PRINCETON, N.J. A processor that uses the triple-key data-encryption standard to provide hardware encryption and message authentication is now available in large quantities from Cognitive Designs Inc.
The CDI 2000 is the first in a family of cryptographic processors designed to be inexpensive and easy to use. It is capable of triple-key DES encryption at 88 million bits per second in any 64-bit mode of operation, the company said. A built-in 64-bit random-number generator supplies new key and initial vector values.
The low-powered CDI 2000 is aimed at network suppliers, computer peripherals and other embedded systems in a range of applications. It provides four key registers and two initial vector registers, and supports ANSI x3.106 modes of operation in 1-, 8- and 64-bit block sizes. Security and reliability features include bus parity checking and tamper detection. A built-in Monte Carlo Test command handles system diagnostics.
The processor is manufactured in CMOS and supports 5- or 3.3-V power. The clock range is 0 to 33 MHz. An activity monitor shifts the device into low-power standby mode automatically, saving additional power.
In lots of 1,000, the CDI 2000 is priced at $15 each in a 100-pin thin quad flat pack. Cognitive Designs offers several evaluation boards built around the new chip.
Another addition to the CDI family, the CDI 2050, will host the high-security Misty1 secret-key cryptographic algorithm developed by Mitsubishi Electric Corp. It is available in sample quantities.
