This approach provides the ability to remotely automatic authentication in real time. The authentication template was calculated from the sequence of values of the auto-correlation function of the internal electrical noise. It was demonstrated that the noise instability of noise leads to the error in the computer authentication. In order to reduce the error's probability, it was proposed to use the form-factor of autocorrelation function histogram for automatic sorting of noise files. The character of the noise instability had allowed the use of several authentication templates for one computer with instable noise. Each template was designed for the separate stability area. The probability of false authentication was reduced by using two authentication templates for one computer with instable noise, it was 30%. The recommendations were made about determining the priority of access to confidential information for computer with instable noise.</p> ER -
