SICURE-a crypto chip for rapid encipherment

Abstract

The crypto chip SICURE (Siemens coprocessor unit for rapid encipherment) is a cryptographic coprocessor designed for the protection of sensitive data. The implemented DES (data encryption standard) and other proprietary symmetric block ciphers achieve confidentiality and integrity of messages. A data flow rate of more than 20 Mb/s makes it well-suited for local area networks or hard disk controller applications.<>
