Temporal Key Integrity Protocol a protocol being considered for standardization in the draft IEEE 802.11i standard as a replacement for WEP. It has been endorsed by the Wi-Fi Alliance for use in Wi-Fi Protected Access (WPA).
An encryption standard used in security systems like IEEE 802.11i and WPA.
Temporal Key Integrity Protocol is an IEEE security standard that is part of the proposed 802.11i standard and the WiFi Alliance WPA. This scheme extends the encryption design of WEP and addresses the flaws of the former.
The encryption protocol used in WPA, a wireless LAN data encryption scheme. TKIP achieves considerably higher encryption strength as it updates encryption key every time a certain amount of data is transferred. see AES, WPA
TKIP (Temporal Key Integrity Protocol) is a security protocol defined in IEEE 802.11i specifications for WiFi networks (Wireless LAN) to replace WEP (an encryption technique). TKIP was designed to replace WEP without replacing legacy hardware. See als WiFi and WEP.
Temporal Key Integrity Protocol. An encryption protocol based on IEEE 802.11i specifications that changes the encryption key periodically to make it harder to crack. TKIP is intended to secure wireless LAN (Wi-Fi). Also see Wi-Fi and WPA.
Part of the WPA system to enhance wireless network security, TKIP dynamically changes the keys used to encrypt each packet of data on the wireless network. TKIP also uses a message integrity check to ensure that the keys have not been tampered with. Back
Temporal Key Integrity Protocol. The wireless security encryption mechanism in Wi-Fi Protected Access. TKIP uses a key hierarchy and key management methodology that removes the predictability that intruders relied upon to exploit the WEP key. It increases the size of the key from 40 to 128 bits and replaces WEP's single static key with keys that are dynamically generated and distributed by an authentication server, providing some 500 trillion possible keys that can be used on a given data packet. It also includes a Message Integrity Check (MIC), designed to prevent an attacker from capturing data packets, altering them and resending them. By greatly expanding the size of keys, the number of keys in use, and by creating an integrity checking mechanism, TKIP magnifies the complexity and difficulty involved in decoding data on a Wi-Fi network. TKIP greatly increases the strength and complexity of wireless encryption, making it far more difficult-if not impossible-for a would-be intruder to break into a Wi-Fi network. (See AES, WPA, WPA2). close
Temporal Key Integrity Protocol. A method for periodicaly rotating encrypting keys in order to improve WLAN system security.
Temporal Key Integrity Protocol is the next generation of WEP, the Wired Equivalency Protocol; TKIP offers an added form of encryption included in WPA that scrambles data based on a special algorithm and provides per-packet key mixing a message integrity check and a re-keying mechanism to make sure keys haven't been altered.
Temporal Key Integrity Protocol. an encryption protocol designed to provide more secure wireless encryption than WEP by making keys more difficult to crack. TKIP is the encryption mechanism for WPA, but is replaced by AES in 802.11i, which is also known as WPA2.
Temporal Key Integrity Protocol, also known as key hashing, is used as part of server-based EAP authentication.
Temporal Key Integrity Protocol. Also referred to as WEP key hashing. A security feature that defends against an attack on WEP in which the intruder uses the initialization vector (IV) in encrypted packets to calculate the WEP key. TKIP removes the predictability that an intruder relies on to determine the WEP key by exploiting IVs.

TKIP is a quick-fix method to overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. The TKIP (security) process begins with a 128-bit "temporal key" (which is) shared among clients and access points (APs). TKIP combines the temporal key with the (client machine's) MAC address and then adds a relatively large 16-octet initialization vector to produce the key that will encrypt the data. This procedure ensures that each station uses different key streams to encrypt the data. TKIP uses RC4 to perform the encryption. WEP also uses RC4. A major difference from WEP, however, is that TKIP changes temporal keys every 10,000 packets. This provides a dynamic distribution method that significantly enhances the security of the network.
An encryption key that's part of WPA. TKIP stands for Temporal Key Integrity Protocol. It's nominally weaker than the government-grade AES, but in the real world, TKIP is more than strong enough.
