Description
The goal of the study is to research experimentally a pseudo-noise sequence acquisition method for multicarrier communication systems of MC-DSCDMA, that allows low hardware requirements and able to operate in low quality channels. The way of achieving this lies in using a specially developed computer model of algorithm in Simulink. The achieved results have shown high efficiency of the considered acquisition method in contrast to sequential search method. The proposed algorithm can be used in multicarrier systems for acquisition of aperiodic pseudo-noise sequences in wireless public networks and in military communication networks

ERROR CHECK IN OPERATING CRYPTOGRAPHICALLY SECURE PSEUDORANDOM NUMBER GENERATORS
Description
Algorithms and constructing schemes of trusted pseudorandom number generators (PRNG) based on multivalued codes of residue number system are presented. An algorithm for numerical control of the operation of arithmetic adder Zm, differing by the introduction of various rules for performing the operation of "forming" of the overflow flag bit and the correction operation of the supervision data adjusting is developed. A scheme for local control of the adder Zm, which differs from the known by introduction of the overflow flag bit generation scheme and accounting scheme of the supervision data adjusting is constructed. End-to-end monitoring scheme of modular adder control and key storage device (KSD) for holding the crypto key with residual class code is constructed. The proposed scheme differs from the known by additional memory page, overflow flag bit generation scheme and by accounting scheme of the supervision data adjusting. The results of a comparative evaluation of the developed pattern for local and end-to-end monitoring of modular adder control with hardware redundancy are provided. Based on the results of the comparative evaluation it is expedient to use the modular control method in order to increase the reliability of the PRNG. At the same time, the developed algorithms and end-to-end monitoring schemes ensure elimination of the fracture areas in the control and expansion of fragments of the local (intermediate) PRNG control with minimal hardware and time redundancy. Application field of the developed algorithms and control schemes are digital devices with cryptographic functions

Description
The technique relates to the area of distribution of key information in cryptographic communication systems. The purpose of the work was to solve the problem of increasing the speed of distribution of key information for special bodies of federal bodies of critical facilities in the conditions of network-centric management and creating alternative options for the distribution of key information when key documents are compromised to special equipment. By applying the methodology, a solution to this problem is achieved by applying a key distribution method based on asymmetric cryptography using symmetric polynomials

MODELLING OF OPTICAL PULSE SIGNALS IN QUANTUM CRYPTOGRAPHY COMMUNICATION SYSTEMS
Description
It is necessary to know exact value of the full dispersion of waveguides, which leads to broadening and reduction of pulse amplitude for modeling laser radiation passage in quantum cryptography systems. The operation purpose was obtaining of dependences on a wavelength of various dispersion types according to the Sellmeier’ sequationand optical pulse radiation modelling in quantum communication systems. Dependences of the material, waveguide and chromatic dispersions on length of a wave according to the Sellmeier’s equation which allows to consider an optical fiber’s material are received. Distribution of a cryptographic impulse through fiber-optical communication lines of various extent is simulated
