Best secure data transfer method?

Question

I am trying to set up a small network of computers where 4 child nodes feed small pieces of data into 1 parent node. I need data transfer between nodes that need to be protected (it’s safe, as in the case when packets are intercepted, it is not easy to determine their contents). Anyone have any suggestions? I looked at the HTTPS POST protocol and encrypted SOAP messages, but before I got my hands too dirty, I wanted to get an opinion from the crowd.

Answer 1

HTTP over TLS is fine. And, since there are already quite a lot of tools around it, this should be a fairly simple and productive approach.

Answer 6

You can configure ssh tunnels, which (IMHO) are better for transferring arbitrary data. Security is probably better because you can use public key cryptography to protect messages. The system does not scale very well, but if you have only 4 nodes, this should not be a problem.
