the keyboard uses AES encryption.

[is the Microsoft Sculpt Ergonomic keyboard safe from KeySweeper?]

Great question. I have read up a little bit more and here are some relevant links:

From https://publicintelligence.net/fbi-keysweeper/ (A bulletin from FBI about Keysweeper): “A keyboard using AES encryption makes it more difficult to read keystrokes as there are currently no known practical attacks to read AES encrypted data.”

From https://www.microsoft.com/accessories/en-us/products/keyboards/sculpt-ergonomic-desktop/l5v-00001#specsColumns-testCarousel (Sculpt Keyboard specification page) : "This keyboard features Advanced Encryption Standard (AES*) technology"

And what you actually asked, the link to the claim by Microsoft. I could not find the original statement, but it's included in multiple articles on Keysweeper, so here's one; from

http://arstechnica.com/security/2015/01/meet-keysweeper-the-10-usb-charger-that-steals-ms-keyboard-strokes/

: “Update: Microsoft has issued the following statement: Keyboards from multiple manufacturers are affected by this device. Where Microsoft keyboards are concerned, customers using our Bluetooth-enabled keyboards are protected from this type of attack. In addition, users of our 2.4GHz wireless keyboard designs from July 2011 onwards are also protected because these keyboards use Advance Encryption Standard (AES) technology.”
