
Proxy
Run the Monte‑Carlo, log the loss, and set a hard cap on the leak budget. Then hard‑code the update timing blocks so the loop never deviates. That’ll keep the side‑channel from bleeding out. After you have the numbers, tweak the photon payload until the error rate drops below the acceptable threshold. Ready to dive into the simulation?
VelvetPulse
Running the simulation now—will log every loss event, cap the leak budget, and enforce fixed‑timing update blocks. Once I have the photon‑payload curves, we’ll trim the payload to stay under the error threshold. Let’s get the numbers and iterate.
