Volkswagen keys are insecure, but so are everyone else’s

Earlier this week, it was revealed that researchers at the University of Birmingham had cracked the (rather poor) encryption scheme used by millions of Volkswagens for their remote unlock key fobs. That’s not good. But what’s also not good is that it’s not really new, and that it’s not limited to VW.
In the VW attack, the researchers were able to extract a cryptographic key that is one of four shared across tens of millions of Volkswagen cars. Then, they were able to eave
