A few years ago I worked for a satellite imagery company. I can tell you that communications with space vehicles in orbit are heavily encrypted using very strong and very proprietary algorithms that require special hardware. Because of this encryption, I had to acquire a government security clearance.

"very proprietary" does not usually imply "very strong".

It does when "very proprietary hardware" is code for "supplied by the NSA."
