PROTOCOL OUT command
The SECURITY PROTOCOL OUT command is used
to send data to the logical unit. The data sent specifies one or more
operations to be performed by the logical unit. The format and function of the
operations depends on the contents of the SECURITY PROTOCOL field. Depending on
the protocol specified by the SECURITY PROTOCOL field, the application client
may use the SECURITY PROTOCOL IN command to retrieve data derived from these
operations.
