Electronic tamper detection

摘要

An apparatus, method and package for electronic tamper detection. In one example, an apparatus, device or package for electronic tamper detection includes: a first inductor positioned at a first distance from a first conductive surface; a first oscillator generating a first frequency in dependence upon the first inductor; and a comparator setting a tamper detected status if the generated first frequency is not within an error tolerance to a pre-stored first frequency. One example of a method for fabricating an electronic tamper detection apparatus, device, or package is also provided.

1. An apparatus for electronic tamper detection, comprising:
a first inductor positioned at a first distance from a first conductive surface; a first oscillator generating a first frequency in dependence upon the first inductor; a second inductor positioned at a second distance from a second conductive surface; a second oscillator generating a second frequency in dependence upon the second inductor; and a comparator that calculates a measured relation between the first frequency and the second frequency and sets a tamper detected status when the measured relation is not within an error tolerance to a pre-stored relation; wherein a difference between the first frequency and the second frequency is greater than a mutual injection locking range.
