	TKIP Overview
		TKIP is a suite of algorithms that works as a "wrapper" to WEP, which allows users of legacy WLAN equipment to upgrade to TKIP without replacing hardware.
		TKIP uses the original WEP programming but "wraps" additional code at the beginning and end to encapsulate and modify it.
		While TKIP is useful for upgrading security on devices originally equipped with WEP, it does not address all of the security issues facing WLANs and may not be reliable or efficient enough for sensitive corporate and government data transmission.

	¿Cuál es TKIP (protocolo dominante temporal de la integridad)?
		TKIP (protocolo dominante temporal de la integridad) es parte de un estándar de bosquejo del grupo de funcionamiento de IEEE 802.11i.
		TKIP es un realce a la seguridad de WEP (aislamiento equivalente atada con alambre).
		Antes de TKIP, era posible realizar un ataque sabido del texto cifrado contra WEP después de recoger una gran cantidad de paquetes.

	TKIP - Wikipedia, the free encyclopedia
		This was necessary because the breaking of WEP had left WiFi networks without viable link-layer security, and the solution to this problem could not wait for the replacement of deployed hardware.
		TKIP ensures that every data packet is sent with its own unique encryption key.
		Also TKIP hashes the initialization vector (IV) values, which are sent as plaintext, with the WPA key to form the RC4 traffic key, addressing one of WEP's largest security weaknesses.

	What is TKIP (Temporal Key Integrity Protocol)?
		TKIP (Temporal Key Integrity Protocol) is part of a draft standard from the IEEE 802.11i working group.
		TKIP utilizes the RC4 stream cipher with 128-bit keys for encryption and 64-bit keys for authentication.
		Before TKIP, it was possible to perform a known ciphertext attack on WEP after collecting a large number of packets.

	WPA-TKIP and You; Why WEP is, rightfully, Dead - Short-Media Forums
		TKIP is the successor to WEP, and although WEP is optional in standard Wi-Fi, TKIP is required in WPA (Which means, to make your WPA network function, it's inherently secure).
		The TKIP encryption algorithm is stronger than the one used by WEP but works by using the same hardware-based calculation mechanisms WEP uses.
		TKIP generation is extremely quick, and even if all WLAN clients used the same cycling TKIP key, it changes too quickly to be jacked and hacked.

	UNINETT: WLAN - TKIP
		Like WEP, TKIP uses the RC4 stream cipher as the encryptor and decryptor and all involved parties must share the same secret key.
		TKIP also uses an Initialization Vector (IV) of 48-bit and uses it as a counter.
		The new MIC for TKIP is computed by a new algorithm called "Michael", made by Niels Ferguson.

	CommsDesign - Diving into the 802.11i Spec: A Tutorial
		TKIP and CCMP are both called out in the standard and the standard is written in such a way that it is extensible to support the addition of new encryption protocols should they be required in the future.
		TKIP was designed to address all the known attacks and deficiencies in the WEP algorithm while still maintaining backward compatibility with legacy hardware.
		As with TKIP, the temporal key is derived from the master key that was derived as part of the 802.1X exchange discussed previously.

	802.11 Security Beyond WEP
		The temporal key integrity protocol (TKIP), initially referred to as WEP2, is an interim solution that fixes the key reuse problem of WEP, that is, periodically using the same key to encrypt data.
		TKIP combines the temporal key with the client's MAC address and then adds a relatively large 16-octet initialization vector to produce the key that will encrypt the data.
		TKIP uses RC4 to perform the encryption, which is the same as WEP.

	» 2004 » December \| George Ou \| ZDNet.com
		Even though the WPA standard brought us TKIP encryption in 2003 and the 802.11i standard brought us AES encryption this year, many organizations and enterprises are still using Dynamic WEP to encrypt their WLAN data to keep hackers from seeing sensitive data or gain unauthorized network access.
		TKIP was not a Band-Aid for WEP, it was a rewrite of the WEP algorithm which required driver- and firmware-level upgrades on all Wi-Fi equipment.
		If neither TKIP or AES is possible, resort to VPNs where theWLAN is put in to an untrusted network where all clients must VPN in to the trusted network using 3DES or AES encryption and strong certificate or OTP token based authentication.

		TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs.
		TKIP provides per-packet key mixing, a message integrity check and a re-keying mechanism, thus fixing the flaws of WEP.

		TKIP adds four new algorithms to WEP: a Message Integrity Code (MIC) called Michael, an Initialization Vector (IV) sequencing discipline, a key mixing function and a re-keying mechanism.
		He indicated that TKIP was not intended in any sense to be a cryptographic hash function.

	Diving into the 802.11i Spec: A Tutorial
		Above TKIP and CCMP sits 802.1x, a standard for port based access control developed by a different body within the IEEE 802 organization.
		A WLAN that supports the simultaneous use of WEP along with the CCMP or TKIP encryption protocols is called a transitional network and is assumed to be a temporary configuration for the purposes of converting all clients to a TKIP- or CCMP-based security solution.
		It was designed to be made available as a firmware or software upgrade to existing hardware so that users would be able to upgrade their level of security without replacing existing equipment or purchasing new hardware.

	What are the Key Features of WPA Security?
		Temporal Key Integrity Protocol (TKIP) is used to wrap WEP in sophisticated cryptographic and security techniques to overcome most of its weaknesses.
		TKIP includes a message integrity code (MIC) at the end of each plain text message to ensure messages are not being spoofed.
		TKIP was a pragmatic compromise that allows organizations to deploy better security while AES-capable equipment is being designed, manufactured, and incrementally deployed.

	Configuring Security
		The CCMP (AES) and TKIP encryption algorithms used with WPA modes are far superior to the RC4 algorithm used for Static WEP or IEEE 802.1x modes.
		TKIP is the only encryption algorithm that is being tested in Wi-Fi WPA certification.
		The TKIP process more frequently changes the encryption key used and better ensures that the same key will not be re-used to encrypt data (a weakness of WEP).

	Wi-Fi Protected Access Data Encryption and Integrity - The Cable Guy – November 2004
		TKIP and Michael use a set of temporal keys that are derived from a master key and other values.
		TKIP uses the IV as a frame counter to provide replay protection.
		Unlike WEP, which uses a single key for unicast data encryption and typically a separate key for multicast and broadcast data encryption, WPA uses a set of four different keys for each wireless client-wireless AP pair (known as the pairwise temporal keys) and a set of two different keys for multicast and broadcast traffic.

		When either aes-ccmp, or TKIP are used, the PC's 802.11g wireless client software reports that both the Pairwise and Group ciphers are using either aes-ccmp or TKIP.
		Is it correct that using aes-ccmp TKIP allows for a greater number of possible keys (than TKIP), that the algorithm is virtually unbreakable when 256 bits are used, and that this would be the preferred over TKIP.

		The solution, as designated within TKIP, was to split the IV value into two parts; a 16-bit value that is used to fill the 24-bit IV field and a 32-bit value that is appended to the data prior to the WEP encryption process.

		TKIP works on top of WEP, offering stronger security than WEP, and increased assurance that your data will not be compromised.
		TKIP offers new encryption algorithms, and constantly changes the encryption keys making them harder for wireless hackers to capture them.
		With TKIP, the encryption keys are also encrypted themselves so you would first need to decrypt the key, before you can use the key to decrypt the network traffic.

	TKIP - Wikipédia
		TKIP (Temporal Key Integrity Protocol) est un protocole de communication utilisé pour la protection et l'authentification des données transitant sur un réseau WiFi.
		La sécurisation des réseaux déjà déployés étant vitale et le remplacement de tout le matériel existant peu réaliste TKIP (prononcé "ti-kaïp") emploie des solutions techniques proches de WEP (utilisation de l'algorithme de chiffrement RC4) mais sans les erreurs de conception de WEP.
		TKIP utilise du "key mixing" pour chaque paquet, une vérification de l'intégrité des messages et un mécanisme de mise à jours de la clé, éliminant ainsi d'autres problèmes de conception qui affectent WEP.
