Reviews

From the reviews: An excellent story about the thousands of volunteers who battled to prove that the aging standard for date encryption was too weak and to wrestle strong cryptography from the control of the U.S. government...It is a worthy book for almost anyone who has a computer. -Louis Kruh, Cryptologia, Volume 30, 2006 Brute Force is about as entertaining a read as you will get on cryptography. It provides a detailed account of how DES was taken down and is an interesting read for any student of cryptography and the crypto wars of the 1990s. -Ben Rothke, UnixReview.com, September 2005 Matt Curtin was right at the heart of the Deschall cracking effort, and his book is excellent in describing the day-to-day progress towards the goal... -Richard Clayton, Times Higher Education Supplement (U.K.), October 2005 "This book is an exciting popular account of an important event nearly ten years ago in the social history of cryptography. … The book is written to tell the story of how the DESCHALL (Des challenge) project came together, to encourage interest in cryptography amongst the young and to make the subject more accessible to people. It would seem to be successful on all counts." (P. D. F. Ion, Mathematical Reviews, Issue 2006 j) "DESCHALL’s goal was to search through 72 quadrillion keys to demonstrate the feasibility of a brute force attack on DES … . Curtin starts with the genesis of DES … . he manages to keep interest alive with a taut but lively prose, a focus on the human element of the story … . the non-technical reader will appreciate the evocative similes … . Perhaps most intriguing in Curtin’s narrative are … the human and social aspect of divvying up the workload … ." (Daniel Bilar, MathDL, November, 2005)
