EXISTENTIAL SEARCH PULSED EMISSION IN REGISTRATION MODE OF PHOTON FLUX WITH EXTENSION TIMEOF OBSERVATION ELEMENTS OF DECOMPOSITION
The proposed synchronization algorithm is two-pass system of quantum key distribution (QKDS) with the phase-encoded States of photons. The algorithm is implemented in single-photon mode to provide increased security of the connection entry process. The peculiarity of the algorithm is that for an equal number of accumulated pulses in two adjacent time intervals, a decision is made to receive a photon pulse in any of these intervals, if the number of accumulated pulses in it exceeds the number of detected pulses in other intervals.Laser communication systems differ from other transmission systems only in the construction of a linear path, which includes, in addition to the propagation medium, a set of technical means for the formation, transmission, distribution, conversion and processing of optical signals in a given frequency band or with a fixed bandwidth determined by the nominal number of transmission channels. According to the known algorithms [1, 2, 9, 10] in this case, both intervals became “noisy”, which caused the omission of signal pulses.
