摘要: 目前网络安全措施大部分是为了防范网络外部的攻击,而对局域网内部的安全性不够重视。为了提高局域网内部数据传输的安全性,基于SOPC,采用DES加密算法和自定义局域网协议等关键技术,该文设计并实现了安全网络适配器。测试结果表明,该设计方便快捷、可重构性强,在实际局域网环境中运行性能良好。

Abstract: Most of the LAN security measures concern how to prevent attacks of outer network, while less attention is paid to the security of inner local network. To enhance the security of inner local network’s data transmission, security network adapter based on SOPC technology is designed and also implemented. In the design, the DES algorithm and LAN protocol self-define which are the key technology to enhance the security of data transmission are used. The test result shows that the adapter is convenient, effective and easy to reuse, and it also works well in real LAN environment.

Key words: security network adapter, SOPC technology, protocol self-definition
