SOScard

Project Description

This project has been funded by the European Community under the program of ESPRIT III in the period from 1994 to 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 highly sophisticated pipelining and VLSI design. The main goal has been to minimize power consumption 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.
