But if the theory allows the attack, even if it seems impractical, there is likely to be a practical attack that is slightly different.

- enord 9y agoThis does not follow. Please elaborate. Theory allows a brute force attack on aes-256, no?
- inimino 9y agoOf course. Theory also allows us to exactly model the probability of such an attack succeeding. The difference between a system that is provably secure and a system that is theoretically insecure but with no known practical attack is a pretty big difference. In the former case, your proof has to be wrong before you lose, in the latter, someone just has to think of something you didn't.
- socrates1024 9y agoThis is a great explanation for why theory is valuable.
