ABSTRACT:
A cryptographic system enables a secure, but low-bandwidth, cryptographic module, such as a smartcard or PCMCIA device, to serve as a high-bandwidth secret-key encryption decryption engine which uses the processing power of an untrusted, but fast, host processor without revealing the secret key to that host processor.
