Harmony Security Protocol
The Harmony Security Protocol automates encryption management, assigning a
unique and dynamic WEP Key to each user. The Harmony Security Protocol includes
the following features:

the following features:
•
Uses 152-Bit WEP Encryption
•
Generates a unique WEP Key for each user that is valid only for the current net-

Periodically renews the user’s Harmony session and assigns a new WEP Key with-

Each Harmony device plays a role in the Harmony Security Protocol: the AP Controllers
maintain a database of user names and passwords to authenticate users; the Access
Points block all network traffic to or from a client until after the user has been
successfully authenticated by the Harmony System; and the Harmony client adapters
include a software utility that incorporates the Harmony logon prompt into the
standard Windows logon procedure.

When the Harmony Security Protocol is enabled, a user enters his or her
Harmony
User Name and Password during boot up. This information is forwarded to an Access
Point Controller which checks the
Point Controller which checks the
User Database to confirm that an entry exists for the
user, that the entry is enabled, and that the user has entered the correct password.
Once the user has been authenticated, the AP Controller generates a unique 152-bit
WEP Key, which it securely delivers to the Access Point and wireless client. In
addition, the Access Point allows network traffic to and from the wireless client once
the user has been authenticated.

The dynamic WEP Key generated by the AP Controller is valid only for the specified
user and only for the period of time specified by the
user and only for the period of time specified by the
Dynamic Key Renewal Interval,
for the duration of the user’s network session, or until the wireless client roams to
another Access Point (whichever is shortest). When the Dynamic Key Renewal Interval
expires or when a client roams, the AP Controller automatically generates a new WEP
Key for the client; this process is transparent to the end user and requires no
additional user interaction.

Note that if you enable the Harmony Security Protocol, you do not need to configure
WEP Keys (the Harmony System will generate keys for you). Also, if you have multiple
802.11a Access Points that wireless clients roam between, then you must enable the
Harmony Security Protocol on all 802.11a Access Points. An 802.11a client that is
using the Harmony Security Protocol cannot communicate with an Access Point that
does not have the Harmony Security Protocol enabled.
