Interesting. For what algorithm & key size?
I'd love to quote this. I've heard it before but I don't remember the source.
- est31 7y agohttps://eprint.iacr.org/2013/635.pdf https://eprint.iacr.org/2013/635.pdf > Boiling all water on the planet (including all starfish) amounts to about 2^24 lakes of Geneva and leads to global security: 114-bit symmetric cryptosystems, 228-bit cryptographic hashes, 2380-bit RSA. This needs to be done 16 thousand times to break AES-128, SHA-256, or 3064-bit RSA. I think this paper isn't using Landauer's bounds though, but conventional computers. So maybe my claim was wrong, because we aren't 16 thousand times away from Landauer's bounds but millions [1].

- johndough 7y agoBut why the starfish.
- alfiedotwtf 7y agoBecause if you're already boiling the oceans, you probably won't have enough left over in the budget for marine conservation.
