Censorship in action: why I don't publish my HDCP results
DMCA
'I have written a paper detailing security weaknesses in the HDCP content protection system. I have decided to censor myself and not publish this paper for fear of prosecution and/or liability under the US DMCA law.'

'My name is Niels Ferguson. I'm a professional cryptographer. My job is to design, analyse, and attack cryptographic security systems, a bit like a digital locksmith. I work to make computer systems and the Internet more secure. You would think that people would be in favour of that, right?'

Excellent paper. If Mr. Ferguson ever decides he doesn't want to be a cryptographer anymore, I'm sure he could find work as a writer. Clear, concise, comprehensible... the three C's.
