Karsten Nohl has assessed various manufacturers keyfob immobilisers and concluded that most of the older 40 &#038; 48 bit AES systems are now hackable. Last year he took 6 hours to discover the algorithm used to create the encryption key in a Hitag 2 system. Armed with that algorithm he could in theory unlock any car using NXP Semiconductors Hitag 2 system &#8211; according to New Scientist.<\/p>\n<p>Security professionals now believe a move to 128 bit immobilisers is the way forward. Both Texas Instruments &#038; NXP now offer 128 bit AES systems &#8211; which would take so long to crack that it&#8217;s not worth even trying. Apparently, the car manufacturers don&#8217;t see the urgency to switch. They point out that any car can still be removed by a thief using a flat-bed truck &#038; a GPS\/GSM radio jammer.<\/p>\n<p>We&#8217;ve written previously about crimes here in the UK, involving the theft of laptops &#038; phone from cars by thieves using jammers to stop the owners locking their car doors using the immobiliser keyfobs.
