To date, many commercial applications in telecommunications, data transmission and data storage require a high level of cryptographical protection. The ASIC processor, presented here, can be programmed to execute a large set of cryptographical functions, not found in other cryptographical devices. Novel architectures for both data path and controller have been designed to realize this high degree of programmability, while still reaching a high throughput. The compact processor counts 18 K transistors on 25 mm/sup 2/ in a 2.4 mu m CMOS process and yet it reaches a throughput of 30 Mbit/s for every single-encryption mode. It is the fastest data encryption standard (DES) processor currently available.>
