Writing on cryptography

Schneier's Applied Cryptography is a popular and widely regarded reference work for cryptography. Schneier has designed or co-designed several cryptographic algorithms, including the Blowfish, Twofish and MacGuffin block 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. General Designer(s) Bruce Schneier First published 1993 Derived from - Cipher(s) based on this design Twofish Algorithm detail Block size(s) 64 bits Key size(s) 32-448 bits in steps of 8 bits; default 128 bits Structure Feistel network Number of rounds 16 Best cryptanalysis Four rounds of... In cryptography, Twofish is a symmetric key block cipher with a block size of 128 bits and key sizes up to 256 bits. ... In cryptography, MacGuffin is a block cipher created in 1994 by Bruce Schneier and Matt Blaze at a Fast Software Encryption workshop. ... Encryption Decryption In cryptography, a block cipher is a symmetric key cipher which operates on fixed-length groups of bits, termed blocks, with an unvarying transformation. ... The Yarrow algorithm is a cryptographically secure pseudo-random number generator. ... Fortuna is a cryptographically secure pseudo-random number generator (PRNG) devised by Bruce Schneier and Niels Ferguson. ... A cryptographically secure pseudo-random number generator (CSPRNG) is a pseudo-random number generator (PRNG) with properties that make it suitable for use in cryptography. ... The Solitaire cryptographic algorithm was designed by Bruce Schneier for use in Neal Stephensons Cryptonomicon (where it was initially called Pontifex). ... Flowcharts are often used to graphically represent algorithms. ... Neal Town Stephenson (b. ... Cryptonomicon is a 1999 novel by Neal Stephenson that concurrently follows the exploits of World War II-era cryptographers affiliated with Bletchley Park in their attempts to crack Axis codes and fight the Nazi submarine fleet, alongside the story of their descendants, who are attempting to use modern cryptography to...

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. Academic institutions often face the charge of academic elitism, sometimes called the Ivory Tower. ... In cryptography, RSA is an algorithm for public-key encryption. ... Niels Ferguson is a Dutch cryptographic engineer and consultant. ...

Schneier writes a freely available monthly Internet newsletter on computer and other security issues, Crypto-Gram, as well as a security blog [2] . He is frequently quoted in the press on computer and other security issues, pointing out flaws in security and cryptographic implementations ranging from biometrics to the post-September 11 airline security measures.

Miscellaneous

Bruce Schneier is name-dropped in the blockbuster book The Da Vinci Code. Page 199 of the American hardcover edition states: This article is about the novel. ...

"Da Vinci had been a cryptography pioneer, Sophie knew, although he was seldom given credit. Sophie's university instructors, while presenting computer encryption methods for securing data, praised modern cryptologists like Zimmermann and Schneier but failed to mention that it was Leonardo who had invented one of the first rudimentary forms of public key encryption centuries ago."

The website geekz.co.uk features Bruce Schneier in a parody of Chuck Norris Facts called Bruce Schneier Facts featuring lines such as "Most people use passwords. Some people use passphrases. Bruce Schneier uses an epic passpoem, detailing the life and works of seven mythical Norse heroes." Phil Zimmermann is the creator of the popular PGP encryption software. ... Leonardo di ser Piero da Vinci (April 15, 1452 – May 2, 1519) was a talented Italian Renaissance Roman Catholic[1] polymath: architect, anatomist, sculptor, engineer, inventor, geometer, scientist, mathematician, musician, and painter. ...
