Trocha historie - doba, kdy DES skon?il.
22.04.2005March 22, 1999 (Robert Moskowitz):
The summer of 1998 will be remembered as the end of an era. The EFF (Electronic Frontier Foundation) funded Deep Crack, a relatively inexpensive parallel-processing computer designed to attack cryptographic algorithms, most notably DES (Data Encryption Standard). Deep Crack solved the RSA DES Challenge II in 56 hours. John Gilmore of the EFF stated, "This would put truth into the crypto debate." At the time, U.S. government officials deprecated the event, claiming that spending more than two days to solve one file is not very efficient for a meaningful attack on DES. By the fall, the U.S. export rules were changed from 40-bit to 56-bit. This all raises three questions: Should DES still be used? If so, for what? And if not, what should replace it?
