FUZZY SYSTEM OF ACCESS DISTRIBUTION WITHIN A COMPUTER NETWORK

Continuous growth of volumes of information resources causes strict requirements to crypto protection on the processing speed of entrance data by the computer system. It is natural that for the solution of this task it is necessary to use hardware realization of known algorithms of cryptographic information protection. The method of the information protection transferred in computer networks by the choice of information encryption algorithm on the basis of fuzzy logic is offered in the article. The mechanism of fuzzy logic of Mamdani working on the min-max law is used for effective and fast reconfiguration of the server according to the current requirements of the system on the crypto strength, productivity and expenses of memory. The base of the fuzzy controller rules working on the classical mechanism of Mamdani consists of 63 rules. The offered method of fuzzy data processing is based on the division of fuzzy information processing in grade levels and operation that allowed to reduce quantity of output areas to 14 and accordingly to reduce number of operations to 4 times. The formed fuzzy system allows carrying out adequate data protection in real time, considering current state of the most computer system.
