the encryption that e.g. underlies routing security at multiple protocol layers from secure routing announcements to UDP to TLS and to the whole assurance and certification regime underlying SSL. But honestly this is just a wild guess. Who, that actually knows about (potential widespread future) quantum decryption, is thinking about how it might impact internet infrastrucrure, especially routing? Would be curious and grateful to know more (and where/if I'm wrong). 2/2

@mariafarrell@mastodon.social Dynamic changes might be easy to detect & counter, so shirt term. Keys for all that encrypted stolen data could have more strategic value. 2/2

@mariafarrell@mastodon.social same. I've wondered about this and have no idea even though I'm on the edge of projects that are actively making changes that are claimed to protect against quantum cryptography. So I have assumed there are measures available, but do not know if they are making their way into any of the places they are needed to protect web and internet, it anywhere else. It's Y2K with no date. Hoping you'll shed some light (and that your back is much better - walking the dog helps mine a lot).

@mariafarrell@mastodon.social Presumably it depends on three things: 1) Who has the technology 2) How fast it can work 3) What their goals are 1/2

@mariafarrell@mastodon.social I’m thinking the folks behind @internet_nl@mastodon.nl might have something meaningful to say about quantum x TLS/SSL

@mariafarrell@mastodon.social Me too. I am considering going back to using carrier pigeons at the moment. Perhaps the other things is how well will current encryption algorithms stand up the stupendous computing power that the data centres built to power AI now have. That is, ignoring the current state of AI and other future possible ways to attack encryption.

@mariafarrell@mastodon.social it's a while since I thought about this sort of thing so I am probably out of date. But the availability of pqc made me think that exploits at the transport layer will be fixable quickly, once it is widely known to be a problem. Knowing is, of course, a challenge, but it seems to me that gaining access to realtime data is only important if you are going to use it pretty soon, at which point you risk detection. I'm still concerned about encrypted data at rest though!
