A new approach to the development and evaluation of quantitative characteristics of internal electrical noise has been developed; in particular, the methodological principles of building authentication characteristics based on noise measurements have been developed. A new authenticator of electronic devices has been developed - a bit template formed from sequences of discrete values of the normalized autocorrelation function of internal electrical noise. The authentication results are superior to known counterparts in terms of accuracy and simplified configuration. A system of dynamic online authentication based on autocorrelation of internal electrical noises has been developed. The system is implemented in a hardware and software complex. A software module for self-identification of an electronic device has been developed and tested. An experimental study of the resistance of the bit template to various disturbing factors was carried out and its high stability was demonstrated. It was investigated that the operation of household appliances and office equipment do not affect the template within the authentication thresholds. Factors that significantly affect templates are intense electromagnetic radiation in the immediate vicinity of airports and TV towers, pre-thunderstorm weather. It has been experimentally shown that the influence of the "aging" factor of electronic devices components leads to a slow change in the averaged bit templates, which requires their recalculation over time. It was established that the approach using internal noise provides a significant reduction in the influence of the external electromagnetic background on noise measurements, which makes it possible to increase the probability of correct authentication to 98.6%.
