Temporal Key Integrity Protocol (TKIP)
WPA uses TKIP to provide important data encryption enhancements including a per-packet key 
mixing function, a message integrity check (MIC) named Michael, an extended initialization 
vector (IV) with sequencing rules, and a re-keying mechanism. TKIP also provides for the 
following: 
• The verification of the security configuration after the...

Is WPA/WPA2 Perfect?
WPA/WPA2 is not without its vulnerabilities. Specifically, it is susceptible to denial of service 
(DoS) attacks. If the access point receives two data packets that fail the message integrity code 
(MIC) within 60 seconds of each other, then the network is under an active attack, and as a result, 
the access point employs counter measures, which include...

A bridge connects devices that all use the same kind of protocol. A router can connect networks that use 
differing protocols. It also reads the addresses included in the packets and routes them to the appropriate 
computer station, working with any other routers in the network to choose the best path to send the packets 
on. A wireless hub or access point adds a few capabilities such as roaming and...
