Best secure data transmission method?

Question

I'm attempting to set up a small network of computers where 4 child nodes feed small snippets of data into 1 parent node. I need the data transmission between the nodes to be secure (secure as in, if the packets are intercepted it is not easy to determine their contents). Does anyone have suggestions? I looked into HTTPS POST and encrypting SOAP messages, but before I got my hands too dirty I wanted to get opinions from the crowd.

Answer 1

HTTP over TLS is fine. And, since there is already quite a bit of tooling around it, it should be quite an easy and productive approach.
