Explains Reg: "Computer scientists in the Secure Hardware Group at Germany's Ruhr University built a custom board using relatively inexpensive FPGA chips. A Xilinx Spartan-6 FPGA featuring an HDMI port and a serial RS232 communication port was created and sat between a Blu-ray player and a flat screen TV, intercepting and decrypting traffic, without being detected."
Altogether, the board cost professor Tim Güneysu and PhD student Benno Lomb just $250.
Of course, the board itself is not practical for pirates who already take the content from receivers and discs.
Adds Güneysu:
Our intention was rather to investigate the fundamental security of HDCP systems and to measure the actual financial outlay for a complete knockout. The fact that we were able to achieve this in the context of a PhD thesis and using materials costing just ?200 is not a ringing endorsement of the security of the current HDCP system."
