Wi-Fi Alliance has announced the introduction new security-based features for its family of Wi-Fi Certified technologies at CES 2018. After more than a decade, the WiFi Alliance has released the next specification of the security protocol known as WPA3. As well as addressing the issues surrounding KRACK, WPA3 is claimed to offer four key new capabilities over its predecessor: the introduction of techniques for improving security even when users pick too-simple passphrases, simplified configuration for headless devices which lack display capabilities, per-client rather than per-network encryption, and a new 192-bit security cipher suite created to align with the US Committe on National Security Systems’ Commercial National Security Algorithm (CNSA) requirements.
WPA3 employs individualized data encryption, which scramble the connection between each device on the network and the router, ensuring secrets are kept safe and sites that you visit haven’t been manipulated. The most notable problem for WPA2 was the recent discovery of several key management vulnerabilities in the 4-way handshake of its security protocol (aka – KRACK or Key Reinstallation Attacks). “Finally, a 192-bit security suite, aligned with the Commercial National Security Algorithm (CNSA) Suite from the Committee on National Security Systems, will further protect Wi-Fi networks with higher security requirements such as government, defense, and industrial”.
Apparently WPA3 will contain four new capabilities for personal and enterprise Wi-Fi networks. These are usually open and unencrypted, which means whoever uses them is quite vulnerable to snooping and data theft.
