Bruce Schneier

Bruce Schneier ( born January 15, 1963 in New York) is an American expert on cryptography and computer security, author of several books on computer security and co-founder of the computer security firm Counterpane Internet Security.

Schneier is a Fellow of the Berkman Center for Internet & Society at Harvard Law School and the Open Technology Institute at the New America Foundation. He was brought by the British newspaper The Guardian in the editorial team, the surveillance and espionage in 2013 reveals due to the revelations of Edward Snowden. He is a board member of the Electronic Frontier Foundation.


Schneier was born in New York. After completing his bachelor's degree in physics at the Rochester University, where he studied from 1985 at the American University, where he received a master's degree in computer science. During his studies he started to work for the Department of Defense. Before he Counterpane Internet Security ( October 2006 acquisition by BT Managed Security Solutions Mountain View ) founded in August 1999, he worked at Bell Labs. Today Schneier lives with his wife Karen Cooper in Minneapolis.

When British Telecom, he holds the job title Security Futurologist.


His most famous work is Applied Cryptography, a fundamental work to get started with cryptography. Furthermore, there is a whole series of publications on computer security and cryptography. The newsletter Crypto -Gram about computers and other security issues will be sent to the subscribers monthly. Here, as in his blog current problems are addressed.

Schneier deals intensively with the development of encryption algorithms. In the appendix of the book Cryptonomicon ( Neal Stephenson ), he introduces the Solitaire encryption algorithm, which works with an ordinary deck of cards. He has the Blowfish and Twofish encryption algorithms, and Yarrow and Fortuna pseudo- random co-developed. Twofish came here with the shortlist of the AES competition. As part of the SHA -3 competition, he was one of the developers of the Skein hash algorithm.

Schneier explored in the episode reinforces broader issues of computer security, for dealing with risks and related to cryptography and computer security socio-political issues. Today he deals extensively with additional psychological information security issues, especially with the security awareness and attitude of users and experts.

In November 2007 he exhibited in the technology magazine Wired points out that in his view, in one of four published by NIST in March 2007 cryptographic random number generators, namely the Dual Elliptic Curve Deterministic Random Bit Generator ( Dual_EC_DRBG ), possibly a backdoor is installed. It is worth mentioning that the choice of this generator is to be done for the standardization mainly due to the insistence of the NSA. This random number generator is also included with Service Pack 1 in Windows Vista.
