A Reflective NetGAP Logic Framework Design

Adopting expert hardware to physical isolate the trusted network from the non-trusted network can prevent all kinds of attack basing on network layer and operating system layer etc. This paper comes up with network isolation system model based on reflective architecture. The reflective GAP is hardware-based and its purpose is to rapidly mirror buffers between the non-trusted memory and the trusted memory. We realize it by LVDS bus and high speed double switch technique. Its activities are achieved using store & forward of memory blocks. Its software system comprises with seven main basic modules. The Reflective GAP can keep good security and implement high real-time data transmission.
