Abstract
The invention broadly contemplates a security solution for storage devices that is inexpensive and robust. The invention allows a store of system specific data to be used to release the hard disk key of full-disk encryption (FDE) drives. This system specific data is passed to the FDE drives and used to calculate the actual encryption key. This allows for safe disposal of an FDE drive containing confidential data, as the lack of available system specific decryption data makes decryption virtually impossible.
