Cryptology
CS440

Technical Books

• Handbook of Applied Cryptography, Menezes, van Oorschot, Vanstone, CRC 1997. (Comprehensive treatment of modern cryptography).
• Applied Cryptography, Schneier, Wiley, 1996. (Very applied, includes code.)
• Decrypted Secrets, Bauer, Springer, 2002 (3rd edition). (Extremely comprehensive treatment of classical cryptology up to the end of WWII)
• Modern Cryptography. Theory & Practice, Wenbo Mao, Prentice-Hall, 2004. (Excellent text on cryptography, solid mathematical foundations, and practical discussions.)
• Basic cryptanalysis (field manual, released by the army; many similar books are available at Aegan Park Press).
• Security Engineering, Ross Anderson, Wiley, 2008 (2nd edition). (Standard text on the subject. Partially available online.)

Historical and Popular Books

• The Codebreakers, David Kahn, Sribner, 1996. (Comprehensive history of cryptology.)
• Between Silk and Cyanide: A Codemaker's War, 1941-1945, Leo Marks, Free Press, 2000. (Cliffhanger account of Marks code-making work for British spies in Europe; compelling reading. Check out interview with Marks)
• The American Black Chamber, Yardley, Aegean Park Press. (Yardley was in charge of the American Black chamber which existed from 1917 to 1929. There also is a recent biography of Yardley by David Kahn entitled The Reader of Gentlemen's Mail).
• The Code Book, Simon Singh, Anchor, 2000. (Popular historical account of cryptology, with a fair amount of technical detail.)
• The Cuckoo's Egg, Cliff Stoll, Pocket Books, 1990. (Real life account of Stoll tracking down a hacker. Better than James Bond.)
• Cryptonomicon, Neal Stephenson, Harper, 2000. (Occasionally long-winded novel, containing accurate technical details.)
• The Man Who Broke Purple, Ronald Clark, Little Brown, 1977. (Biography of William Friedman, the father of modern American cryptography, and the story of how he broke Purple.)
• The Puzzle Palace, James Bamford, Viking, 1983. (The early history of the National Security Agency (NSA)).
• The Shadow Factory, James Bamford, Random House, 2009. (Bamford continues his story of the NSA post 9/11).
