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.
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.
Is AES-256 weaker than 192 and 128 bit versions?
Is that last sentence meant to imply Bruce Schneier doesn't understand cryptography?
