Obviously this isn't the strongest argument in the world, but, if the whole field is so bullshit why has anyone bothered putting effort into post-quantum encryption? What's the point if quantum computers will never materialize?
- alexw91 6y agoIt's theoretically possible for someone to record encrypted traffic today, keep a copy of it for a decade or two until quantum computers are available, and then decrypt it in the future using the quantum computer. If you have data today, that needs to be secure for more than a few decades, you may want to move to post quantum crypto soon to stop that potential leak.
- haltingproblem 6y agoLets rephrase it in terms of product-market fit - what problem is post-quantum encryption going to solve for people to put effort into it? BTW, the term post-quantum encryption is delicious because we had never had the quantum encryption era. Like the post-high speed era rail in the US ;)
- caf 6y agoThe sense this term is using 'quantum' is as a shorthand for a point in time, where attacking cryptosystems using quantum computers becomes feasible. So you can talk ante-quantum and post-quantum in this sense, but it makes little sense to talk about just 'quantum', in exactly the same way that we schedule a lot of things AM and PM but very little for precisely noon.
