A method for encrypting data on a disk drive using self encrypting drive is provided. The method includes encryption of data chunks of a computing device. The method further includes associating the encrypted data chunks with encryption key indexes of the computing device. Moreover, the method further includes receiving the encryption key indexes for given logical block addresses of the data chunks. The method further includes determining the encryption keys to be used to encrypt the data chunks based on the encryption key indexes of the data chunks to the disk drive.

Multiple volume encryption of storage devices using self encrypting drive (SED)

A device with mass storage capability that uses a readily available non secure memory for the mass storage but has firmware (and hardware) that provides security against unauthorized copying of data. This is true even though the firmware itself is stored in the non secure mass storage memory, and therefore potentially vulnerable to hacking. An indication of the authenticity of the firmware must be present before it will be executed by the device. This protects the device contents from unauthorized duplication or tampering. Additional functionality can be added to the device with additional firmware applications, and the authenticity of those additional applications will also be verified before they will be executed. This further prevents unauthorized copying or tampering of secure content through any mechanisms that may be unscrupulously introduced. Any data within the mass storage memory may also be encrypted.
