Apple upgrades AirPort Extreme Wi-Fi security

Friday, 31 October 2003, 12:28 PM EST

Apple has updated its AirPort WLAN client and base-station software to add support for the Wi-Fi Protected Access (WPA) security protocol.

The new release, dubbed AirPort 3.2, only targets the company's 802.11g-based AirPort Extreme product range, not the earlier 802.11b implementation. The software includes a firmware upgrade for the AirPort Extreme access point and AirPort Extreme client code.

WPA is a subset of the as yet unratified 802.11i security standard. It provides all the features of the would-be standard, leaving out only those that require hardware acceleration. WPA provides Temporal Key Integrity Protocol (TKIP) data encryption support. TKIP essentially addresses the known vulnerabilities in the weak Wired Equivalent Privacy (WEP) system that's part of the 802.11b, g and a standards. WPA also adds user authentication schemes, including 802.1x and Extensible Authentication Protocol (EAP).
