We consider the method of parameter values estimation of dynamical system with noise in application to secure communication. We solve the problem of creating experimental radiophysical generator (Ressler generator) and comparison dynamics of numerical model with radiophysical experiment data. We analyse the influence of noise on the oscillator dynamics and parameter estimation error. We research the possibility of estimation of constant parameter and time-variable parameter, which can be modulated by different form signals. We determine the limits of applicability of the method to experimental generator.
