A method for secure configuration of a sensor system involves identifying a new sensor not activated within the sensor system, the new sensor including a new sensor identifier, establishing a first transmission link between the new sensor and a sensor controller, transmitting the new sensor identifier between the sensor and the sensor controller, generating a key pair for the sensor controller, the key pair including a controller public key and a controller private key, generating a key pair for the new sensor, the key pair including a sensor public key and a sensor private key, transmitting the controller public key to the new sensor and the sensor public key to the sensor controller, and generating a pairwise key within the sensor controller and the new sensor.
