[quote="ruffsl, post:5, topic:861, full:true"] [quote="adnirb, post:2, topic:861"] Do you assume a one-to-one synchronous TLS communication between the nodes using topics for communication (similar to ROS services)? [/quote] Well because TLS is sort of a stateful connection, there is a handshaking process, this requires the use of TCP. So essentially all topic, service and parameter level API call in SROS currently use TLS/TCP for the network layer. I am not fully aware of the best methods to do this for UDP based connections, but perhaps someone else might want to interject here about that. [/quote] For securing UDP connections, something like [DTLS](https://en.wikipedia.org/wiki/Datagram_Transport_Layer_Security) could be used. @ruffsl: you might be interested in the [(Application-level) Security for ROS-based Applications](https://static1.squarespace.com/static/51df34b1e4b08840dcfd2841/t/582442a820099e166efe93ac/1478771378877/ROS-I-Conf2016-day2-03-dieber.pdf) presentation by Bernhard Dieber (Joanneum Research) from the last ROS-Industrial Conference (similar security considerations, but also addressing the `roscpp` side). --- [Visit Topic](http://discourse.ros.org/t/developing-with-sros/861/8) or reply to this email to respond.
