In Shared Key authentication, the WEP key is used for authentication in a four-step challenge–response handshake: The client sends an authentication request to the access point. The access point replies with a clear-text challenge. The client encrypts the challenge-text using the configured WEP key and sends it back in another authentication ...
The Wi-Fi Alliance standardized these methods as Wi-Fi Protected Setup; however, the PIN feature as widely implemented introduced a major new security flaw. The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [48]
Wireless security. 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-2004, or 802.11i for short, is an amendment to the original IEEE 802.11, implemented as Wi-Fi Protected Access II (WPA2). The draft standard was ratified on 24 June 2004. This standard specifies security mechanisms for wireless networks, replacing the short Authentication and privacy clause of the original standard with a detailed ...
The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup ( WPS) originally, Wi-Fi Simple Config, is a network security standard to create a secure wireless home network . Created by Cisco and introduced in 2006, the point of the protocol is to allow home ...
Extensible Authentication Protocol ( EAP) is an authentication framework frequently used in network and internet connections. It is defined in RFC 3748, which made RFC 2284 obsolete, and is updated by RFC 5247 . EAP is an authentication framework for providing the transport and usage of material and parameters generated by EAP methods.
IEEE 802.11w is the Protected Management Frames standard for the IEEE 802.11 family of standards. Task Group 'w' worked on improving the IEEE 802.11 Medium Access Control layer. [1] Its objective was to increase security by providing data confidentiality of management frames, mechanisms that enable data integrity, data origin authenticity, and ...
In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. Key. To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms.
