A Network Boundary Gap Technique Scheme Based on Dual Unilateral Path

Abstract

The traditional network boundary gap technique which can't ensure the confidentiality of information absolutely when interact the information was analyzed. This paper prompts a new technical absolution: A dual unilateral path of information interacting scheme based on unilateral transferring technique by means of partition of information flows. On one hand, this new scheme can confront the connection oriented attacks including the Trojan horse based on TCP and UDP effectively without depending on the current Trojan horse detection technology absolutely, On the other hand, the scheme can confront the data oriented attacks, that is to say, it can protect the confidentiality of the inner system data from destroying by the Trojan horse which was embedded into the inner system through other ways.
