FREQUENCY SENSOR FOR SIDE-CHANNEL ATTACK

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be used for detecting an incorrect clock frequency. In one example, the apparatus includes a first circuit configured to compare a clock signal period to a delay period. Additionally, in one example, the apparatus includes a second circuit configured to output a first signal. The period of the first signal may be double the clock signal period when the clock signal period is greater than the delay period. The apparatus may, in one example, also include a third circuit configured to output a second signal. The period of the second signal may be greater than double the clock signal period when the clock signal period is greater than the delay period.
