Overview
Encrypted signal segment locating device and method. The device is configured to execute the following operations. An encrypted signal template is transformed into a signal template formed by template signal points. The signal template is adjusted based on a frequency difference and a clock difference between a side channel input signal and the signal template to generate an adjusted template. The adjusted template and the side channel input signal are compared by using a sliding window to generate compared segments in the side channel input signal and similarities corresponding to the compared segments. When the similarities are higher than a threshold, one of the compared segments is selected as an encrypted signal segment, and an encrypted position is located by using the sliding window, wherein the encrypted signal segment is the compared segment having a highest similarity.Category
