Yes, CCSDS Magenta and Blue reference books mandate AES-256-GCM as a minimum for data encryption and mandate that encryption and authentication should be used, particularly for commands/uplink. Sliding scale of requirements based on application of course - your cubesat's imaging system is less critical than the flight termination system on a manned mission, for instance.

Fwiw, sat c&c is the one thing you're allowed to use encryption on the Amateur radio bands for.

  how is that enforceable? you can't determine what the encrypted communication is.

    Same as anything in amateur radio. There'll be a lot of hints at what you're doing from the shape of your broadcasts, and there's a lot of amateur radio enthusiasts that'll call the feds on you if they get a hint that you aren't following the rules.

      radio enthusiasts are fans of the fed?

        They're generally very into enforcing the FCC rules, and calling the feds is one mechanism for doing that.

Usually the 'self-policing' by hams (it's usually very effective) is done gently. They get that the frequencies are free of $$cost, and don't want to lose (any more of) them.
