DEVELOPMENT OF CONSTRUCTION PRINCIPLES AND CREATION OF PROTECTED SPEED DATA PROCESSING COMPLEX

The constuction principles have been developed, and the complex of the protected speed data processing in the computer-aided system (CAS) has been created. The methods of system analysis and discrete mathematics, theory of probability, cryptography and information technology have been used. The expert investigations in the specialized laboratories have been made. The methodology of constructing program mechanisms for information protection in the computer system have been performed. The new principle of the cryptographic information conversion has been proposed, the non-determinated codes with large number of the potential-realized cryptoalgorithm modifications have been developed. The program-oriented unit cryptoalgorithms providing the high speed of the information conversion have been drawn up. The combinatory-probabilistic model for generalized evaluation of the codes has been developed. The procedure of the computer system protection from program bookmarks has been proposed. The created program complex KOBRA has been certified by the Russia's State Technical Comission on the fourth protecion ability for computer engineering aids has been introduced on the interbranch level both for information protection circulating in CAS from unauthorized access and in the educational process at training of the specialists on the information protectionAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
