Wi-Fi Protected Access 3, or WPA3, is the most recent version of widely used wireless network security. When compared to the widely used WPA2 standard, it increases security while maintaining backward compatibility. WPA3 was released by the Wi-Fi Alliance later in 2018. Companies have been using WPA2 protocols since 2004, and the new regulation expand upon them. WPA3 offers forward secrecy, with personal mode supporting 128-bit encryption and corporate mode supporting 192-bit encryption. WPA3 employs a less dangerous first key exchange technique called simultaneous authentication of equals in place of pre-shared key exchange.
The main key features of WPA3 are it is management frame protection, Transition mode, And simultaneous authentication of Equal(SAE). So let us understand the main key features of WPA3 to better understand this topic.
WPA2 uses the AES standard rather than the RC4stream cipher, in contrast to WEP and WPA. WPA's TKIP is replaced by CCMP. In contrast, WPA3 is 128-bit encryption in WPA3 personal mode(192-bit in WPA3-enterprise) and forward secrecy. WPA3 also replaces the pre-shared key exchange with simultaneous authentication of equals, a more secure way to do an initial key exchange.
What are the main key features of WPA3?
Management Frame Protection
The unicast management frames are encrypted to stop unauthorized client authorization. As a result, WIDS/WIPS systems will depend more on alerting the system administrator about rogue or honeypot APs, for example, and will have fewer options to impose customers' policies using brute force methods.
Transition mode
The enhanced open, personal, and enterprise modes can all function in transition mode. For clients that do not support WPA3, this implies returning to WPA2.
Simultaneous authentication of equal(SAE)
Even in cases where password complexity criteria are not met, SAE offers a more secure password-based authentication and key agreement process. It guards against attacks using brute force and makes it much more difficult for someone to decrypt a session either during or after it has begun just by knowing the passphrase.
