Ouch! Encrypted communications between your computer and peripherals have to be impractically difficult to crack. The encryption scheme described in “Security firm cracks encryption for Microsoft’s wireless keyboards – heise Security” is beyond pathetic. I hope other manufacturers have more reasonable encryption schemes. In the mean time, don’t type anything on a Microsoft wireless keyboard you wouldn’t want to see published like, say, your bank account password. Disgraceful!

Nice find. It’s not that encryption where the source is kept secret is inherently insecure, it’s just that all such implementations are.
