: :
: 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. :
