CD DRM: Attacks on Disc Recognition
Thursday January 26, 2006 by J. Alex Halderman

Ed and I are working on an academic paper, "Lessons from the Sony CD
DRM Episode", which will analyze several not-yet-discussed aspects of
the XCP and MediaMax CD copy protection technologies, and will try to
put the Sony CD episode in context and draw lessons for the future.
We'll post the complete paper here next Friday. Until then, we'll post
drafts of a few sections here. We have two reasons for this: we hope
the postings will be interesting in themselves, and we hope your
comments will help us improve the paper.

Today's excerpt is from the middle of the paper, where we're wading
through details about the copy protection systems and the techniques
they use to recognize protected CDs.

Please note that this is a draft and should not be formally quoted or
cited. The final version of our entire paper will be posted here when
it is ready.
