A sensor arrangement comprises a communication device and a sensor element. The sensor element is configured to record a property and provide a sensor signal that represents the property. The sensor arrangement comprises a security element configured to provide a secret. The sensor arrangement is configured to link the sensor signal to the secret to obtain a linked sensor signal, transmit the linked sensor signal to a communication partner using the communication device, obtain a test signal from the communication partner using the communication device, and perform a check to determine whether the test signal comprises the secret.
