METHOD FOR OPERATING A SENSOR APPARATUS AND SENSOR APPARATUS

摘要

A sensor apparatus comprises a housing (G) with a security device (SE), a secure first computation device (SC), a second computation device (AC) and at least one sensor element (SENS). The sensor apparatus is designed to detect a temperature (T) in the housing (G), to activate the first computation device (SC) only when the detected temperature (T) is in a predefined temperature range, to determine a session key (SS) by means of the first computation device (SC) and to store the session key (SS) in a second memory (DMEM) of the second computation device (AC), to deactivate the first computation device (SC) after the session key (SS) has been stored, to determine data on the basis of a sensor signal (SIG) detected using the at least one sensor element (SENS) and to encrypt and/or sign the data by means the second computation device (AC) on the basis of the session key (SS).
