wpa_supplicant is a free software implementation of an IEEE 802.11i supplicant for Linux, FreeBSD, NetBSD, QNX, AROS, Microsoft Windows, Solaris, OS/2 (including ArcaOS and eComStation) [2] and Haiku. [3] In addition to being a WPA3 and WPA2 supplicant, it also implements WPA and older wireless LAN security protocols.
wpa_supplicant and hostapd come as a pair of complementary client and host for wireless access points. That is hostapd allows us to create access points from the command line, which allows one to share one's internet connection wirelessly, while wpa_supplicant allows us to scan and to connect to access points as a client in order to get onto ...
The four-way handshake [8] is designed so that the access point (or authenticator) and wireless client (or supplicant) can independently prove to each other that they know the PSK/PMK, without ever disclosing the key. Instead of disclosing the key, the access point (AP) and client encrypt messages to each other—that can only be decrypted by ...
A Wireless Supplicant is a program that runs on a computer and is responsible for making login requests to a wireless network. [1] It handles passing the login and encryption credentials to the authentication server. It also handles roaming from one wireless access point to another, in order to maintain connectivity.
WPA-Personal and WPA2-Personal remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. WPA passphrase hashes are seeded from the SSID name and its length; rainbow tables exist for the top 1,000 network SSIDs and a multitude of common passwords, requiring only a quick lookup to speed up cracking WPA-PSK.

FreeBSD 7.0 introduced full support for WPA and WPA2, although in some cases this is driver dependent. FreeBSD comes with drivers for many wireless cards and chipsets, including those made by Atheros , Intel Centrino , Ralink , Cisco , D-link , and Netgear , and provides support for others through the ports collection .
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.
The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.
