Stuttgart students develop crypto chip
The eight head team "pg99" at the computer science dept of stuttgart university under guidance from Dipl-Ing Gundolf Kiefer has developed a complete crypto chip, which can do RSA (768 bit) and DES. With DES, with is intended for large data volumes, the chip can to 168 MBit/sec. The higher level RSA is being used mainly for DES key exchange, for authentication and for digital signatures. The chip will to ~50 keys/sec in RSA. Communication with the environment can be done via a parallel interface (8, 16 or 32 bit) or via two-wire I2C bis, which can be found on many current motherboards (Intel calls this SMB).
The 100,000 gate chip will be produced by Alcatel in 0.35 m technology (compare this to the 134,000 gates in an 80286). Officially the chip will be unveiled at the 8th of July at the computer science faculty, where the VHDL source of the design will be made availabe as Open Source.
