Founded in January 2000 by Panasonic, SanDisk and Toshiba, the SD Association is a group dedicated to establishing SD standards and facilitating their adoption and development. At its outset the Association represented just 14 member companies and has grown into a global alliance comprised of around 1,000 member companies. By developing and adopting SD standards, members enjoy better compatibility of member cards between devices, greatly enhancing consumer enjoyment and convenience.
Advanced Security SD (ASSD) provides an environment to communicate additional security systems on an SD memory card.
The security system can be designed for various security purposes such as data protection, DRM and monetary secure element.
An example of a security system is smartSD standard, which has a smart card element in the SD memory card.
ASSD defines security related operations such as authentication or access control to assets stored on the SD memory card. The host device can select one of the security systems and communicate through ASSD commands.
