Car RFID Security System Cracked
From slashdot.org.
"The NY Times reports that the security chip in new auto keys has been cracked. A team at Johns Hopkins have found a method to extract the 30 bit crypto key that tells your car that the physical key in the ignition switch is the correct key. Texas Instruments has sold some 150 million security chips that are stored in the car key. The devices are credited with reducing car thefts of some car models by 90%. Stealing a crypto key requires standing next to the victim and broadcasting a series of challenges to the key and capturing the responses. The team claims an iPod-sized device would suffice to steal the crypto key in under a second. They advise wrapping your keys in foil when you're not using them. TI admits the team has cracked their code but denies there's any problem."

well, considering someone would have to crack your key's code, then find your car, then fashion a key that would open it and turn the ignition, I fail to see the isue. A flatbed truck is a bigger problem than fictious RFID cracking device, and I have a feeling flatbed trucks are far more available. It would be easier to get a lock set, ignition cylinder, and key-computer set from a salvage yard, steal the car with a truck, and swap ECUs than spend the time cracking an RFID key, IMHO.
