DTLS support #160

Open anandbhaskaran opened 5 years ago

anandbhaskaran commented 5 years ago

Hello. Thanks for this tool. It is really helpful.

Do you plan to implement encryption support (perhaps DTLS)? This would be a really nice addon to this tool and could transport messages more securely.

Thanks in advance.

For IP it's a solved problem: make the transport use encryption.

Over radio, you need support on the flight stack side.

Thanks for the quick response. Can you please point me to the documents or libraries to make the transport layer of Mavlink router to use encryption.

Should I extend the library with DTLS libraries like (Python DTLS) or is there any readymade solution that can forward the UDP mavlink over DTLS?

Thanks in advance.

Can you clarify what you are trying to accomplish? Where are you routing the mavlink to/from? Is mavlink-router on the drone/ground/cloud?

anandbhaskaran commented 5 years ago

I am trying to use mavlink-router on the companion computer of the drone, that has connectivity to a remote server on the network. My goal is to make this communication as secure as possible.

I would agree with Lucas, that it's not part of the scope of mavlink-router to ensure transport-layer security. If you want to have a secured link, you should rather think about adding a VPN between your companion computer and server then. But you have to search by yourself, which VPN protocol is suitable for your application.
