METHOD, DEVICE AND SYSTEM FOR AUTHENTICATING ELECTRONIC ARTICLES Russian patent published in 2014 - IPC G01R31/01 

FIELD: physics.

SUBSTANCE: invention relates to electronic engineering and specifically to a method, a device and a system for authenticating electronic articles (packaged devices, blocks, modules). The method comprises transmitting an input signal with frequency in the range of f₁ to f₂ to a socket, said frequency being selected such that characteristic resonance frequencies of the internal volume of the housing $$f_i\sim \frac{c}{L_i},$$ where c is the speed of light, L_i denotes characteristic dimensions - height, width and depth of the housing of the article under analysis, are lower than f₂. Electrical characteristics of the output signal are measured and then compared with similar characteristics of a reference signal obtained using a sample from the same batch of articles with an internal structure that was investigated in detail in advance and was selected as a reference sample.

EFFECT: non-destructive authentication of a batch of devices and faster analysis.
