WPA3 is designed to improve Wi-Fi security by enabling better authentication over WPA2, providing expanded cryptographic strength and increasing the resiliency of critical networks. The WPA3 protocol provides new features for personal and enterprise use, such as a harder-to-break 256-bit Galois/Counter Mode Protocol (GCMP-256), 384-bit Hashed-based Message Authentication Code (HMAC) and 256-bit Broadcast/Multicast Integrity Protocol Galois Message Authentication Code (BIP-GMAC-256). It's a major improvement over WPA2, as it provides increased protection of data that moves across personal and enterprise Wi-Fi networks. WPA3 (Wi-Fi Protected Access 3) is the third iteration of a security certification standard developed by the Wi-Fi Alliance. The more recent FragAttacks vulnerability affected all Wi-Fi security protocols from Wired Equivalent Privacy (WEP) to WPA3. Updates to WPA3 include better protection for simple passwords, encryption for open networks, and more secure encryption for enterprise-based networks. The newer standard also includes different capabilities for personal and enterprise use, as Wi-Fi networks differ in usage, purpose and security in these settings. The WPA3 protocol also supports security measures such as perfect forward secrecy (PFS), which produces a temporary private key exchange between clients and servers. WPA3 is designed to improve security for wireless networks. Learn how WPA3 compares to the previous wireless network standards: Wired Equivalent Privacy, WPA and WPA2. Personal mode lets users choose easy-to-remember passwords, while still providing increased security using PFS to protect data traffic. For example, WPA3-Personal networks offer increased protection against attempts at password guessing, while WPA3-Enterprise networks provide improved security protocols for networks. Learn more about the differences among WEP, WPA, WPA2 and WPA3, and see how to improve mobile hotspot security. WPA3 is a mandatory certification for Wi-Fi-certified devices and remains a standard for wireless security. Users who wish to use WPA3-approved devices must either buy a router that supports WPA3 or hope their device supports the new protocol. This mode focuses on improving protection for individual users by providing better security using SAE. Wi-Fi Easy Connect is another new feature in WPA3 that enables devices to connect quickly, even those without a screen or input method. Enterprise mode also has multiple EAP methods for authentication, 128-bit authenticated encryption, and 256-bit key derivation and confirmation, as well as 128-bit PMF.
