| If a GPU can be used to decrypt..
..why hasn't someone come with a method for a GPU to ENcrypt as well?
Sounds like it may be time to have a box acting as an AP that, once (honest) clients have successfully connected, be able to auto-generate and update the new encryption every xx minutes?
Or, maybe its time the average Joe stops being so damned lazy about their access security... |

There may be some reason against your suggestion that I don't know about, but it really seems like a good idea. The whole point of modern cryptography is that encrypting is many orders of magnitude faster than decrypting without a key, and the obstacle to wider use has been computation time, so if the GPU is well suited to breaking crypto, it should make strengthening crypto trivial.
Even better would be a dedicated crypto chip as standard equipment on PCs. This was one goal of the "trusted computing" scheme, but unfortunately those chips deny the owner access to the root key, which makes it a DRM chip instead of security for the owner. But a variation of the concept, with owner control, could make wireless encryption as close to unbreakable as anything in use today. I think VIA has made one that fits the description. |
