Head Karpinskyy Mykola Petrovich, Registration Date 16-01-2009 Organization Ternopol National Economic University popup.description2 Research object is the elements and devices of the stream cipher systems with optimization on the parameters of resistance and implementation with the resistant elements to the engineering attacks of management for the calculated technique. Research goal: The purpose of research work is a decision of tasks of planning the highly productive stream ciphering devices with resistance to the side-channels attacks, intended for providing of cryptographic defence in control system and the control telecommunications and computing engineering centralized traffic. Research methods are founded on the basis of calculable mathematics theory and cryptography, theory of computer planning and big integrated circuits, modelling of algorithms and devices of the computing engineering, experimental researches. Results of researches: the methods of key gamma forming of arbitrary length are improved on the basis of management of duty and interfusion of initial sequences operations a few stream ciphers with the adaptive change of feed-backs polynomials that provides the level increase of linear complication of initial sequence and control system and computing engineering resistance according; new models and algorithms of attacks realization are developed on the basis of vehicle failures bringing on base the component of LFSR, and also on the basis of analysis of energy consumption of stream codes built on LFSR by Hemming weight; methods and charts of counteraction the attacks of vehicle failures bringing are offered and developed by partial duplication with application of detection chart of failures and forming of codes of basic registers of base component of LFSR; the new mathematical models of complication indexes, productivity and cryptographic firmness are developed for prognostication and choice of structural parameters of devices for the stream ciphering basic on the Gollman cascades; the analytical method of kvazi-optimal estimation of structural parameters of key gamma forming devices is offered for the systems of the stream ciphering based on the effective genetic algorithm.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
