Temporal Key Integrity Protocol (TKIP / tiːˈkɪp /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware. This was necessary because the breaking of WEP had ...
Wi-Fi Protected Access. Wi-Fi Protected Access (WPA), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the ...
IEEE 802.11i-2004, or 802.11i for short, is an amendment to the original IEEE 802.11, implemented as Wi-Fi Protected Access II (WPA2). The draft standard was ratified on 24 June 2004. This standard specifies security mechanisms for wireless networks, replacing the short Authentication and privacy clause of the original standard with a detailed ...
In Shared Key authentication, the WEP key is used for authentication in a four-step challenge–response handshake: The client sends an authentication request to the access point. The access point replies with a clear-text challenge. The client encrypts the challenge-text using the configured WEP key and sends it back in another authentication ...
IEEE 802.11w is the Protected Management Frames standard for the IEEE 802.11 family of standards. Task Group 'w' worked on improving the IEEE 802.11 Medium Access Control layer. [1] Its objective was to increase security by providing data confidentiality of management frames, mechanisms that enable data integrity, data origin authenticity, and ...
The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup (WPS) originally, Wi-Fi Simple Config, is a network security standard to create a secure wireless home network. Created by Cisco and introduced in 2006, the purpose of the protocol is to allow home ...

The packet number is a 48-bit number stored across 6 octets. The PN codes are the first two and last four octets of the CCMP header and are incremented for each subsequent packet. Between the PN codes are a reserved octet and a Key ID octet. The Key ID octet contains the Ext IV (bit 5), Key ID (bits 6–7), and a reserved subfield (bits 0–4).
