Question No. 4

Peter, a network defender, was instructed to protect the corporate network from unauthorized access. To achieve this, he employed a security solution for wireless communication that uses dragonfly key exchange for authentication, which is the strongest encryption algorithm that protects the network from dictionary and key recovery attacks.

Identify the wireless encryption technology implemented in the security solution selected by Peter in the above scenario.

Correct Answer: B

WPA3 is the latest standard of Wi-Fi Protected Access, which was released in 2018 by the Wi-Fi Alliance. WPA3 uses a new handshake protocol called Simultaneous Authentication of Equals (SAE), which is based on a zero-knowledge proof known as dragonfly. Dragonfly is a key exchange algorithm that uses discrete logarithm cryptography to derive a shared secret between two parties, without revealing any information about their passwords or keys. Dragonfly is resistant to offline dictionary attacks, where an attacker tries to guess the password by capturing the handshake and testing different combinations. Dragonfly is also resistant to key recovery attacks, where an attacker tries to recover the encryption key by exploiting weaknesses in the algorithm or implementation. Dragonfly provides forward secrecy, which means that even if an attacker manages to compromise the password or key in the future, they cannot decrypt the past communication. WPA3 also supports other features such as increased key sizes, opportunistic wireless encryption, and protected management frames, which enhance the security and privacy of wireless networks.
