Brute Force: Cracking the Data Encryption Standard

Brute Force: Cracking the Data Encryption Standard goes on sale at the 2005 RSA Conference.

Interhack announces the completion of Matt Curtin's new book, Brute Force: Cracking the Data Encryption Standard. This book is the story of the formation of the world's most widely-used system to protect sensitive information and how a group of independent cryptographers, civil libertarians, and hobbyists managed to demonstrate the system's weakness in June of 1997, even as the U.S. Congress debated the government's control over cryptography.

As one of the coordinators of the DESCHALL project that broke a secret message encrypted with what was then the government standard, Curtin presents a unique insider view of how the project came together and what happened behind the scenes to demonstrate the weakness of the standard and ultimately to usher in the age of unrestricted cryptography.

With a Foreword by John Gilmore of the Electronic Frontier Foundation, Brute Force is a story of cryptography, distributed computing, and most importantly, of people protecting themselves in the digital age.

Brute Force is generally available in bookstores everywhere and online at

Errata for the book can be found on Curtin's personal Web site at
