Abstract

A system for performing high speed exponentiation in a secure environment. The system includes an interface for receiving encrypted data sent from a host system, a plurality of exponentiators capable of operating concurrently, an encyptor decrypting data received from a host system and encrypting data produced from the exponentiators, and logic circuitry for selecting an available and properly functioning exponentiator to perform exponentiation on the received data.
