Abstrakt Abstract:

Network administrators typically employ di erent methods for authenticating
and authorizing the access to their networks. A
exible and scalable network
access method is needed to combat the ever increasing network ubiquity
brought on by technological advancements. The IEEE 802.1x Port-Based
Network Access is a technology that allows transparent authentication to
a network. It uses EAP-methods in order to authenticate against a server.
There are a lot of di erent EAP-methods to choose from, and they vary in
complexity and security.
This report will bring up the di erences between the most commonly
used authentication methods regarding the authentication time depending
on di erent delay and network load.
Results showed that EAP-methods that are less complex take less time
to perform authentication than their counterparts. When there is no delay,
or a very small delay, this might not matter, but when the delay is higher
complex EAP-methods take signi cantly longer time to perform the authentication
process. This is very negative considering the nature of transparent
authentication, and could lead to users becoming annoyed. A general formula
for determining how long time an EAP-authentication process will take
is presented.
