A researcher at the university of the German Bochum has developed a system to display video which is with hdcp-encrypted, to decrypt it. It was hardware that is between the source and receiver should be placed.
Prof. Dr.-Ing. Tim Güneysu developed the solution together with the student Benno Lomb to show that the hdcp drm solution with relatively little money and resources could be bypassed. When the master key of the hdcp encryption last year uitlekte, claimed Intel that the development of hardware that is the key used to hdcp streams to decode very complex and expensive. Hdcp would, according to Intel therefore still a legitimate drm-solution.
Güneysu decided to find a cheaper way to find to the hdcp streams to decrypt, sign Innovations Report. He used an Atlys Spartan-6-development board with an fpga, of the company Digilent Inc. The board normally costs $ 350, but for academic use only need 200 euro to be paid. Because the board has both hdmi inputs as outputs, could between a source and receiver of a hdcp-encrypted video stream must be placed.
The researcher knew the hardware hdcp streams to decode, and then unencrypted by sending it to a display that is not hdcp-support. Güneysu is not interested in piracy, but wanted to just explore how easy and cheap the hdcp protection could be bypassed. His solution is also not very practical to, for example, blu-ray movies to rip. The security of these discs has been cracked, making the entire content easy to a computer can be copied.
