加密网卡与以太局域网安全问题

Encryption Net Card and the Safe Problems of Ether Local Area Network

文章首先论述了为什么很多传统的解决网络安全的方法对局域网没有很大影响,然后描述了一个建设安全加密的以太局域网的办法——在连接个人计算机与网络的网络接口设备(网卡)上实施安全措施。该办法允许使用已有的网络结构,不需修改用户工作站软件,还可以提供对高层协议和数据的保护。

This paper discusses why many traditional approaches to network security are not so effective in local networks and describes a solution for building of secure encrypted Ethernet LANs-appling security measures in the network interface devices connecting individual computers to the network （network interface cards, NICs）.This architecture allows to use the existing network infrastructure, doesn＇t require to change workstations ＇software, and provides high level of protection.
