Digital Fortress
Digital Fortress is a novel by American author Dan Brown and published in 1998 by St. Martin's Press
Susan Fletcher, a brilliant mathematician and head of the National Security Agency's (NSA's) cryptography division, finds herself faced with an unbreakable code resistant to brute-force attacks by the NSA's 3 million processor supercomputer dubbed "TRANSLTR". The code is written by Japanese cryptographer Ensei Tankado, a sacked employee of the NSA, who is displeased with the agency's intrusion into people's privacy. Tankado auctions the algorithm on his website, threatening that his accomplice "North Dakota" will release the algorithm for free if he dies. Tankado is found dead in Seville, Spain. Fletcher, along with her fiancé, David Becker, a skilled linguist with eidetic memory, must find a solution to stop the spread of the code.
