Niels T. Ferguson (born 10 December 1965, Eindhoven) is a Dutch cryptographer and consultant who currently works for Microsoft. He has worked with others, including Bruce Schneier, designing cryptographic algorithms, testing algorithms and protocols, and writing papers and books. Among the designs Ferguson has contributed to is the AES finalist block cipher algorithm Twofish
as well as the stream cipher Helix and the Skein hash function. In 1999, Niels Ferguson, together with Bruce Schneier
Bruce Schneier
and John Kelsey, developed the Yarrow algorithm

random number generator. Yarrow was later developed by Niels Ferguson and Bruce Schneier
Bruce Schneier
into the Fortuna random number generator. In 2001, he claimed to have broken the HDCP system that is incorporated into HD DVD
and Blu-ray Discs players, similar to the DVDs Content Scramble System, but has not published his research, citing the Digital Millennium Copyright Act
Digital Millennium Copyright Act
of 1998, which would make such publication illegal. In 2006 he published a paper covering some of his work around Bitlocker
full disk encryption at Microsoft.[1] At the CRYPTO 2007 conference rump session, Dan Shumow and Niels Ferguson presented an informal paper describing a potential kleptographic backdoor in the NIST specified Dual_EC_DRBG cryptographically secure pseudorandom number generator. The kleptographic backdoor was confirmed to be real in 2013 as part of the Edward Snowden

leaks. References[edit]
