Embodiment Construction
[0038] The present invention completes security isolation and information exchange between different security domains by deploying two one-way isolation devices between two security domains, and at the same time prevents attack tools based on the TCP / IP protocol from working normally; The application layer of the gate joins the control mechanism, introduces the identity trusted authentication module of the information source, and establishes the trusted transmission of information between security domains. The one-way isolation gatekeeper realizes the access control function of network layer and application layer. The border access control model based on double-unidirectional isolation gatekeepers not only realizes the security isolation between the trusted security domain and the untrusted security domain, but also realizes the information exchange between the trusted security domain and the untrusted security domain.
