TetsuoShima Posted May 1, 2006 Share Posted May 1, 2006 Last week, Princeton mathematics professor Ed Felten published a relatively practical examination and groundwork for the manner in which HDCP will be cracked. While it has been publicly known since 2001 that the HDCP encryption scheme is flawed, thanks to the work and academic paper "A Cryptanalysis of the High-Bandwidth Digital Content Protection System" produced by Scott Crosby et al, Felton's post details in simplified math and practical terms the inevitability of the system being broken. What Professor Felten makes clear is the fact that, due to obvious flaws in the HDCP encryption scheme, HDCP will not simply be cracked or bypassed, but entirely owned. The entire HDCP system relies upon a secret set of 1600 special numbers that form a 40-by-40 matrix. If these numbers are discovered, every conceivable HDCP license key can be produced. According to Professor Felten, this is "virtually certain" to happen in the next couple of years. Critical flaws in the HDCP copy-protection scheme revealed. So, they did it again, protect content with a useless protection system that is as good as defeated even before it is in use (see css)... Might as well leave it out completely then... thoughts?

Tenebrae Posted May 1, 2006 Share Posted May 1, 2006 You sometimes wonder whether the people that make it are: A. Genuinely stupid and/or incompetent. B. Mucking up on purpose so they can spend years upgrading, patching. C. Secretly on the side of the pirates. One of those MUST be true. Although, it has been observed that there isn't copy protection - just measures that make copying more difficult. Link to comment Share on other sites More sharing options...
