Content
Data may be encrypted and then stored on a storage device 150 where encryption is accomplished using an encryption key received by the storage device 150 in conjunction with storing the data. Where the existing data is encrypted with this received encryption key before being stored, in another embodiment the token directive generation module 1002 generates an encryption erase command along with generating a token directive in response to receiving a request to overwrite the existing data. The encryption erase command erases the encryption key used to store the existing data so that the encryption key is non-recoverable.
