SECURE COMPUTER MEMORY CARD

摘要

A detachable PCMCIA memory card (100) incorporating a smartcard integrated circuit (250) for storing a password value and logic circuitry for preventing access to information stored on the memory card (100) unless the user of the host computer (110) to which the memory card (100) is connected can supply a password matching the stored password. The smartcard integrated circuit (250) may also be used to store public and private key values used to encrypt and decrypt data stored on the card (100) or elsewhere on the host computer (110) or exchanged with a remote computer (120).
