Sends the host certificate to the logical unit.

Major code

IRP_MJ_DEVICE_CONTROL

Input buffer

The buffer at Irp->AssociatedIrp.SystemBuffer contains host certificate of type AACS_SEND_CERTIFICATE.

Parameters.DeviceIoControl.InputBufferLength in the I/O stack location indicates the size, in bytes, of the buffer, which must be >= sizeof(AACS_SEND_CERTIFICATE).

Input buffer length

Parameters.DeviceIoControl.InputBufferLength in the I/O stack location indicates the size, in bytes, of the buffer, which must be >= sizeof(AACS_SEND_CERTIFICATE).

Output buffer

None.

Output buffer length

None.

Status block

The Information field is set to the number of bytes transferred. The Status field is set to STATUS_SUCCESS or possibly STATUS_INSUFFICIENT_RESOURCES.

Remarks

The IOCTL_AACS_SEND_CERTIFICATE request corresponds to the step in the Advanced Access Content System (AACS) authentication algorithm (AACS-Auth) in which the host sends its certificate and nonce to the drive. For a complete description of AACS-Auth, see the Advanced Access Content System, Introduction and Common Cryptographic Elements specification that is published by Advanced Access Content System Licensing Administrator (AACS LA).
