SD Ver.9.00- New Optional Functions for semi-embedded Higher Security Applications
https://www.sdcard.org/cms/wp-content/uploads/2022/05/Boot-TCG-and-RPMB-The-New-Security-Featu-res-Introduced-in-SD-9.0.pdf

SD9.0 features provide enhanced features that may open new opportunities
for SD cards usually tightly bound to a specific host product as:
Semi-embedded devices replacing the soldered embedded memory (IoT, Chromebooks etc)
As a secured memory for OEM applications (ie Gaming, Automotive, VR etc)

1. Boot
 Fast Boot and Secure Boot features give cards the ability to serve as a device’s boot code memory by using asimple and easy fast boot code uploading process, along with secured methods of providing boot code updates

2. TCG Storage
 A secured storage method defined by the Trusted Computing Group adding a self-encrypted drive capability

3. Replay Protected Memory Block (RPMB) Offers a secured hidden memory accessible only through a secured authentication process and provides asecured write-protect mechanism, secured boot code update and replay protection security mechanism©SD Association.
