Bruce Schneider's thermodynamic argument linked in the post (aka the Landauer principle[1]) shows clearly that there is not enough energy available in the solar system to feasibly brute force a 256 bit key.
So what exactly is being argued here then? That advances in computational tech will break the Landauer limit?
It seems more likely that the exponential growth of computational capacity will end soon.

- DVNC_Joseph 12y agoWhat is being argued is that understanding the relationship (which is linear) is more important and more useful than understanding the improbability.
- x1798DE 12y agoIt's not a straightforward linear relationship, though, it relies on exponential growth in computing power to a point past where physics allows it to go. I think you need a specific assertion as to how it will be possible to overcome the thermodynamics before you can make an affirmative claim that it is exponentially easier to brute-force AES than previously believed.
