LBeee writes: German Researchers at the Ruhr University Bochum built a FPGA board based mand-in-the-middle attack against the HDCP copy protection used in HDMI connections.
After a leak of a HDCP master key in 2010, Intel proclaimed that the copy protection is still secure, as it would be too expensive to build a system that could conduct a real-time decryption of the data stream.
It is now proven, that a system can be built for around $350 (200 Euros), that can do the task. It is however, of no great practical use for pirates. It can be 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.
