Abstract: This paper discusses the VPN security strategy of information protection. By using long-distance dialing and virtual private net, it constructs VPN which is composed or network information cryptography machine and IP security packet. The cryptography machine is made up of control PC based on security operating system, inside encryption card, net card and related software. IP security card is instored in client port and works on various of client operation systems.

摘要： 讨论了保护信息的ＶＰＮ安全策略，用远程拨号方式和虚拟专线方式建立了ＶＰＮ，包括网络信息保密机和ＩＰ安全包，其中保密机由基于安全操作系统的工控ＰＣ、内置加密卡、同卡及软件组成，ＩＰ安全包安装在客户端，适用于多种客户端操作系统．
