FIELD: physics, computer engineering.
SUBSTANCE: invention relates to sensor devices. The sensor device is capable of determining temperature in a housing, driving a computing device only when the determined temperature lies in a given range, determining a session key with the first computing device and storing the session key in a second storage device of a second computing device, ceasing use of the first computing device after storing the session key in the second storage device of the second computing device, determining data depending on a sensor signal and encrypting or providing a digital data signature with the second computing device depending on the session key.
EFFECT: low probability of unauthorised access; the device has a housing with a security device, a secure first computing device, a second computing device and a sensor element.
