HDCP Break Proven

Scott Crosby of Carnegie Mellon University, Ian Goldberg of Zero Knowledge Systems, and Robert Johnson, Dawn Song, and David Wagner of UC Berkeley have published a formal cryptanalysis of the High-bandwidth Digital Content Protection System that proves its fatal flaws. Interesting reading for those with some background with cryptanalysis."

      If enough people are made to care and support liberty, then we can elect pro-liberty leaders and make the USA more free.

    Reading the document, the crack hinges on collecting a sufficient number of public keys. The solution is obvious:

    Ban the sharing of public keys!
    Oh, wait...
