Hi,
A few weeks ago the tinyDTLS project, currently hosted on SourceForge [1], has been proposed [2] as a new project under the Eclipse IoT umbrella. Since I think this might be interesting in the context of RIOT, I would like to make sure that you guys were aware of this proposal. You can ask to be listed as an « interested party », which is no other commitment than indicating you have a particular interest in seeing tinyDTLS become successful at Eclipse and possibly help make this happen with your contributions 
Cheers, Benjamin –
