Overview
The present invention provides an encryption determining method; the method is executed by a processor, and the method includes the following steps: receiving a trace; filtering noise from the trace and generating a filtered trace; converting the filtered trace by using a filter to generate a phasor signal; calculating a periodicity of the phasor signal by using a standard of deviation window for locating an encryption segment; extracting at least one encryption characteristic element from the encryption segment; and identifying the at least one encryption characteristic element by using a characteristic element determining model, and generating an encryption signal identification result, wherein the encryption signal identification result includes a location of the encryption segment and an encryption signal type corresponding to the trace. The present invention is able to automatically and efficiently locate the encryption segment, and to efficiently analyze the encryption signal type.Category
