I was thinking of something much more simple, time division and non geo geostationary.

Wrt proxy for entanglement based approaches the idea is the satellite would be an untrusted bell pair generator sending entangled pairs for parties to generate keys with

Btw Luke I’ve just sent you an email regarding a new attack analysis against BB84 I’ve been working on

Nice to chat here! You’re right about point to point during QKD of course. what would be the right phrase to describe that multiple receivers, even mobile, can perform QKD with the Sat, sequentially if not concurrently without multiplexing

There’s production * (typo)

I think the clearest argument is that it requires classical auth to start with. So why not just use classical authentication then ???

Regarding scalability there’s productive satellite QKD available now, so the last mile/ point to point argument does not apply there

Yeah when I first implemented that for WiFi wpa2/3 my thoughts were similar, but recently revisited this and can’t help but wonder if this helps create sidechannel points with known plaintext on the pattern that’s unwrapped

Do they also aid memory forensics/
Sidechannels for automated key discovery ?

Anti coercion act and statements from EU makes it seem like they’re a target for EU.

of the deficit something like 75% -80% is due to US related party import. Taxing US activity for production abroad would have been the better approach to avoid collateral damage to exports
