"So what is AES? It's a unique pre-programmed 128-bit encryption key which is designed to help prevent your keystrokes, which are transmitted over-the-air, from being intercepted and deciphered."

I just discovered the preceding at: <http://microsofthardwareblog.com/wireless-desktop-2000/>.

Neither the Product Guide nor the Technical Data Sheet provide details.

Is there really only a single hardwired key for the kbd/receiver pair as the text suggests?

"Timing Analysis of Keystrokes and Timing Attacks on SSH" has been around for a decade now. Did the designer(s) of the keyboard's OTA protocol take this sort of thing into account?

I can't decide whether this is snake oil or a case of having let the intern write a blog post unsupervised.
