Project Details


This project has been funded by the European Community
under ESPRIT III, No. 9259, from 1994 until 1996.
The consortium exists of GIS (General Information Systems,
Cambridge UK), DigiCash (Amsterdam NL), and the IAIK
(Graz A). The main goal has been to provide up-to-date
technologies for smart cards, both, for operating systems
and for cryptography.

The results of SOScard are exploited in the follow-on
project CRISP, "Cryptographic Reduced Instruction Set
Processor Smartcard", which has started 1996. CRISP is
funded by the European Community under ESPRIT IV.

The Institute for Applied Information Processing has built
the CRYPTO ALU for this project leading to an enhanced
smart card. This task envolved a VLSI design which
incorporates highly sophisticated pipelining structures.
The main goal has been to minimize power supply and
silicon area, and to maximize
the benefit of pipelining in the crypto design. The
result is a ring-oriented pipelined ALU with integrated
carry handling for long integers. It is designed for true
single-phase dynamic logic, and overlaps registers and
processing elements in a ring-oriented structure.
