I think it's simply because of using a public channel for encrypted communication.
- ronsor 4mo agoTechnically all RF communications are "public." You have to use encryption if you want security.
- jjtheblunt 4mo agoWould point to point laser seem like it's RF and not readily snooped without detection?
- wang_li 4mo agoUnless you are in a vacuum, a laser that can reach a useful distance can be observed due to atmospheric scattering.
- jjtheblunt 4mo agotrue!
- 866-RON-0-FEZ 4mo agoYeah GPS is not the people's airwaves it is operated by the US Space Force, I suggest you read up on your history.
- moritzwarhier 4mo agoOK, I have to further narrow down my statement then: a publicly readable medium (or one-way channel). I didn't want to imply that regular people could simply inject data into what's emitted by GPS satellites. Sorry if that wasn't clear, but I am aware that GPS is operated by the US military.
- moritzwarhier 4mo agoThanks for all the replies: my phrasing was indeed bad I guess! A "public channel" is a very broad definition, and most communication channels, including those used for encrypted communication, are by design more or less "public". Situation with GPS that feels similar to "number stations" (which I only know about thanks to Boards of Canada's album "Geogaddi", tbh^^) is that encrypted messages are deliberatily broadcasted, not that the channel is in some way "public". The latter also applies to all encrypted internet traffic, I guess.
