S EAP (Extensible Authentication Protocol)
802.11b or 802.11b/g uses this protocol to perform authentication.
This is not necessarily an authentication mechanism, but is a common
framework for transporting actual authentication protocols. Intermec
provides a number of EAP protocols to choose for your network.
S TKIP (Temporal Key Integrity Protocol)
This protocol is part of the IEEE 802.11i encryption standard for wire-
less LANs., which provides per-packet key mixing, a message integrity
check and a re-keying mechanism, thus overcoming most of the weak
points of WEP. This encryption is more difficult to crack than the stan-
dard WEP. Weak points of WEP include:
S No Installation Vector (IV) reuse protection
S Weak keys
S No protection against message replay
S No detection of message tampering
S No key updates
S WEP (Wired Equivalent Privacy) encryption
With preconfigured WEP, both the client 700 Color Computer and
access point are assigned the same key, which can encrypt all data be-
tween the two devices. WEP keys also authenticate the 700 Color Com-
puter to the access point — unless the 700 Color Computer can prove
it knows the WEP key, it is not allowed onto the network.
WEP keys are only needed if they are expected by your clients. There
are two types available: 64-bit (5-character strings, 12345) (default) and
128-bit (13-character strings, 1234567890123). Enter these as either
ASCII (12345) or Hex (0x3132333435).
S WPA (Wi-Fi Protected Access)
This is an enhanced version of WEP that does not rely on a static,
shared key. It encompasses a number of security enhancements over
WEP, including improved data encryption via TKIP and 802.11b or
802.11b/g authentication with EAP.
WiFi Alliance security standard is designed to work with existing
802.11 products and to offer forward compatibility with 802.11i.
To start 802.11b or 802.11b/g communications on the 700 Color
Computer, tap Start
>
access the Profile Wizard for the 802.11b or 802.11b/g radio module.
A profile contains all the information necessary to authenticate you to the
network, such as login name, password or certificate, and protocols by
which you are authenticated.
You can have up to four profiles for different networks. For example, you
may have different login names or passwords on different networks, or you
may use a password on one network, and a certificate on another.
