Louay D. Methods and means for efficiency increasing of data transfer in the protected communication environments

The dissertation is devoted to the problems of data transfers efficiency increasing in the secured communication environments on the basis of secured mechanisms, that ensuring a raised level of users data transfers along with the certain network security level. The method of early data packets transfer delay (EDPTD) for throughput increasing of links channels of the network servers, which realizing the authenticating protocols, is suggested. The mechanisms for the network congestions prevention, based on EDPTD method allow to increase networks throughput up to 10-16%. The modified authenticating protocol for the computer networks is suggested. This protocol is realized up to 18-20% faster than the base protocol version. The combination from the modified authenticating protocol and the data transfer control mechanisms in the computer networks on the basis of the early data packets transfer delay method allows to increase the efficiency of authenticating protocol realization up to 25-30% in compare to the same parameters of the base protocol version, that is especially important in the real practices.
