COMPUTER-READABLE STORAGE MEDIUMS FOR ENCRYPTING AND DECRYPTING A VIRTUAL DISC

摘要

A computer-readable storage medium (916) containing machine executable instructions that when executed by a processor cause the processor to encrypt a virtual disc; wherein the virtual disc comprises a virtual disc image; and wherein execution of the machine executable instructions cause the processor to: receive (600) the virtual disc; increase (602) the size of the virtual disc; write (604) a decryption-master- boot-record and a decryption program to the virtual disc; encrypt (606) at least a portion of the virtual disc image, wherein the decryption program comprises decryption-machine- executable-instructions for decrypting the at least partially encrypted virtual disc image in accordance with a cryptographic key (944).
