| 摘要: |
| 针对电力系统中一些内部网络需要和Internet隔离，将会给电力系统和Internet之间的数据交换带来困难，提出了隔离网络数据安全交换系统。该系统能够有效实现2个隔离计算机网络间信息的自动安全交换。系统由应用服务器、传输代理机、控制机以及配套的隔离开关盒构成。在信息的传递过程中，对传输的数据报进行了监控，加入格式转换、原始套接字、访问控制等多项技术，确保传输过程中的安全可靠。 |

| Abstract: |
| Some internal networks in electric power system should be isolated from Internet,and it brings difficulty to data exchange.A secure data exchange system is put forth for it.The system consists of application server,agent server,controller,and switch box,which can effectively realize the secure data exchange between two isolated networks.To ensure the secure data transmission,the datagrams are monitored by applying format conversion,raw sockets and accessing control. |
| Key words: isolated networks,transmission control,raw socket,circuit interlock, |
