Markus Guenther Kuhn (born 1971) is a German computer scientist, currently teaching and researching at the University of Cambridge Computer Laboratory.[11][12][13][14][15]


Kuhn was educated at University of Erlangen (Germany), he received his Master of Science degree at Purdue University and PhD at the University of Cambridge. He is a Fellow of Wolfson College, Cambridge.


Kuhn's main research interests include computer security, in particular the hardware and signal-processing aspects of it, and distributed systems. He is known, among other things, for his work on security microcontrollers, compromising emanations, and distance-bounding protocols. He developed the Stirmark test for digital watermarking schemes, the OTPW one-time password system, and headed the project that extended the X11 misc-fixed fonts to Unicode.

In 1987 and 1988, he won the German national computer-science contest,[16] and in 1989, he won a gold medal for the West German team at the International Olympiad in Informatics.[17][18] In 1994, as an undergraduate student, he became known for developing several ways to circumvent the VideoCrypt encryption system, most notably the Season7 smartcard emulator.[19]

In 2002, he published a new method for eavesdropping CRT screens.[3]

In 2010 Kuhn was asked to analyze the ADE-651, a device used in Iraq that was said to be a bomb-detecting device; he found that it contained nothing but an anti-theft tag and said that it was "impossible" that the device could detect anything whatsoever.[20]

He is also known for some of his work on international standardization, such as pioneering the introduction of Unicode/UTF-8 under Linux.[21]
