WLAN Authentication and Privacy Infrastructure WAPI
WLAN Authentication and Privacy Infrastructure (WAPI) is a Chinese National Standard for Wireless LANs (GB 15629.11-2003).
Although it was allegedly designed to operate on top of WiFi, compatibility with the security protocol used by the 802.11 wireless networking standard developed by the IEEE is in dispute. Due to the limited access of the standard (only eleven Chinese companies had access), it was the focus of a U.S.-China trade dispute. Following this it was submitted to, and rejected by the ISO. It was resubmitted to ISO in 2010, but was cancelled as a project on 21 November 2011 after being withdrawn by China. Part of the reason for withdrawal is thought to be the well documented observations by IEEE representatives that showed WAPI was equivalent to a small subset of IEEE 802.11i based systems.
