A SECURE IP ACCESS PROTOCOL FRAMEWORK AND SUPPORTING NETWORKARCHITECTURE

摘要

A protocol framework for a Secure IP Access (SIA) method, and supportin g components deployed on IP hosts and IP networks. Using this method, an IP ho st can establish a secure data channel within an IP network over an insecure shared link while requesting IP address and networking configuration parameters from the IP network. A system administrator can implement strong access control against various attacks that an edge IP network may have to face, such as a denial-of service attack that exhausts assignable IP addresses. This is a lightweight, scalable, and backward- compatible solution that can improve security performance for public and corporate LANs having open access such as wireless access points and Ethernet jacks.
