The 4-way handshake (obtain/install PTK) is processed as follows: 

•

EAPOL-Key Message exchange (four messages)

•

Verify that a live peer holds the PMK.

•

Verify that the PMK is current.

•

Obtain a fresh PTK from the PMK.

•

Install the Pairwise encryption and integrity keys into IEEE 802.11.

•

Confirm the installation of the keys.

The Group Key Handshake (obtain/install Group Transient Key) is processed 
using an EAPOL-Key Message exchange (two messages).

Protocol 
Conformance 
Testing

When configured with WPA/RSN, IxWLAN tests the following:

•

802.1X Authentication when configured for full WPA/RSN

•

802.11i Pre-authentication when configured for full RSN

•

PMKSA catching results from a successful IEEE 802.1X authentication 
exchange between a given vSTA and Authentication Server

•

802.1X Key Management: vSTA/System Under Test 4-way handshake 
(EAPOL-Key messages), Group Key Handshake (EAPOL-Key messages)

•

TKIP or AES-CCM (CCMP): Data encryption (unicast and multicast)

•

WPA or RSN Information Element Conformity: presence in beacons, probe 
responses; correct AKM suite selector encoding and correct cipher suite 
selector encoding

Files

The IxWLAN SED and the IxWLAN SED-MR+ chassis have a 256MB “disk-
on-a-chip” flash. Excluding boot and firmware images, this allows for 225 MB of 
file system space to be used for event logging, certificate files, and scenario files.

Table 1-2

 lists the directories and files that are maintained in the IxWLAN flash 

file system.

config file

: The IxWLAN configuration file (

config

) stores information 

settings that can be defined using the CLI or the web-based user 
interface. A backup version (.bak) of this file is also maintained in the 
unlikely event that the original might become corrupted. IxWLAN 
loads from this file at power-up/initialization time. It contains basic 
configuration information.

•

ixwlan.sys:

 The 

ixwlan.sys

 file is the IxWLAN software image file.
