AUTHORIZING REMOVABLE MEDIUM ACCESS

摘要

For authorizing removable medium access, a reassembly module retrieves a medium portion of an encryption key from a removable medium. The encryption key encrypts encrypted data stored on the removable medium and includes a plurality of portions. The reassembly module further retrieves the user portion of the encryption key assigned to a user requesting the removable medium. The reassembly module reassembles the encryption key using at least the medium portion and the user portion of the plurality of portions. The decryption module decrypts the encrypted data with the reassembled encryption key.
