Secure Communication / Encryption using v4.5.2

[charlie-norgaard]

Using COSMOS 4.5.2, what is the best way to implement encryption for communication with a satellite (from a ground station)? My team obviously doesn't want anyone else controlling our satellite from another ground station, so we just need a way to encrypt our messages to the satellite with some sort of secret key, which can be searched for and authenticated by our satellite.

I see in the system configuration document that there's support for Hashing Algorithms and X CSRF tokens. I would assume that including a X CSRF token in our configuration is the answer to my question, but I don't know exactly how it works. Is the secret token just added to the front of outgoing command packets? What sort of algorithm(s) will be necessary on the satellite end in order to decrypt and authenticate our commands?

Encryption to/from a COSMOS target would be implemented using a custom protocol.

The Hashing Algorithms and X-CSRF token stuff is for securing the API connections to COSMOS itself.
