Hello, I'll react to multiple questions and statements from multiple people. > A figure I heard was that qc can cut search time for symmetric key merely in > half, whereas its can cut time for asymmetric key by orders of magnitude.  No. For symmetric key, it does not halve the time. It works

Re: [qubes-users] Qubes & Quantum decryption Immunity

QC is a potential threat for both symmetric and asymmetric cryptography, just the symmetric cryptography is threatened quite a bit more. And even asymmetric cryptography is important for QubesOS security because of update signatures. Symmetric cryptography is threatened by Grover's algorithm.

Re: [qubes-users] Qubes & Quantum decryption Immunity

In this case you should ask the luks/dmcrypt mailinglist as that is what qubes uses for disk crypto. I doubt anyone here bar the internets favorite folk hero "kedward howden" would piss off some company/government enough for them to spend the hundreds of thousands of dollars one to rent such

[qubes-users] Qubes & Quantum decryption Immunity

With news, like the 50-bit Quantum computer by IBM announced earlier today, for now only cable to run over over 90 seconds, concerns over the safety of encryption appears to be slowly increasing.
