  • Patent number: 9721100
    Abstract: Technologies for monitoring protected functionality of an integrated circuit device include an integrated circuit device having a protected function module. The protected function module includes a modifiable security device. When the protected function module is activated or powered up, an attribute of the modifiable security device is irreversibly modified. The integrated circuit device may be a processor, and the protected function module may be a debug module of the processor. The modifiable circuit device may be an oscillator. The frequency of the oscillator may change when the oscillator is powered due to oscillator aging. The integrated circuit device may be included in a computing device. The integrated circuit device may expose data indicative of the attribute of the modifiable security device to firmware or software of the computing device. The data may be exposed through a cryptographically signed, firmware-readable memory space. Other embodiments are described and claimed.
