TKIP Temporal Key Integrity Protocol.
This protocol is part
of the IEEE 802.11i encryption standard for wireless
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
standard WEP. Weak points of WEP include: No
Initiation Vector (IV) reuse protection, weak keys,
no protection against message replay, no detection of
message tampering, and no key updates.
WEP Wired Equivalent Privacy encryption. With
preconfigured WEP, both the client CN3 and access
point are assigned the same key, which can encrypt
all data between the two devices. WEP keys also
authenticate the CN3 to the access point - unless the
CN3 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).
Key Management Protocols Terminology
Acronym Description
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/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.
WPA2 Wi-Fi Protected Access. Second generation of WPA
security. Like WPA, WPA2 provides enterprise and
home Wi-Fi users with a high level of assurance that
their data remains protected and that only
authorized users can access their wireless networks.
