Abstract
An electromagnetic leakage red and black signal identification method based on information entropy characteristics includes: acquiring electromagnetic information leakage signals of an information device in an idle state and an information processing state respectively, and calculating information entropy of the electromagnetic leakage signals in the idle state and the information processing state; and calculating an information entropy change of the electromagnetic leakage signals caused by information processing, and determining whether an electromagnetic leak contains red signals when the device processes information according to the information entropy change, so as to give an electromagnetic leakage red and black signal identification result. The electromagnetic leakage red and black signal identification method is suitable for identifying electromagnetic leakage red and black signals of various types of information technology devices without the prior knowledge of specific device leakage signal characteristics or red signal templates, exhibiting great universality.
