Warren: I really enjoyed the video, even though in high def the slides & the board are often unreadable. Your Matsui/Smith attack is really cool & is worth teaching -- whether or not it works in practise -- because it brings together a number of important concepts in coding theory in a cool way. If you still have the slides & want to link to the video on your own web site, it might be nice to make the slides available for better reading. At 04:47 PM 1/18/2012, Warren Smith wrote:

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:

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:

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.
