Abstract
A sensor apparatus includes a housing with a security device, a secure first computation device, a second computation device and a sensor element. The sensor apparatus detects a temperature in the housing, to activate the first computation device only when the detected temperature is in a predefined temperature range, to determine a session key by the first computation device and to store the session key in a second memory of the second computation device, to deactivate the first computation device after the session key has been stored, to determine data on the basis of a sensor signal detected using the sensor element and to encrypt and/or sign the data by the second computation device on the basis of the session key.
