Installing and Using the Nortel Networks Wireless LAN Mobile Adapter 2202
Preliminary Draft - Nortel Networks Confidential
Chapter 5
Configuring network security
Overview
This chapter explains how to use the Nortel Networks WLAN - Mobile Adapter
2202 Utility to configure network security. While using the Mobile Adapter 2202,
encrypting data can protect it as it is transmitted through the wireless network.
The Nortel Networks WLAN - Mobile Adapter 2202 Utility lets you use one of
the following connection profile options:
• WPA security
This option enables the use of Wi-Fi Protected Access (WPA). This option
requires network administration support. This option includes the EAP (with
dynamic WEP keys) security protocols: EAP and PEAP.
WPA is a standards-based, interoperable security enhancement that provides
data protection and access control for wireless LAN systems. It is derived
from and is forward compatible with the IEEE 802.11i standard. WPA
leverages Temporal Key Integrity Protocol (TKIP) and Michael message
integrity check (MIC) for data protection, and 802.1X for authenticated key
management.
WPA supports two mutually exclusive key management types: WPA and
WPA passphrase (also known as WPA-Pre Shared Key (PSK)). Using WPA,
clients and the authentication server authenticate to each other using an EAP
authentication method, and the client and server generate a pairwise master
key (PMK). The server generates the PMK dynamically and passes it to the
access point.
