CRISP Cryptographic Reduced Instruction Set Processor Smartcard

CRISP is funded by the European Community under ESPRIT IV. CRISP is a follow-on project of the ESPRIT III funded project SOScard. The Institute for Applied Information Processing has designed, built, and optimized the Cryptographic Logic Unit (CLU) for this project. The CLU is a full-custom scalable VLSI-macrocell design for cryptographic functions, symmetric as well as asymmetric. The CLU may be incorporated in other silicon designs and is available with a broad spectrum of interfacing options, such as OMI's PI-bus, PCMCIA, and a variety of custom interfaces. The CLU has been designed with the low power budget of smartcards in mind. But, due to the scalability of the design it easily copes with other power, speed, and area tradeoff requirements.
