基于FPGA的单向网络数据控制器的设计与实现

文章介绍了一种基于底层网络协议的分析与控制技术和网络通道硬件开关技术的单向网络数据控制器的设计与实现,它使得客户端上行至服务器的数据接受安全规则的检验,并保证下行至客户端的网络数据能够实时、完整地接受,从根本上解决了专用网络关键信息的泄露问题。项目采用自主设计电路,通过FPGA芯片完成网络数据流的处理,自身的安全性高,相比同类的软件产品处理延迟较低,接口简单灵活,能够应用于客户机、交换机前端进行控制。

Design and Realization of Unidirectional Network Data Controller Based on FPGA

This paper proposes a design and realization of unidirectional network data controller based on hardware protocol analysis and control technique and network channel hardware switch technique. It checked the data that was uploaded to the server according to certain security rules and promised the client side can receive complete and real-time data flow from the server side, which completely prevented key information in private network from being disclosed. The device used initiative circuit, processed network data flow though FPGA Chip, had a high level of security and low latency compared to similar software products, and had a flexible hardware interface so that it could be set up in front of both client and switch.
