[math-fun] Warren D Smith video lecture: How I broke AES -- if I did it
hmm. Did not realize I'd been videod+internetted. Hope it came out well. The paper that lecture was based on, can be read here: http://rangevoting.org/WarrenSmithPages/homepage/works.html paper#100 and it described what I called an alleged "nonconstructive break" of the AES cryptosystem. Later an alleged "genuine break" of AES was produced: http://research.microsoft.com/en-us/projects/cryptanalysis/aesbc.pdf but both theirs and mine have no real practical impact. My paper however also cited a "(cheating) break" of AES by Daniel J. Bernstein which I think is very serious practically speaking.
The new Intel AES instructions fix the Bernstein attack. The problem was actually noticed by [?] before Rijndael was adopted as AES, but didn't come to the attention of crypto folks. Bernstein's contribution was to carry out a simplified version of the attack, showing it was a real problem. Rich ---- Quoting Warren Smith <warren.wds@gmail.com>: <clip>
