Babenko V. The method of increase of fast-acting of the protection systems of information on the basis of the use of the specialized boolean functions

A primary purpose consists in the decision of important scientific and technical task of increase of fast-acting of the protection systems of information on the basis of the use of the specialized boolean functions of cryptographic transformation. A research object is a process of defence of information, which is saved, processed and passed in the computer systems and networks. In the process of synthesis of the specialized boolean functions the mathematical vehicle of information, scales of notation, methods of discrete mathematics theory, theory of logic, cryptography and computer design is used. The method of increase of fast-acting of cryptographic transformation of information is first developed on the basis of the specialized boolean functions, realization of which upon resulted settlements improves operativeness of treatment of information from 1,57 to 2,92 times depending on time of receipt of key sequence and bit of transformation; the formalized model of compatible device of cryptographic transformation of information which will realize the developed method of increase of fast-acting of the protection systems of information on the basis of application of sets of the specialized boolean functions is first got; the methods of synthesis and analysis of the specialized boolean functions is improved for cryptography, that enabled to extend the plural of functions and ground efficiency of their application in cryptosystems. The practical value of work consists in taking of the got scientific results a competitor to the concrete engineerings methods, algorithms, models and variants of functional diagrams of the specialized discrete devices of cryptographic transformation for the protection systems of information. A purview of the object of research are the specialized discrete devices of cryptographic transformation and specialized software of the computer systems for defence of information in the real time.
