If I recall correctly, there are two different electronic functions in key cars. One is the theft protection where the chip needs to authenticate when starting the engine (in Europe e.g. Ford introduced this some years ago, the keys had a red, and the car came with a fully red master key (yes, both a mechanical and cryptographical key) which allowed to teach the car to accept additional keys). The other function is the remote control to open the doors by pressing a button at the key. Does this attack compromise the theft protection only or the door opener as well? regards Hadmut --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
