摘要（英）：

The invention discloses a wavelet coefficient based computer electromagnetic leakage signal identification method, device and storage medium. The identification method includes calculating frequency spectrum of an electromagnetic leakage signal under current monitoring; performing wavelet decomposition on the frequency spectrum of the electromagnetic leakage signal and determining parameters of wavelet coefficients of the frequency spectrum; obtaining conditional probability densities of the parameters of the wavelet coefficient corresponding to different computer hosts by using a conditionalprobability density classifier trained in advance and identifying the computer host corresponding to the electromagnetic leakage signal according to the conditional probability density. According to the invention, the computer host corresponding to the electromagnetic leakage signal can be identified automatically.
