- Bruce Schneier (born January 15, 1963, pronounced /'?n???r/) is an American cryptographer, computer security specialist, and writer. He is the author of several books on computer security and cryptography, and is the founder and chief technology officer of BT Counterpane, formerly Counterpane Internet Security, Inc.
EducationOriginally from New York City, Schneier currently lives in Minneapolis, Minnesota. Schneier has a Master's degree in computer science from American University and a Bachelor of Science degree in physics from the University of Rochester. Before Counterpane, he worked at the United States Department of Defense and then AT&T Bell Labs. In August 1999, Schneier founded Counterpane Internet Security. Counterpane was acquired by BT in October 2006, and is now known as BT Managed Security Solutions. Schneier is currently the Chief Security Technology Officer of BT.
Writings on cryptographySchneier's Applied Cryptography is a popular reference work for cryptography. Schneier has designed or co-designed several cryptographic algorithms, including the Blowfish, Twofish and MacGuffin block ciphers, the Helix and Phelix stream ciphers, and the Yarrow and Fortuna cryptographically secure pseudo-random number generators. Solitaire is a cryptographic algorithm developed by Schneier for use by people without access to a computer, called Pontifex in Neal Stephenson's novel Cryptonomicon. In October 2008, Schneier, together with seven others, introduced the Skein hash function family, which has been submitted to the NIST hash function competition.
However, Schneier now denounces his early success as a naive, mathematical, and ivory tower view of what is inherently a people problem. In Applied Cryptography, he implies that correctly implemented algorithms and technology promise safety and secrecy, and that following security protocol ensures security, regardless of the behavior of others. Schneier now argues that the incontrovertible mathematical guarantees miss the point. As he describes in Secrets and Lies, a business which uses RSA encryption to protect its data without considering how the cryptographic keys are handled by employees on "complex, unstable, buggy" computers has failed to properly protect the information. An actual security solution that includes technology must also take into account the vagaries of hardware, software, networks, people, economics, and business. Schneier is now referring people trying to implement actually secure systems to his new book with Niels Ferguson, Practical Cryptography.
