Ratification nears for 802.11i, the security update for Wi-Fi: 802.11i is the final version of a major security overhaul, parts of which were released based on its interim draft as Wi-Fi Protected Access (WPA) by the Wi-Fi Alliance last year. WPA was an interim measure to improve security in the short-run; 802.11i adds advanced encryption keys that government agencies will require, as well a few other miscellaneous pieces that will improve authentication handoff from one access point to another.
