During this handshake, a Pairwise Transient Key (PTK) is generated for secure data exchange. [12] WPA2 employs the Advanced Encryption Standard AES with a 128-bit key, enhancing security through the Counter-Mode/CBC-Mac Protocol CCMP. This protocol ensures robust encryption and data integrity, using different Initialization Vectors (IVs) for ...
A major security flaw was revealed in December 2011 that affects wireless routers with the WPS PIN feature, which most recent models have enabled by default. The flaw allows a remote attacker to recover the WPS PIN in a few hours with a brute-force attack and, with the WPS PIN, the network's WPA/WPA2 pre-shared key (PSK). [ 3 ]
Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network.

IEEE 802.11i enhances IEEE 802.11-1999 by providing a Robust Security Network (RSN) with two new protocols: the four-way handshake and the group key handshake. These utilize the authentication services and port access control described in IEEE 802.1X to establish and change the appropriate cryptographic keys.
