WPA Mode

• WPA

o WPA addresses all known vulnerabilities in WEP, the original, less secure 40 or 104-bit encryption

scheme in the IEEE 802.11 standard. WPA also provides user authentication, since WEP lacks any

means of authentication. Designed to secure present and future versions of IEEE 802.11 devices,

WPA is a subset of the IEEE 802.11i specification. WPA replaces WEP with a strong new encryption

technology called Temporal Key Integrity Protocol (TKIP) with Message Integrity Check (MIC). It also

provides a scheme of mutual authentication using either IEEE 802.1X/Extensible Authentication

Protocol (EAP) authentication or pre-shared key (PSK) technology. WPA was designed and has been

scrutinized by well-known cryptographers. It can be implemented immediately and inexpensively as a

software or firmware upgrade to most existing Wi-Fi CERTIFIED™ access points and client devices
