    摘要: An access control/crypto system having a smart card reader and an access control program for requesting information from a user to determine if the user is authorized to access the computer. The access control/crypto system uses encryption and smart card technology as a means for securing files stored on the system, telecommunicated globally, or archived to a chosen media. The system includes an access hierarchy, combined with the issuance of smart cards, to control the various levels of access provided by the system. Further, the present system provides secure file transfer by encrypting sensitive files at a first site, transferring the encrypted version to a second site, providing an authorized user at the second site with a secret password, and decrypting the file at the second site using the secret password under control of the authorized user.
