Integration carried to extremes

There are some things that can be combined in a meaningful, even beneficial way – let’s say, a PC mainboard and a hard disk drive -, some that don’t make as much sense – there certainly is no obvious reason to integrate a telephone with a camera – and the other ones. Opinions on that matter may differ, as it might be the case with the integrated remote keyless entry (RKE) and tire pressure monitoring system (TPMS) that TRW has introduced a few days ago.

Secure radio signal puts off car thieves

What if it’s not only your car that starts blinking when you try to open it with the remote but some other cars surrounding it do the same? This might actually look funny as long as nobody else drove away with your vehicle. Fact is that radio transmission for remote keyless entry systems is still not particularly secure. This was quite a good motivation for the reseach scientists at the Fraunhofer Institute for Secure Information Technology (SIT) in Garching (near Munich) to do some brainstorming about a secure radio signal for central locking. In due course they developed an encryption technique which increases security without draining the key’s battery.
