摘要：Protection of private keys used to digitally sign files to be downloaded to aterminal is accomplished by storing the private keys in smartcards, and arranging a
secure processor unit embedded in the smartcard to perform all signing operationsrequiring access to the keys so that the keys never leave the card. In addition, access tothe signing operations is protected by multiple PINs, which may be distributed tomultiple individuals and/or used to establish different signing authorization levelsassociated with different types of files.
