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.
