-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The Logitech uses a 10bit ID that is assigned to the base station/mouse/keyboard at the factory. I don't believe there is any type of encryption. I would not recommend the Logitech, they don't have very good range. I have had much better luck with the Intel version. The Intel has a much better range, plus they have a wireless gamepad option. As for sniffing thier signal, I think it would be quite easy to do to either one. Here is the frequency range, all you need is a scanner.
