Abstract The research is to assess the probabilistic characteristics of quantum key distribution system (QKDS) in synchronization mode. Synchronization methods of optical systems are described. Algorithm of photon pulse search with ideal photon counting system are proposed. PC program for imitation of first stage QKDS synchronization search algorithm is developed. Expressions for calculation of the probability characteristics QKDS on the first stage searching using photon pulses to enhance security from eavesdropping are obtained. The influence of the photon pulse parameters, the single-photon detector and equipment search with ideal photoelectrons counter by the properly probability are evaluated. Expressions for calculation a limit probability of wrong signal detection. A method for designing QKDS in synchronization mode are proposed.
