TIRE PRESSURE MONITORING SYSTEM SENSOR AUTHENTICATION

Methods, apparatus, systems, and computer program products for tire pressure monitoring system (TPMS) sensor authentication are disclosed. In a particular embodiment, an electronic control unit (ECU) of a vehicle receives a first radio frequency (RF) transmission that includes TPMS data and a first signature value. In this particular embodiment, the ECU uses a key value to generate a second signature value and determines whether the second signature value corresponds with the first signature value. In this example embodiment, the ECU uses a determination of whether the second signature value corresponds with the first signature value to determine whether the first RF transmission is from a particular TPMS sensor authenticated to the key value.
