An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says "You're all idiots", and pours two beers.

comment How can I add more rounds to AES?
I think it makes some sense that adding rounds to AES would increase its security, as weaknesses have been reported on reduced round variants. Bruce Schneier did say "I suggest AES-128 at 16 rounds, AES-192 at 20 rounds, and AES-256 at 28 rounds." This might just be an off the cuff remark, but it's Schneier.
comment What is the “Random Oracle Model” and why is it controversial?
If we built a function that generated a truly random number for new every input it saw and stored all input, output pairs, would that be a closer to a random oracle? Assume we have infinite storage.
comment Is AES-256 weaker than 192 and 128 bit versions?
Is that last sentence meant to imply Bruce Schneier doesn't understand cryptography?
