The invention discloses a computer cable electromagnetic leakage characteristic
analysis method. The method comprises the following steps of identifying a leakage source, judging whether
information leakage exists or not and analyzing leakage information content; under the condition that the
electromagnetic signal characteristics are unknown, the
electromagnetic signal can be analyzed, the leakage source of the
electromagnetic signal and the leakage information hidden in the leakage source are gradually identified, the layered detection strategy of the electromagnetic
information leakage is realized under the unified
algorithm and technical framework, and the detection accuracy is improved. Compared with a traditional method for analyzing electromagnetic leakage information through operation experience and priori knowledge, the electromagnetic leakage
information analysis efficiency is improved, under the condition that the
signal-to-
noise ratio is low, features in signals can be accurately extracted to judge a leakage source, the speed of solving the optimal value through
gradient descent in the model is higher by adding a batch
standardization layer, and the method has the advantages of being high in accuracy and high in reliability. And meanwhile, the
overfitting problem is more effectively avoided, and the integrated learning method is adopted, so that the electromagnetic leakage information detection efficiency and accuracy can be relatively high under the condition of small samples.
