Abstract:
Hardware encrypting storage devices can provide for hardware encryption of data being written to the storage media of such storage devices, and hardware decryption of data being read from that storage media. To utilize existing key management resources, which can be more flexible and accommodating, mechanisms for storing keys protected by the existing resources, but not the hardware encryption of the storage device, can be developed. Dedicated partitions that do not have corresponding encryption bands can be utilized to store keys in a non-hardware-encrypted manner. Likewise, partitions can be defined larger than their associated encryption bands, leaving room near the beginning and end for non-hardware encrypted storage. Or a separate bit can be used to individually specify which data should be hardware encrypted. Additionally automated processes can maintain synchronization between a partition table of the computing device and a band table of the hardware encrypting storage device.
