  Just imagine the TLS handshakes.

    Well, are you talking over RF, or laser communications? https://www.nasa.gov/mission_pages/tdm/lcrd/index.html https://www.nasa.gov/mission_pages/tdm/lcrd/index.html

      Both of those are limited to the speed of light in a vacuum.

    Perhaps http/3/QUIC can help? UDP and all plus 0RTT handshakes with tls 1.3. Maybe not very good for RDP or IRC. But if I am rich like elon musk I think I will just watch Netflix and regular sites like HN or reddit. Maybe have a caching proxy on high earth orbit.

      I'm not sure what work's been done on interplanetary / space-based network security, but suspect it would have to be based on known secrets or keys, cached well ahead of time. Certainly, any protocols based on handshakes would be a non-starter even at lunar distances (384,000 km, 1.28 light seconds), let alone interplanetary ones (20 minutes to Mars, up to 90 minutes to Jupiter). At interstellar ranges, the problem becomes even more complex, with keys taking years to be received. There are some preliminary discussions of space-based IP communications. I do suspect that UDP would be preferred over TCP, for obvious reasons.
