Adam,
There are by my count five separate projects working on this; the most
promising is Lourens Naudé's TLS transport inside the library; the
most usable today is Salt Stack's distributed security model, which
should be quite easy to reimplement.
I'd suggest reading this:

Is there a standard approach to ensuring data integrity and security using
ZeroMQ? I'm new to this community and don't see an obvious approach.
By 'data integrity' I mean that the message recieved is the same as the one
sent. We'll mostly be messaging over TCP, which has problems with jumbo
packet
