We want to secure the transport of MQTT-SN messages send over UDP e.g. with DTLS.
Searching the internet showed that there are considerations and activities on using DTLS to secure the transport of MQTT-SN messages over UDP but there doesn't seem to be much velocity behind them and I found no solution which seems to be ready for production.
- Are you aware about any solutions for securing the transport of MQTT-SN messages over UDP which are ready right now?
- Any ideas what else to investigate beside DTLS?
