unveiled preliminary specifications of three technologies that could
become the future standards for encryption of storage devices, hard
disk to the USB key. Bringing together specialists from storage such
as Seagate, Fujitsu, Hitachi, Samsung, Toshiba, Western Digital, Wave
Systems, LSI Logic and IBM, the TCG advocates of standardized
technologies, capable of high-level protection of data, while ensuring
some degree of interoperability between different solutions.
The specification Opal SSC (Class Subsystem Specification) is intended
primarily to the hard drive of our laptops. It defines several levels
of protection, one of which would, for example, prohibit any access to
the hard drive of a machine, even before the operating system starts.
Would then, for data centers, the SSC Enterprise Security
specification, combining data encryption and authentication process
strengthened.
Finally, the TCG specification presents a third, this time dedicated
to interoperability with the various protocols physical transfer
(SATA, SCSI, etc..) Or the current security technologies such as chip
TPM (Trusted Platform Module) that the already found in some laptops.
