You're not alone in wanting secure communications for robotics.  We
would be remiss in a major rewrite to completely ignore security
(which is not to say that we must implement security mechanisms, but
we'd better at least end up with a solid story about our approach to
security, with clear guidance to users).

As I understand it, there's a proposed extension to the DDS spec,
currently under review, to add security.  Here's a relevant
presentation:

But given that DDS is apparently used in so many mission-critical
applications, surely there's some encryption happening, perhaps in
non-standard vendor-specific ways that vary by implementation?  Or
perhaps they're using DDS like we use ROS, where you're expected
secure your network.
