Key Features of WPA3
WPA3 has several new features that make it more secure than older Wi-Fi standards:
Enhanced Encryption and Protection
WPA3 significantly increases cryptographic strength by implementing 128-bit encryption in standard setups and 192-bit encryption (WPA3-Enterprise) in networks requiring higher security.
This robust encryption makes it practically impossible for cybercriminals to crack passwords through brute-force attacks.
WPA3 also uses the 256-bit Galois/Counter Mode Protocol (GCMP-256) for encryption, providing a stronger defense against attacks.
Individualized Data Encryption
One of the key advancements of WPA3 is the use of individualized data encryption. This means that even if multiple devices are connected to the same Wi-Fi network, each device has its unique encryption keys, enhancing user privacy and security
Protection Against Offline Attacks
WPA3 includes protections against offline dictionary attacks, thanks to the Simultaneous Authentication of Equals (SAE) handshake. This mechanism replaces the Pre-shared Key (PSK) exchange process, mitigating risks associated with offline dictionary attacks and establishing a more secure initial key exchange
Simultaneous Authentication of Equals (SAE)
- SAE is a new way for devices to connect to Wi-Fi networks
- It uses the Dragonfly handshake to protect against dictionary attacks
- Each device gets its own encrypted connection to the network
Improved Device Provisioning
WPA3 simplifies the process of adding new devices to a network without the need for a shared password, using Wi-Fi Device Provisioning Protocol (DPP) to replace the less secure Wi-Fi Protected Setup (WPS).
Wi-Fi Enhanced Open
WPA3 introduces a “public network” mode designed to enhance the security of open and unsecured public Wi-Fi networks. This mode reduces the risk of data interception through features like Opportunistic Wireless Encryption (OWE) and Wi-Fi Enhanced Open, which provide unauthenticated data encryption.
- Improved security for public Wi-Fi networks
- Encrypts data even on open networks without a password
Forward Secrecy
WPA3 incorporates forward secrecy, ensuring that even if an attacker captures data, it cannot be used to decrypt future communications because each session uses a unique encryption key.
- This prevents attackers from decrypting old data if they get the Wi-Fi password
- Generates new encryption keys for each session
Easy Connect
WPA3’s Easy Connect feature is designed to make it easier to securely add IoT devices to your Wi-Fi network. Instead of typing in a password, you can use your phone to scan a QR code on the device. This sets up an encrypted connection between the device and your network.
- Simplifies the process of connecting IoT devices to Wi-Fi
- Uses QR codes to securely add devices to the network
Which Routers Support WPA3?
