"The Code War," by Dana Mackenzie. Beyond Discovery, 12 February 2003.
The National Academy of Sciences commissions extended articles on recent technological advances and publishes them in its Beyond Discovery series. The newest mathematics article, "The Code War," describes modern encryption techniques that originated in number theory. The article is recent enough to include the result on the complexity of primality testing. Mackenzie wrote the article with assistance from Ron Graham, Arjen Lenstra, Barry Mazur, Andrew Odlyzko, Carl Pomerance, Kenneth Ribet, and Moses Liskov. Along with the text are a timeline, glossary and links to related sites.
