SD Association Announces New Security Features Share This on LinkedIn   Tweet This   Forward This

18 May 2022

SD Association has announced three advanced security features in the new SD 9 specification: Boot support, Trusted Computing Group Storage and Replay Protected Memory Block authenticated memory.

The new spec gives device manufacturers the ability to use an SD memory card for all memory and storage needs, simplifying future device upgrades or repairs and enhancing security capabilities for applications when the cards are tightly bound to specific hosts.

"SD memory cards are a compelling choice for both storage and memory because they will boot devices, are capable of delivering SSD performance levels and simplify device repairs or upgrades," said Hiroyuki Sakamoto, SDA president. "The SD 9 specification gives product manufacturers a compelling array of choices when defining memory and storage needs of devices."

The optional features defined in SD 9 are available to both microSD and full-sized SD memory card form factors. The features are applicable across all capacity types, from SD to the forthcoming SDUC memory cards. Importantly, these features will be supported by SD Express, capable of delivering SSD performance levels up to 4-GB/sec.

SD Specification 9 --New Opportunities for Sd Memory Cards as Semi-Embedded Memory

New security features let cards boot devices, securely manage memory and meet electronic right to repair regulation

SAN RAMON, Calif. -- SD Association has announced three advanced security features in the new SD 9 specification: Boot support, Trusted Computing Group Storage and Replay Protected Memory Block authenticated memory. SD 9 gives device manufacturers the ability to use an SD memory card for all memory and storage needs, simplifying future device upgrades or repairs and enhancing security capabilities for applications when the cards are tightly bound to specific hosts.

SD 9 defines Fast Boot and Secure Boot capabilities giving cards the ability to serve as a device's boot code memory while offering a simple fast boot code uploading process along with secured methods of providing future boot code updates. SD 9 adds TCG secured storage by adding self-encrypted drive functionality. The specification defines RPMB as a secured hidden memory accessible only through a secured authentication process, while also providing a secured boot code update process, plus write-protect and replay protection security mechanisms.

Devices ideally suited for the new capabilities defined by SD 9 include Chromebook computers, tablets, drones, surveillance cameras, dash cameras, gaming consoles, virtual reality headsets/glasses, small IoT modules and wearable medical devices, to name a few. SD 9 also helps product manufacturers meet new right to repair regulations and simplifies upgrade and repair processes for devices installed in locations without Internet connectivity.

"SD memory cards are a compelling choice for both storage and memory because they will boot devices, are capable of delivering SSD performance levels and simplify device repairs or upgrades," said Hiroyuki Sakamoto, SDA president. "The SD 9 specification gives product manufacturers a compelling array of choices when defining memory and storage needs of devices."
