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 template of next-generation WPA3 wireless networks.

The standard will replace WPA2, a security protocol that almost exists decades and is built in to protect almost every wireless device today, including phones, laptops, and Internet of Things (IoT) devices.Qualcomm

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

This week, Qualcomm announced that it will integrate WPA3 across its portfolio of mobile and networking products that it manufactures, including chipsets for routers, smartphones, tablets and PCs. So soon we will see the successor of WPA2, the security protocol that can be broken by the famous Key Reinforcement Attack (KRACK) 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 protocol Standard (AES). Συγκεκριμένα, χρησιμοποιεί ένα handshake τεσσάρων κατευθύνσεων για να εμποδίσει κάθε πιθανή παρακολούθηση της κυκλοφορίας δικτύου μεταξύ ενός Wi-Fi access point (όπως το router) και ενός Wi-Fi client (όπως ένα smartphone ή ένα laptop). Η κρυπτογράφηση εμποδίζει θεωρητικά τις man-in-the-middle that attempt to “catch” data in transit.

But WPA2 is not perfect. Last October, security researchers uncovered KRACK, a vulnerability that interferes with the initial handshake between a device and the router in a way that allows intruders to view, decrypt, or even manage 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 a one-touch setup that will make it easier to protect devices without screens (Internet of Things devices and smart speakers like Google Home and Amazon's Echo).

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

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

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

As Qualcomm says Press release which he published, is the first company to announce the implementation of WPA3. The company says it will incorporate support for the new protocol in Snapdragon 845 in June and Qualcomm's Access Point platforms in July.
