Tire Pressure Sensor Surveillance - A Re-Tread

Researchers from Rutgers University and University of South Carolina have found that wireless communications between new cars and their tires can be intercepted or even forged...

The researchers will present their findings at the Usenix Security Symposium, being held this week in Washington D.C.

 The tire pressure monitoring systems (TPMS) consist of battery-powered radio frequency identification (RFID) tags on each tire, which can respond with the air pressure readings of the tire when wirelessly queried by an electronic control unit (ECU).

The researchers had found that each sensor has a unique 32-bit ID and that communication between the tag and the control unit was unencrypted, meaning it could be intercepted by third parties from as far away as forty meters. (more)
