But aren't we (and the NSA) discovering new attacks all the time? So hence, their de facto security decays.
- marcosdumay 10y agoYes, that's improved math. All the time is a bit of an exaggeration. Some algorithms are broken very fast, others slowly accumulate partial attacks until people don't trust them anymore. Those last ones don't normally get completely broken¹. I think the only exceptions were the shorter key lengths of RSA². 1 - But you will find many examples of algorithms with less than the modern strength parameters that were broken by the mix of faster computers and partial attacks. 2 - But by the time those were abandoned people were mostly using even shorter keys that wouldn't suffice by today's standards even without any known attack.
