Method for the design of information protection systems

Problems that arise in the course of designing information protection syste ms on the basis of an integrated approach are considered. Variational probl ems of optimal choice of protection strategies in the presence of informati on constraints and constraints on the cost of the attainable systems effect are solved. Assumptions from information theory relative to the new area o f study are developed through introduction of a probabilistic penalty funct ion and by taking into account the second initial moment of a random quanti ty of information about an opponent.
