I got a Microsoft Sculpt keyboard, as it seems to be a small improvement over the much loved Ergo 4000. (What I'd give to have an Ergo 4000 with CheryMX Blues...)
On various sites, they have this one snippet:
Proprietary 2.4 GHz with 128 bit AES encryption
Anyone knows what this actually means? Does each keyboard/receiver pair have some pre-initialized key? During sync, is there some keyexchange but after that point, it's safe?
Or is using this wireless keyboard a constant security threat? I'm aware of TEMPEST and other attacks, but this is deliberately broadcasting my keystroke data. If the 128-bit AES stuff is just some weak global key like "MicrosoftHardware" then it shouldn't be hard for someone to pick it up.
Has anyone investigated the MS wireless keyboards that explicitly claim AES?
