6.17 What is 802.1x Authentication?
802.1x is a framework for authenticated MAC-level access control, defines
Extensible Authentication Protocol (EAP) over LANs (WAPOL). The standard
encapsulates and leverages much of EAP, which was defined for dial-up
authentication with Point-to-Point Protocol in RFC 2284.
Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL
messages that convey the shared key information critical for wireless security.
6.18 What is Temporal Key Integrity Protocol (TKIP)?
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i
encryption standard for wireless LANs. TKIP is the next generation of WEP, the
Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP
provides per-packet key mixing, a message integrity check and a re-keying
mechanism, thus fixing the flaws of WEP.
6.19 What is Advanced Encryption Standard (AES)?
Security issues are a major concern for wireless LANs, AES is the U.S.
government’s next-generation cryptography algorithm, which will replace DES and
3DES.
6.20 What is Inter-Access Point Protocol (IAPP)?
The IEEE 802.11f Inter-Access Point Protocol (IAPP) supports Access Point Vendor
interoperability, enabling roaming of 802.11 Stations within IP subnet.
IAPP defines messages and data to be exchanged between Access Points and
between the IAPP and high layer management entities to support roaming. The
IAPP protocol uses TCP for inter-Access Point communication and UDP for
RADIUS request/response exchanges. It also uses Layer 2 frames to update the
forwarding tables of Layer 2 devices.
6.21 What is Wireless Distribution System (WDS)?
The Wireless Distribution System feature allows WLAN AP to talk directly to other
APs via wireless channel, like the wireless bridge or repeater service.
6.22 What is Clone MAC Address?
Clone MAC address is designed for your special application that request the clients
to register to a server machine with one identified MAC address.
Since that all the clients will communicate outside world through the WLAN Access
Point, so have the cloned MAC address set on the WLAN Access Point will solve
the issue.
