OverviewOverview
Goal :
to ensure interoperability between IEEE based products, which
support Wi-Fi Protected Access functionality (WPA) from multiple
manufacturers, and to promote this technology within the business
and consumer markets.
The WPA protocol is defined by Wi-Fi document ‘WPA for
Specification – Version ,, April 29, 2003’ which
captures the clauses of the IEEE Draft that
define Wi-Fi Protected Access.
This version of the test plan applies to testing of
operation only. Multiband/mode products are only tested in
the mode.

WhatWhat isis WPA?WPA?
Wi-Fi Protected Access (WPA) is a response by the
WLAN industry to offer an immediate, strong
security solution
WPA is intended to be:
A software/firmware upgrade to existing APs and
NICs
Inexpensive in terms of time and cost to implement
Cross-patible
Suitable for enterprise, small sites, home
networks
Runs in enterprise mode or pre-shared key (PSK)
mode
WPA is a subset of the draftMSITM Confidentialstandard and
is expected to maintain patibilityMSI ConfidentialConfidential with

How WPA Addresses the WEP
Vulnerabilities ?
WPA wraps RC4 cipher engine in four new algorithms
Extended 48-bit IV and IV Sequencing Rules
2(48) is a large number! More than 500 trillion
Sequencing rules specify how IVs are selected and
verified
A Message Integrity Code (MIC) called Michael
Designed for deployed hardware
