If you have proper security on a higher abstraction layer you don't care at all how the data gets transmitted, who can listen to it or modify it.

  Note that on the Amateur frequencies, it's illegal to "Obfuscate" your transmissions. You can't even use coded language.

    Didn't know that. Surely some people tried steganography? Or is there too much noise to try something like that? (and thanks for the antenna book recommendation)

      That would count as "obfuscation".
      • comboy 10y ago
        It's really hard to prove steganography if you are hiding encrypted data (which looks like noise if it's properly encrypted)

  Depends on what you're trying to protect. Seeing encrypted traffic flows at Tor entry and exit nodes for example can expose identity. Being able to monitor encrypted traffic on the wire or air can yield other useful and potentially compromising metadata.
