D3D11_AUTHENTICATED_CONFIGURE_INPUT structure

Contains input data for the ID3D11VideoContext::ConfigureAuthenticatedChannel method.

Syntax

typedef struct D3D11_AUTHENTICATED_CONFIGURE_INPUT {
  D3D11_OMAC omac;
  GUID       ConfigureType;
  HANDLE     hChannel;
  UINT       SequenceNumber;
} D3D11_AUTHENTICATED_CONFIGURE_INPUT;

Members

omac

A D3D11_OMAC structure that contains a Message Authentication Code (MAC) of the data. The driver uses AES-based one-key CBC MAC (OMAC) to calculate this value for the block of data that appears after this structure member.

ConfigureType

A GUID that specifies the command. The following GUIDs are defined.

Value	Meaning
D3D11_AUTHENTICATED_CONFIGURE_CRYPTO_SESSION	Associates a cryptographic session with a decoder device and a Direct3D device. Input data: D3D11_AUTHENTICATED_CONFIGURE_CRYPTO_SESSION_INPUT
D3D11_AUTHENTICATED_CONFIGURE_ENCRYPTION_WHEN_ACCESSIBLE	Sets the level of encryption that is performed before protected content becomes accessible to the CPU or bus. Input data: D3D11_AUTHENTICATED_CONFIGURE_ACCESSIBLE_ENCRYPTION_INPUT
D3D11_AUTHENTICATED_CONFIGURE_INITIALIZE	Initializes the authenticated channel. Input data: D3D11_AUTHENTICATED_CONFIGURE_INITIALIZE_INPUT
D3D11_AUTHENTICATED_CONFIGURE_PROTECTION	Enables or disables protection for the device. Input data: D3D11_AUTHENTICATED_CONFIGURE_PROTECTION_INPUT
D3D11_AUTHENTICATED_CONFIGURE_SHARED_RESOURCE	Enables a process to open a shared resource, or disables a process from opening shared resources. Input data: D3D11_AUTHENTICATED_CONFIGURE_SHARED_RESOURCE_INPUT

 

hChannel

A handle to the authenticated channel. To get the handle, call the ID3D11AuthenticatedChannel::GetChannelHandle method.

SequenceNumber

The query sequence number. At the start of the session, generate a cryptographically secure 32-bit random number to use as the starting sequence number. For each query, increment the sequence number by 1.
