| Abstract: | The security problems of the Internet at network layer are analyzed. Two kinds of design approach of security system at network layer are proposed. One, which is based on the cur- rent IP protocol, is to establish firewalls combined with IP packet - filter routers and proxy servers. The other, which is based on the extended IP security protocols, is to establish security systems of VPNs through the Internet. Their system theories and design principles are discussed respectively. |
