本文介紹了安全隔離和信息交換技術，分別討論了網(wǎng)絡控制、數(shù)據(jù)加密及數(shù)據(jù)交換三個關鍵技術的實現(xiàn)原理，提出了一種新的網(wǎng)絡終端信息數(shù)據(jù)交換安全機制，詳細論述了該安全機制的設計方案。該信息數(shù)據(jù)安全交換機制采用軟硬件結合的方法，實現(xiàn)了信息數(shù)據(jù)的快速交換，保障了網(wǎng)絡終端信息數(shù)據(jù)的安全。
關鍵詞：加密、網(wǎng)絡檢測控制、數(shù)據(jù)交換、DSP

【Abstract】： This paper introduces the new technology of security isolation and information switch. After discusses three key technologies which are network control、data encrypt and data switch, This paper brings forward a new network terminal information switch mechanism, and a particular discuss about the design project. The information security switch mechanism adopts the method of hardware and software combination to realize the information switch, and ensures the security of network terminal information.
