I think so; there are some details of resale that BRSKI would like to make
out-of-scope for the first document.  Some way, we have to deal with it,
and I would actually like feedback from OPC about the parameters of different
solutions here.

    > 2) If the answer to 1) is yes then can it work with OPC UA security?

yes, I think so.
is there any open source reference code for the OPC UA security?

I think yes.
