Abstract:
This paper considers security mechanisms for authorizing and monitoring IP connections over wireline as well as wireless networks. The objective is to minimize the risk of an unauthorized user gaining access to a network and to prevent an intruder from stealing a connection from an authorized user.

A system, which we call Network Access Login/Authentication Polling (NAL/AP), has been developed for wireline networks. It is based on polling of the authorized connections.

Wireless mobile IP demands a somewhat different approach and a method, given the name Network Access Login/Authentication Polling by Challenge-Response (NAL/APCR), based on periodic challenge-response requests, is presented.
