In theory, this type of dictionary attack takes less time and effort than attacking WEP. TKIP and LEAP 1-13 Evil-Twin Attack An evil-twin is a homemade wireless access point that masquerades as a legitimate access point to gather private information without the end user’s knowledge. The attacker positions the evil-twin in the vicinity of a legitimate access point and discovers what name and radio frequency that point uses. The attacker then sends out a radio signal using the same name. 11i encryption standard.

In the first phase, a session key is generated from a temporal key, the TKIP sequence counter (TSC), and the transmitter’s MAC address. Once this phase is completed, a value called the TKIP-mixed transmit address and key (TTAK) is created. This value is used as a session-based WEP key in the second phase. In the second phase, the TTAK and the IV are used to produce a key that encrypts the data. TKIP can be considered more safe than WEP because the key is using a different value. A flowchart of TKIP’s encryption can be seen in Figure 1-2.

Cain & Abel Cain & Abel is a password recovery tool for Windows.
