Correct. It's also the difference between theoretical security for infinite time vs security for something like 10^30 years. Is it really worth changing tried and tested algorithms and implementations already in place?
- CodesInChaos 5y agoThe asymmetric encryption/key-exchange algorithms that survive large quantum computers are all quite experimental and each has at least one major downside compared to RSA and (EC)DH. Still I'd prefer them over QKD.
