WPA3 (Wi-Fi Protected Access 3) is the latest security protocol for Wi-Fi networks, succeeding WPA2.
It was introduced to address vulnerabilities and enhance security features over its predecessor.
Here are some key features of WPA3:
- Enhanced Encryption: WPA3 improves encryption methods to provide stronger security for Wi-Fi networks. It introduces the use of the latest encryption standard, 256-bit Galois/Counter Mode Protocol (GCMP-256), which provides more robust protection against brute-force attacks.
- Individualized Data Encryption: WPA3 uses a feature called Opportunistic Wireless Encryption (OWE), also known as Enhanced Open, which provides encryption for unauthenticated open networks. It ensures that data transmitted over the network is encrypted, even if users haven’t provided a password or authentication credentials.
- Robust Password-Based Authentication: WPA3 offers improved security for password-based authentication. It uses Simultaneous Authentication of Equals (SAE), also known as Dragonfly, which replaces the pre-shared key (PSK) method used in WPA2. SAE protects against offline dictionary attacks and brute-force attacks by securely verifying passwords without exposing them.
- Protection Against Offline Attacks: WPA3 provides added protection against offline attacks by implementing resistance against offline password-guessing attacks. It includes a cryptographic mechanism that prevents an attacker from capturing Wi-Fi handshake data and using it for offline cracking attempts.
- Enhanced Public Wi-Fi Security: WPA3 introduces a new feature called Wi-Fi Enhanced Open, which is designed for public Wi-Fi networks. It encrypts traffic between the user’s device and the access point, protecting it from eavesdropping and enhancing security even when connecting to open, unencrypted networks.
WPA3 is designed to improve the security of Wi-Fi networks and address some of the vulnerabilities present in WPA2. However, it’s important to note that the adoption of WPA3 requires compatible devices and support from both the wireless router/access point and the client devices connecting to the network.
While there are many routers and adapters available in the market, not all of them support WPA3. As of September 2021,following are lists of routers, access points and adapters that support WPA3:
