You might want to take a look at Secure Spread
Secure Spread is a research project. It provides confidentiality
on top of Spread using key management techniques to achieve
a shared key in a group. The implementation uses OpenSSL.
However, this approach does not protect  the control messages
exchanged by the server, it protects only  client data.
