Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) 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.
TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP. [4] WPA also includes a Message Integrity Check, which is designed to prevent an attacker from altering
The primary enhancement over WPA is the inclusion of the AES-CCMP algorithm as a mandatory feature. Both WPA and WPA2 support EAP authentication methods using RADIUS servers and preshared key (PSK). The number of WPA and WPA2 networks are increasing, while the number of WEP networks are decreasing, [34] because of the security vulnerabilities ...
Protection-capable management frames are those sent after key establishment that can be protected using existing protection key hierarchy in 802.11 and its amendments. Only TKIP/AES frames are protected and WEP/open frames are not protected. The following management frames can be protected: Disassociate; Deauthenticate
After the PSK or 802.1X authentication, a shared secret key is generated, called the Pairwise Master Key (PMK). In PSK authentication, the PMK is actually the PSK, [6] which is typically derived from the WiFi password by putting it through a key derivation function that uses SHA-1 as the cryptographic hash function. [7]
As a result, only static WEP or WPA keys may be used in a WDS connection, including any STAs that associate to a WDS repeating AP. OpenWRT, a universal third party router firmware, supports WDS with WPA-PSK, WPA2-PSK, WPA-PSK/WPA2-PSK Mixed-Mode encryption modes. Recent Apple base stations allow WDS with WPA, though in some cases firmware ...

Connection will be made using a secret 64-bit WEP key known to both devices. Key Generation Phase: With both devices connected, the AP generates and transfers a unique key to the client, where an RC4 tunnel is created. The AP creates four SSIDs and encryption keys for AES, TKIP, WEP128, and WEP64 generated from a random key script.
