Abstract

A detachable PCMCIA memory card incorporating a smartcard integrated circuit for storing a password value and logic circuitry for preventing access to information stored on the memory card unless the user of the host computer to which the memory card is connected can supply a password matching the stored password. The smartcard integrated circuit may also be used to store public and private key values used to encrypt and decrypt data stored on the card or elsewhere on the host computer or exchanged with a remote computer.
