物理隔離網(wǎng)閘技術(shù)是一種越來越受到重視的安全技術(shù)。文章首先分析了現(xiàn)有網(wǎng)閘產(chǎn)品
實現(xiàn)的局限性，然后針對其在依賴硬件技術(shù)和只針對特定應(yīng)用的限制提出了一種改進(jìn)的安全隔離網(wǎng)閘的實現(xiàn)方法。避免了硬件技術(shù)的可用性和壽命時間的限制，提高了可擴(kuò)展性并且節(jié)約了成本。

Abstract: The technology of Physical Isolation (Air Gap) is taken increasing
importance to the network security. First this paper analyzes the limitation of the
current realization. And then it brings forward an improved implementation on the
GAP, which is based on the limitation of the current technique of the hardware and
the application. It avoids the restriction of the application and the time limit.
Furthermore it improves the expansibility and saves the cost.
