Quantum key distribution, end to end

Keys come from BB84: photons measured in randomly chosen bases, reconciled and privacy-amplified into an AES-GCM key. The photons are simulated — a channel model with attenuation, detector efficiency, dark counts and polarization misalignment — and everything above that model is the real protocol.

Both ends of the key exchange in this tab. No camera, no microphone, no second person.

A real call needs a pass and a second person. Connect above to enable it.
