Hmm, how does flipping bits reveal the key? How are they able to control which bits get flipped? From the original article: Although this paper only discusses the problem, the professors say they've identified a solution. It's a common cryptographic technique called "salting" that changes the order of the digits in a random way every time the key is requested.This is kind of silly, because as far as I understand it they've already shown that a lot of things you would use encryption for (passwords) are vulnerable if you don't salt. It's interesting that this is a new type of attack though. Reply to this |
