I've written a brief paper which can be found at http://www.angelfire.com/realm/keith...CPAttacks.html which details four specific vunerabilities in the HDCP copy-protection scheme.

Any CRT-based display device, even an HDCP-compliant one, is going to have to ultimately put analog R G & B video signals through some kind of analog video amps to drive the CRT. It's not trivial, but it wouldn't be much of a deal for a competent video EE to tap into these |

Well, there are of course non-CRT options, like DLP and D-ILA. Aren't they digital all the way to the chip |
I don't want to get into the business of breaking security schemes. But the thing to remember is that you don't try to break the scheme by a frontal, brute-force approach based on the astronomical mathematics; you want to find some side approach that will exploit an unexpected fault |
