Bruce Schneier ( //; born January 15, 1963) 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. He received his master's degree in computer science from the American University in Washington, DC in 1988.In 1994, Schneier published "Applied Cryptography", which details the design, use, and implementation of cryptographic algorithms. More recently he published "Cryptography Engineering", which is focused more on how to use cryptography in real systems and less on its internal design. He has also written books on security for a broader audience. In 2000, Schneier published Secrets and Lies: Digital Security in a Networked World. In 2003, Schneier published Beyond Fear: Thinking Sensibly About Security in an Uncertain World.
Schneier writes a freely available monthly Internet newsletter on computer and other security issues, Crypto-Gram, as well as a security weblog, Schneier on Security. The weblog started out as a way to publish essays before they appeared in Crypto-Gram, making it possible for others to comment on them while the stories were still current, but over time the newsletter became a monthly email version of the blog, re-edited and re-organized. Schneier is frequently quoted in the press on computer and other security issues, pointing out flaws in security and cryptographic implementations ranging from biometrics to airline security after the September 11 attacks. He also writes "Security Matters", a regular column for Wired Magazine.[4
Schneier revealed on his blog that in the December 2004 issue of the SIGCSE Bulletin, three Pakistani academics, Khawaja Amer Hayat, Umar Waqar Anis, and S. Tauseef-ur-Rehman, from the International Islamic University in Islamabad, Pakistan, plagiarized an article written by Schneier and got it published. The same academics subsequently plagiarized another article by Ville Hallivuori on "Real-time Transport Protocol (RTP) security" as well. Schneier complained to the editors of the periodical, which generated a minor controversy. The editor of the SIGCSE Bulletin removed the paper from their website and demanded official letters of admission and apology. Schneier noted on his blog that International Islamic University personnel had requested him "to close comments in this blog entry"; Schneier refused to close comments on the blog, but he did delete posts which he deemed "incoherent or hostile".
