It’s been a little while since we talked about HDCP around here, but recent developments in the area of digital content protection are proving very interesting.

You might remember that the Master Key for HDCP encryption was leaked last year, just a short while after Intel said that the protection had been cracked. While Intel admitted that HDCP had been … Read the rest

The HDCP master key

Pastebin has the HDCP master key that we talked about in a post last week. This is the encryption protocol used for HDMI content protection on media such as Blu-Ray and High Definition cable television.

The master key array is a 40×40 set of 56-bit hex used to generate the key sets. You get one brief paragraph at the … Read the rest

Their reasoning for the second statement is that for someone to make this work they would need to produce a computer chip, not something that is worth the effort.

We question that logic. Not … Read the rest
