@Malcolm Weir - Re: What's the problem?
I wouldn't bet my farm on AES, US did not adopt this algorithm because it's open. Nowadays when encryption is still considered as a competitive advantage for military and law enforcement, for US to gladly adopt an algorithm created without the benediction of their most trusted agencies looks suspect to me.

Then go on and read the Black Hat Europe presentation referenced in the article. It's eye opening.
