As of July 2020, WPA3 is the latest iteration of the WPA standard, bringing enhanced security features and addressing vulnerabilities found in WPA2. WPA3 improves authentication methods and employs stronger encryption protocols, making it the recommended choice for securing Wi-Fi networks. [22]
[3] [4] The new standard uses 128-bit encryption in WPA3-Personal mode (192-bit in WPA3-Enterprise) [5] and forward secrecy. [6] The WPA3 standard also replaces the pre-shared key (PSK) exchange with Simultaneous Authentication of Equals as defined in IEEE 802.11-2016 resulting in a more secure initial key exchange in personal mode.
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 ...
WPA2 uses an encryption device that encrypts the network with a 256-bit key; the longer key length improves security over WEP. Enterprises often enforce security using a certificate-based system to authenticate the connecting device, following the standard 802.11X. In January 2018, the Wi-Fi Alliance announced WPA3 as a replacement to WPA2 ...
Wi-Fi Protected Access 2 (WPA2) security, [9] which aligns with IEEE 802.11i. WPA2 is available in two types: WPA2-Personal for consumer use, and WPA2 Enterprise, which adds EAP authentication. Optional: Tests corresponding to IEEE 802.11h and 802.11d. WMM Quality of Service, [10] based upon a subset of IEEE 802.11e.
Although it was allegedly designed to operate on top of Wi-Fi, compatibility with the security protocol used by the 802.11 wireless networking standard developed by the IEEE is in dispute. Due to the limited access of the standard (only eleven Chinese companies had access), it was the focus of a U.S.–China trade dispute .
[2] 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]
Wi-Fi Protected Access 2 (WPA2) ratified in 2004 is considered secure, provided a strong passphrase is used. The 2003 version of WPA has not been considered secure since it was superseded by WPA2 in 2004. In 2018, WPA3 was announced as a replacement for WPA2, increasing security; [147] it rolled out on 26 June. [148]
