Recently, AMI added support for the Block SID Physical Presence Interface (PPI) specification for NVMe drives running Aptio® V UEFI firmware. The Block SID PPI specification is defined in the Trusted Computing Group’s (TCG) Storage Opal Integration Guidelines, which specifically outlines the SID authority and how it manages storage devices.

Security plays a big part when it comes to technology and Block SID gives users an extra layer of security for their drives. Block SID Physical Presence elaborates on this extra layer of security by creating a way to authorize TPM-related technologies (which includes Block SID!). Physical Presence requires a platform operator to carry out platform operations initiated by the OS. That means, the platform operator has to physically be present to make sure the operations are authorized. This is beneficial for security purposes because then users can lessen the risk of unauthorized and/or malicious changes encrypting the drive. The support for the Block SID specification allows users to protect their devices from being accessed by unauthorized sources and authenticate the SID authority. For customers who want to streamline their security offerings for their customers and create secure platforms, the new support for Block SID Physical Presence puts those abilities into the hands of users.
