In the world of wireless networking, security is a top priority. As attackers grow more sophisticated, so must our defences. One of the latest enhancements to WiFi security is the SAE Public Key method, introduced in WiFi Certified WPA3. This mechanism strengthens the authentication process, particularly in open networks.
To understand SAE Public Key, we need to start with SAE – Simultaneous Authentication of Equals. SAE is a secure password-based authentication protocol used in WPA3..Unlike WPA2’s pre-shared key (PSK), SAE provides mutual authentication and protects against offline dictionary attacks, making it significantly more secure. SAE allows two parties to establish a shared key without transmitting the password. Even if someone captures the traffic, they can’t use it to guess the password offline.
But what exactly is SAE Public Key, and why should you care?
This question was the focus of our Senior pre-sales consultant and Certified Wireless Network Expert, Lee Wright's presentation at Ekahau's WiFi Design Day.
In the video below, Lee delves into why there are so many bad practices associated with WiFi passwords and as WiFi threats continue to evolve how adopting technology like SAE Public Key can help keep your network one step ahead.

FAQs
What is shared authentication of equals (SAE)?
SAE is a password-based authentication protocol.
It replaces the older WPA2 pre-shared key (PSK) method.
How does SAE work?
SAE proves you know the Wi-Fi password without ever sending it, making Wi-Fi connections much safer than older WPA2 pre-shared key methods.
How does SAE work in WPA3 networks?
In WPA3 networks, SAE allows devices and access points to securely prove they know the Wi-Fi password, generate unique session keys, and protect against offline attacks, making your wireless network much safer than WPA2.
What are the benefits of SAE?
SAE provides stronger authentication, forward secrecy, and protection for shared networks, while being simple to manage and future-ready.
Securing your Wi‑Fi with SAE is an important step, but implementing it correctly requires expert knowledge and careful configuration. Redway Networks can help by designing and deploying WPA3 networks that use SAE authentication, ensuring your passwords are never transmitted, and each session is uniquely encrypted. Our team also optimises your Wi‑Fi performance, segments your network for security, and provides ongoing monitoring to prevent unauthorised access. Whether you need a Wireless Network Audit, professional Wi-Fi design and installation, or managed network support, we make sure your business Wi‑Fi is resilient, secure, and future-ready.
