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.
