Tamper-resistant circuitry for use with an electronic device is provided, where the electronic device comprises a plurality of connections for coupling the tamper-resistant circuitry to functional circuitry for performing functionality in connection with the electronic device. The tamper-resistant circuitry comprises an interface for coupling to the plurality of connections and a power source for coupling to at least one connection in the plurality of connections. The tamper-resistant circuitry further comprises circuitry operable to evaluate a measure of an operational parameter related to the power source and in response to a signal at at least one connection in the plurality of connections, to provide an acceptable range for the operational parameter, and to inhibit standard operation of the functional circuitry in response to detecting an anomaly in the functional circuitry by detecting that the measure is outside the acceptable range. |
