Abstract
Cryptographical applications demand for high speed and high security. This paper describes the progress in the design and the implementation of a new powerful DES chip. The design methodology and the use of CAD tools at the different design steps is explained. The result is a single chip of 25 mm2 in 3 ¿ double metal CMOS that combines the DES algorithm with a number of unique security features. Functionality tests show that a 20 Mbit/sec datarate is achieved for all 8 bytes modes with a 16 Mhz clock.
