To be fair, this is the theory that all security guarantees boil down to (excluding the "so it's uncrackable" part)
- beardedwizard 2y agoI would argue this extends to all systems and behaviors that aren't formally verified. Bugs notwithstanding, breaking current encryption is a mathematically backed concept. The issue is broken implementations.
- GTP 2y agoBut in cryptography, you have a security claim that is based on the hardness of a well known mathematical probelm. So you know that breaking a certain scheme is as hard as solving that problem. If someone finds out how to solve such a problem efficiently the scheme is broken, but as long as no one has a solution the scheme is safe. Here it is not clear to me what is the hard problem that makes this scheme secure. Yes, you have light scattering in a random way, but they also showed that it is possible to train a neural network to get the data back. Why can't an attacker do the same?
- bawolff 2y agoThere is a difference between - some random dude who invented the scheme can't figure out how to crack it - and - the entire mathematical world has been trying to figure it out for the last 2200 years (since Eratosthenes) and still haven't.
