Abstract:
Securing encrypted virtual hard disks may include a variety of processes. In one example, a virtual hard disk is created for a user and encrypted with a volume key, and the volume key placed in an administrator header. The administrator header may be encrypted with a protection key, the protection key created from a user identifier corresponding to the user, a volume identifier corresponding to the virtual hard disk, and two cryptographic secrets. The protection key may then destroyed after encrypting the administrator header and therefore, might never leave the encryption engine. The two cryptographic secrets may be stored in separate storage locations, one accessible to the user and the other accessible to administrators. Accordingly, the protection key might never transmitted or can be intercepted, and no single entity may be compromised to gain access to all of the information needed to recreate the protection key.
