....not employ this approach in our design, as modern FPGA synthesizing tools optimize the low level logic themselves. The data rate of the implementation was not mentioned. 2.2 Current Implementations Modern custom hardware implementations can achieve data rates of 1 Gbit sec and beyond. Reference [2] was the first report of a custom chip, employing modern Gallium Arsenide technology to achieve 1 Gbit sec. In a later publication of the same research group [5] they describe this design in more detail. They also mention that the fasted chip they tested could run at 1.4 Gbit sec. One major ....

.... could break DES in 9 days with technology forecasted to be available by 1995 [18] Another more recent estimate took advantage of an extremely fast DES chip (designed for normal cryptographic use, not cryptanalysis) concluding that a 1 million assembly could search the DES key space in 8 days [31, 13, 14]. Yet another study examined the feasibility of using existing general purpose content addressable processors, and concluded that a DES keysearch would take 30 days on them with a 1 million investment [30] Even more writing on the subject of hardware DES keysearch can be found in [25] and some ....

....in 1.2 days, each DESB chip can test 5333 million keys per second. This number appears to be very high. The estimated cost including overhead is only 2500 which appears to be very low to us. Modern custom hardware implementations of DES can achieve data rates of 1 Gbit sec and beyond. References [4, 3] were the first report of a custom chip employing modern GaAs technology to achieve 1 Gbit sec. This design as well as many commercially available devices do not support a key change at full speed; i.e. a different key for every block of plain text. The first paper to show an implementation of ....
