Wi-Fi clients have been using the same security protocol for many years. The Wi-Fi Alliance just announced WPA3, a Wi-Fi security standard that will replace WPA2. the Wi-Fi Alliance is underway to certify new products that support WPA3, Seveal manufacturers such as Qualcomm has begun to make chips for phones and tablets, Cisco has also announced upcoming support that could even update existing devices to support the WPA3.

WPA2 is standard that administers what happens at the time you connect to a closed Wi-Fi network using a password. WPA2 outlines the protocol a router and Wi-Fi client devices use to perform the “handshake” to securely communicate. Unlike the original WPA standard, WPA2 requires implementation of strong AES encryption that is more difficult to crack. This encryption ensures that a Wi-Fi access point and a Wi-Fi can communicate wirelessly securely.


WPA3-certified devices will include features like improved protection when users choose weak passwords and improved security setup on devices with limited or no interface screens.

Other much needed features, WPA3 adds what it calls individualized data encryption, which means that your individual connection to an open wireless network will be encrypted, even if that network is not protected by an overarching password. This is a very big and absolutely necessary change.

The old WPA2 security has been proven vulnerable to hardware-level attacks and password vulnerabilities. To help prevent new vulnerabilities from affecting WPA, the WPA3 standard uses a new type of handshake that adds extra protection against password-crackers and similar brute force types of hacking.

WPA3 would have better relations with the Internet of Things. WPA2 was primarily designed to work with traditional devices such as phones and laptops with screens you could use to input passwords and control wireless settings. However, the emerging smart which don’t have screen to manage wireless connections. Hence, WPA3 includes new measures to configure security for devices without screens.

WPA2 uses 64-bit or 128-bit encryption, but WPA3 will improve this by having a 192-bit security suite – a technology it is aiming at governments, industry and defence. According to the Wi-Fi Alliance, this will bring "the latest in cryptographic strength".
