SD Secure API
SD Secure Application Program Interface (API) is the common API for device driver of SD memory cards using our security method, CPRM. Developers may also use SD Secure API for SD adapters and in the direct slot of PCs to facilitate the access to the proctected area on and SD memory card by using this software.
- Common API for device driver of SD memory cards
- Defines Secure Channel
- Used to access protected area in SD memory cards
- Secure data encrypted by application is flowed through the secure channel
- (User Data Area in SD memory cards is accessed with OS)
- Supports the Manager Module to switch SD adapters
