S TKIP (Temporal K ey 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 fixing the flaws of WEP.
This protocol provides stronger encryption than WEP, by dynamically
updating the encryption keys every 10,000 packets. It eliminates attacks
on WEP, which is based on a cryptographic algorithm called RC4, leav-
ing WLANs open to various security attacks.
TKIP is an interim addition to WEP that addresses some security con-
cerns. It provides per-packet key mixing, a MIC (Message Integrity
Check), and a rekeying mechanism designed to fix WEP f laws.
S WEP (Wir ed Equivalent Privacy) encryption
With preconfigured WEP, both the client 700 Series 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 Series Com-
puter to the access point — unless the 700 Series 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-ch aracter strings, 12345) (default) and
128-bit (13-character strings, 1234567890123). Enter these as either
ASCII (12345) or Hex (0x 3132333435).
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 802.1x au-
thentication with EAP.
