Encrypted connections with network devices are mentioned in general,
primarily in Section 4.4, as a possibility that may be tested:
https://tools.ietf.org/html/draft-ietf-bmwg-sdn-controller-benchmark-meth-07#section-4.4

It will help if we can iterate on text to satisfy your comment,
such as adding:
4.4. Connection Setup

   There may be controller implementations that support unencrypted and
   encrypted network connections with Network Devices. Further, the
   controller may have backward compatibility with Network Devices
   running older versions of southbound protocols. It may be useful to
   measure the controller performance with one or more applicable
   connection setup methods defined below.
ADD
For cases with encrypted communications between the controller and the 
switch, key management and key exchange MUST take place before
any performance or benchmark measurements.

just trying to clarify what you want to see added,
Al
