BRUTE FORCE - MATT CURTIN KARTONIERT (TB)

In the 1960s  it became increasingly clear that more and more information was going to be
stored on computers  not on pieces of paper. With these changes in technology and the ways it
was used came a need to protect both the systems and the information. For the next ten years 
encryption systems of varying strengths were developed  but none proved to be rigorous enough.
In 1973  the NBS put out an open call for a new  stronger encryption system that would become
the new federal standard. Several years later  IBM responded with a system called Lucifer that
came to simply be known as DES (data encryption standard). The strength of an encryption system
is best measured by the attacks it is able to withstand  and because DES was the federal
standard  many tried to test its limits. (It should also be noted that a number of
cryptographers and computer scientists told the NSA that DES was not nearly strong enough and
would be easily hacked.) Rogue hackers  usually out to steal as much information as possible 
tried to break DES. A number of white hat hackers also tested the system and reported on their
successes. Still others attacked DES because they believed it had outlived its effectiveness
and was becoming increasingly vulnerable. The sum total of these efforts to use all of the
possible keys to break DES over time made for a brute force attack. In 1996  the supposedly
uncrackable DES was broken. In this captivating and intriguing book  Matt Curtin charts DES's
rise and fall and chronicles the efforts of those who were determined to master it.
