|
Returns the type of authenticated channel.
Output data structure: D3D11_AUTHENTICATED_QUERY_CHANNEL_TYPE_OUTPUT |
|
Returns handles to the cryptographic session and Direct3D device that are associated with a specified decoder device.
Input data structure: D3D11_AUTHENTICATED_QUERY_CRYPTO_SESSION_INPUT Output data structure: D3D11_AUTHENTICATED_QUERY_CRYPTO_SESSION_OUTPUT |

|
Returns a handle to the device that is associated with this authenticated channel.
Output data structure: D3D11_AUTHENTICATED_QUERY_DEVICE_HANDLE_OUTPUT |
|
Returns one of the encryption types that can be used to encrypt content before it becomes accessible to the CPU or bus.
Input data structure: D3D11_AUTHENTICATED_QUERY_ACCESSIBILITY_ENCRYPTION_GUID_INPUT Output data structure: D3D11_AUTHENTICATED_QUERY_ACCESSIBILITY_ENCRYPTION_GUID_OUTPUT |
|
Returns the number of encryption types that can be used to encrypt content before it becomes accessible to the CPU or bus.
Output data structure: D3D11_AUTHENTICATED_QUERY_ACCESSIBILITY_ENCRYPTION_GUID_COUNT_OUTPUT |
|
Returns one of the output identifiers that is associated with a specified cryptographic session and Direct3D device.
Input data structure: D3D11_AUTHENTICATED_QUERY_OUTPUT_ID_INPUT Output data structure: D3D11_AUTHENTICATED_QUERY_OUTPUT_ID_OUTPUT |
|
Returns the number of output identifiers that are associated with a specified cryptographic session and Direct3D device.
Input data structure: D3D11_AUTHENTICATED_QUERY_OUTPUT_ID_COUNT_INPUT Output data structure: D3D11_AUTHENTICATED_QUERY_OUTPUT_ID_COUNT_OUTPUT |
|
Returns the current protection level for the device.
Output data structure: D3D11_AUTHENTICATED_QUERY_PROTECTION_OUTPUT |
|
Returns information about a process that is allowed to open shared resources with restricted access.
Input data structure: D3D11_AUTHENTICATED_QUERY_RESTRICTED_SHARED_RESOURCE_PROCESS_INPUT Output data structure: D3D11_AUTHENTICATED_QUERY_RESTRICTED_SHARED_RESOURCE_PROCESS_OUTPUT |
|
Returns the number of processes that are allowed to open shared resources with restricted access.
Output data structure: D3D11_AUTHENTICATED_QUERY_RESTRICTED_SHARED_RESOURCE_PROCESS_COUNT_OUTPUT |
|
Returns the number of protected shared resources that can be opened by any process with no restrictions.
Output data structure: D3D11_AUTHENTICATED_QUERY_UNRESTRICTED_PROTECTED_SHARED_RESOURCE_COUNT_OUTPUT |
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.
