It's easily breakable (as any other polynomial cipher).

Using the Diffie-Hellman key exchange algorithm, of course.

Here we have FSB: they aren't that technology-addicted, however being very professional.

Connection between hosts != communication between people.

Public (or improperly secured) WiFi is much more convenient, and properly configured GPG (RSA4096+Twofish+SHA2) would provide all necessary protection.
HD> Think about (ir)camera's,
Don't forget of high-power lasers. Pointing them to a camera will kill it in a several milliseconds.
HD> wearing GSM's, drones who follow you etc.
And all other Sci-Fi devices...
HD> So 100% security is not available ;-).
I'd be quite happy with 0.999999999 one - say, if no-one would be able to intercept my private communications in 100...200 years.
HD> There's always a (first) link.
You are welcome to take my public key ID from the tagline.
HD> In some ways that's good, to stop childporn for instance.
It is not, and can't be good for never reason. Once you justify privacy violation for anything, you justify it for everything.
HD> If some one wants to cath you, they will succeed ones.
So I'd like them not to want catching me.
HD> Not at every price, but some have money enough for that purpose.
For what reason?
HD> That's why terrorism is so hard to stop. 12 people died in Paris ;-(
Terrorism has nothing common with privacy (except letters "i" and "r", of course). If you want to stop terrorism, you'd better begin with stopping religious sects and reducing the tolerance.
