STORAGE_RPMB_DATA_FRAME structure (winioctl.h)
Using the information from IOCTL_STORAGE_QUERY_PROPERTY, an application can create an RPMB frame to perform one of the following actions: • Program Authentication Key • Query RPMB Write Counter • Authenticated Write • Authenticated Read • Authenticated Device Configuration Write • Authenticated Device Configuration Read
typedef struct _STORAGE_RPMB_DATA_FRAME {
BYTE Stuff[196];

BYTE OperationResult[2];
BYTE RequestOrResponseType[2];
} STORAGE_RPMB_DATA_FRAME, *PSTORAGE_RPMB_DATA_FRAME;
Stuff[196]
Reserved space.
KeyOrMAC[32]
Either the key to be programmed or the MAC authenticating this frame or series of frames.
Data[256]
The data input or output.

WriteCounter[4]
32-bit counter. Only required for writes.
Address[2]
The half-sector address to operate on.
BlockCount[2]
The count of half-sector blocks to read/write.
