ABSTRACT:
A method, system and program are disclosed for efficiently processing host data which comprises encrypted and non-encrypted data and is to be written to a storage medium. The encrypted data is written to the storage medium in encrypted form. The non-encrypted data is encrypted by a storage device using a well known encryption key and written to the storage medium. In this way, the data that is processed by the storage device to and from the storage medium can always be processed through a single encryption engine.
