Abstract
Disclosed are methods and systems that include receiving updated operating system information, encrypting the updated operating system information, and updating a map file. The updated operating system information is received at an encryption virtual machine. The encrypting the updated operating system information results in the encrypted updated operating system information. The encrypting the updated operating system information is managed by the encryption virtual machine. The updated operating system information is encrypted in response to receipt of the updated operating system information. The updated operating system information is encrypted using an encryption key. In certain embodiments, the updating includes storing operating system metadata in the map file (where the operating system metadata is associated with the encrypted updated operating system information) and storing the encryption key in the map file (where the storing the encryption key in the map file associates the encryption key with the operating system metadata).
