BMW code hopping being replicated in gauteng.

Seems that they are reading your codes and then unlocking your car when you are gone.

You guys are obviously not developers. They would need the key-gen seed which will be unique to get this right. A seed is used to calculate your next number / signal, like those security pin code generaters they use for online-banking.

Very secure system - impossible to hack on the street unless your towing a CRAY2 supercomputer around with you and you would need to sniff a couple of hundred thousand transmits to reverse engineer.

EDIT: Unless of course your referring to the old BMWs that even a paperclip could start the ignition.
 
err.. i am a developer.

anyway, saw the results... and the cops confirmed it
 
I've heard that this has been done to other cars in the past.

Bullsh1t... the code has vulnerabilities, and can be broken using sliding attacks.
I am a developer using this technology, it is known as KEELOQ, and was broken last year by the Russians. We are in possession of a paper written by a Russian mathematician that explains how to break it using the sliding attack method.

Knowing the seed helps nothing. It is the unique MANUFACTUER's KEY that needs to be determined. Once you have that cracked, it becomes a piece of old takkie to hack and to generate a cloned transmission, which by the way will then update the synch counter in the receiver, making all the legitimate transmitters useless.

That is all I am prepared to say...

Oh and FYI, this encryption is a South African invention... bought out by Microchip Technology Inc back in 1994...

well i guess BMW's MANUFACTUER's KEY is public knowledge by now
 
Does this hold true for the security gate code hopping remote system (ie Nova from Centurion) as well?
 
Oh you mean the normal remote controlled gates? They have binary codes (12-bits) and are pretty easy to crack...
 
OMG. Geeks, geeks everywhere!!!

Wish I understood half the stuff you lot have just said so i can sound clever to my friends this weekend, "hey boet, that BM of yours. Nooit, it's not as clever as I am. The binary...." :p
