Abstract
Systems and methods for implementing two-way tire pressure monitoring system (TPMS) learning and authenticated pairing. A random value may be used to determine a test value and a pairing PIN by use of a HMAC (Hash-based Message Authentication Code) function and a pre-shared key that is accessible to a TPMS sensor and a vehicle (e.g., controller system thereof). The random value and test value may be broadcasted by the TPMS sensor and received by the vehicle. The vehicle may calculate the pairing PIN using the random value and the pre-shared key.
