Design and Implementation of Uni-directional GAP in Nuclear Power Plant
Abstract
With the popularity and development of the Internet, network security issues become the important theme we focused on day by day, and there are some kinds of network security products, for example, firewall, intrusion detection system and so on; Uni-directional GAP, as an important protective device of network security which was used mainly in the power industry, transports uni-directional data flow absolutely from the physical and link layer. At the same time, MRP (multi redundancy technology) and other technology ensure the system's high reliability, high fault tolerance, high safety and high stability. This article begins from the current network status of the nuclear power industry, and then introduces the development, concept and operational principle of the Uni-directional GAP device, finally this article introduces the successful application of GAP which ensure the reliable, secure and efficient exchange of real-time date and history logs in the KNS system (real-time monitor system) in nuclear power plant.
