 temporal key integrity protocol or tkip  was a stopgap 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 left wifi networks without viable link-layer security, and a solution was required for already deployed hardware. tkip is no longer considered secure and was deprecated in the 2012 revision of the 802.11 standard. == background == on october 31, 2002, the wi-fi alliance endorsed tkip under the name wi-fi protected access (wpa). the ieee endorsed the final version of tkip, along with more robust solutions such as 802.1x and the aes based ccmp, when they published ieee 802.11i-2004 on 23 july 2004. the wi-fi alliance soon afterwards adopted the full specification under the marketing name wpa2. tkip was deprecated by the ieee in january 2009. == technical details == tkip and the related wpa standard implement three new security features to address security problems encountered in wep protected networks. first, tkip implements a key mixing function that combines the secret root key with the initialization vector before passing it to the rc4 initialization. wep, in comparison, merely concatenated the initialization vector to the root key, and passed this value to the rc4 routine. this permitted the vast majo
