Abstract

A circuitry is provided. The circuitry comprises a signature memory having stored thereon a plurality of stored signatures. Moreover, the circuitry comprises a signature generator configured to receive one or more monitored signals, and to generate a generated signature depending on at least one of the one or more monitored signals. Furthermore, the circuitry comprises one or more subunits configured to be accessed depending on at least one of the one or more monitored signals. Moreover, the circuitry comprises a protection unit configured to restrict access on the one or more subunits. Furthermore, the circuitry comprises a decision controller configured to compare the generated signature with a stored signature of the plurality of stored signatures to obtain a comparison result. The protection unit is configured to provide access to one of the one or more subunits depending on the comparison result.
