Multi-channel transmission method for improving TCP reliability and transmission efficiency in UNIWAY

In ubiquitous computing environment, data is collected by a number of devices and transmitted to a central server which is trusted to provide the information to the user. In order to cope with security threats targeting the central service providing system, there is a growing trend to use unidirectional data transmission gateway to completely block the possibility of intrusion of an external network and an internal network. There is a difficulty in that a physical unidirectional data transmission gateway up to now can use only a single session and does not support a private protocol. In this paper, we propose transmission control protocol based service which is a constraint in unidirectional security gateway system was being available, and unidirectional security gateway using multi-channel transmission method for transmission efficiency in multi-proxy operation and transmission control protocol’s reliability and enhance transmission efficiency of the unidirectional security gateway and shows the experimental results of proposed method.
