Qualcomm added WPA3 to its devices since June

As we mentioned in a previous post, Wi-Fi Alliance, a joint venture comprised of various device makers such as Apple, Microsoft and Qualcomm, announced on January 9 the Next Generation Wireless Security Model WPA3.

The standard will replace WPA2, a security protocol that has been in place for almost two decades and is built to protect almost every wireless device today, such as phones, laptops, and IoT devices.Qualcomm

One of the key improvements to WPA3 is to solve a common security problem: open Wi-Fi networks. Open Wi-Fi networks at cafes and airports are very convenient but unencrypted, allowing anyone on the same network to monitor data sent from other devices.

This week, Qualcomm has announced that it will incorporate WPA3 into its portfolio of mobile and networking products, such as chipset for routers, smartphones, tablets and computers. So we will soon see the successor of WPA2, the security protocol that can be violated by the famous Key Reinforcement AttackKRACK) revealed at the end of last year.

What is WPA?

WPA, derived from Wi-Fi Protected Access, secures devices with an encrypted code using the Advanced Encryption Standard (AES) protocol. Specifically, it uses a four-way handshake to prevent any possible monitoring of network traffic between a Wi-Fi access point (such as a router) and a Wi-Fi client (such as a ή ένα laptop). Η εμποδίζει θεωρητικά τις επιθέσεις -in-the-middle that attempt to “catch” data in transit.

But WPA2 isn't perfect. Last October, security researchers uncovered KRACK, a which interferes with the initial handshake between a device and the router in such a way that allows attackers to view, decrypt or even manipulate network data.

Most of the new devices (phones, laptops and Wi-Fi routers) were updated with a new firmware that protects KRACK, but old devices are vulnerable.

The new WPA3 is expected to support one ρύθμισης με ένα πάτημα, κάτι το οποίο θα κάνει ευκολότερη την προστασία συσκευών χωρίς οθόνες (συσκευές του Internet of Things και έξυπνα ηχεία όπως το Google Home και το Echo της Amazon).

WPA3 supports a much stronger encryption algorithm than WPA2 – although it is intended for industrial, defense and government applications rather than homes and offices. Specifically, the new protocol includes a 192-bit security suite aligned with the CNSA (Commercial National Algorithm Suite), a feature requested by the Commission on National Security Systems (CNSS), for (NSA).

WPA3 will use a very strong handshake that is not vulnerable to like KRACK. It's called the Dragonfly protocol and it will enhance security when exchanging the network key between a device and the router.

WPA3 also imposes strict limits on the number of attempts that one can use to guess the network password. This means that even networks with weak passwords will be less vulnerable to brute force attacks.

As Qualcomm says Press release published, is the first company to announce the implementation of WPA3. The company says it will incorporate the του νέου πρωτοκόλλου στο 845, τον Ιούνιο, και στις πλατφόρμες Access Point της Qualcomm τον Ιούλιο.
