Abstract
Official abstract text for this publication.
According to one aspect, a portable electronic device having a heat generating component, a thermal sensor, an energy storage device for powering the portable electronic device, a thermal element thermally coupled to the heat generating component, the energy storage device, and the thermal sensor. The thermal element is sized and shaped so that heat generated by the heat generating component flows through the thermal element towards the thermal sensor and interacts with the energy storage device. The thermal sensor is used to monitor a thermal profile for the thermal element, and the monitored thermal profile is compared with an expected thermal profile to determine if the integrity of the portable electronic device has been compromised.
