WPA3 encryption Wi-Fi equipment
WPA3 encryption
— fundamental improvement to WPA2, introduced in 2018, addressing weaknesses identified in WPA2 in the 14 years since it went live. This standard introduced four key innovations:- Improved security for public networks. Unlike its predecessor, WPA3 encrypts the traffic between the gadget and the router / access point, even if the network is public and does not require a password.
- Protection against the KRACK vulnerability, which allowed hacking the WPA2 communication channel at the time the connection was established. The SAE algorithm is responsible for this protection — more advanced than the previously used PSK. In particular, when establishing a connection via SAE, both devices are considered equal (in PSK, the receiver and transmitter were clearly defined) — this does not allow an attacker to “wedge” between devices using KRACK methods.
- The Easy Connect feature makes it easier to connect to Wi-Fi networks for devices that do not have displays (in particular, smart home components). Each of these devices will have a QR code on the body, and to connect to the network, it will be enough to scan this code using a smartphone / tablet that is already connected to this network. However this function is not directly related to WPA3, WPA2 is sufficient for its operation; however, mass adoption of Easy Connect should be expected at the same time as WPA3.
- Improved encryption algorithms for sensitive data, suitable even for government agencies and defense enterprises. However, this feature is relevant mainly for the corporate version of WPA3 — and support for this version is indicated as "802.1x" (see below, in this case we are talking mainly about the personal version of this standard).
