TTrusted Computing Group - Opal Storage Specification

 

TCG Opal is the storage device safety standard established by Trusted Computing Group (TCG), an international non-government organization (NGO) that develops and establishes industrial computing standards. To be TCG Opal compliant, an SSD would have the following characteristics:

 

  • Both encryption and decryption are automatically executed within the device without being processed by the Host end, while the key is stored in the device with AES-128 or AES-256 advanced encryption standard.
  • 2. Prior to power up, authentication is carried out. The user is required to enter a Shadow MBR to perform identity confirmation, and once passed, the actual power-up procedure is initiated.

  • Zoning and Authorization Setting functions where the manager can establish a Logical Block Address (LBA) to set different access limit for a different LBA, as those with the corresponding keys is authorized to enter the designated Block to execute authorized operations.
