$350 Hardware Cracks HDMI Copy Protection

[wraggster]

"German Researchers at the Ruhr University Bochum built an FPGA board-based man-in-the-middle attack against the HDCP copy protection used (http://aktuell.ruhr-uni-bochum.de/pm2011/pm00386.html.en) in HDMI connections. After the leak of an HDCP master key (http://entertainment.slashdot.org/story/10/09/14/1211205/hdcp-master-key-revealed) in 2010, Intel proclaimed that the copy protection was still secure (http://hardware.slashdot.org/story/10/09/17/0247246/hdcp-master-key-is-legitimate-blu-ray-is-cracked), as it would be too expensive to build a system that could conduct a real-time decryption of the data stream. It has now been proven that a system can be built for around $350 (€200) to do the task. However, the solution is of no great practical use for pirates. It can easily be used to burn films from Blu-ray discs, but receivers which can deliver HDTV recordings are already available — and they provide the data in compressed form. In contrast, recording directly from an HDMI port results in a large amount of data
