Which WPA3 feature provides forward secrecy, ensuring that a compromised session key cannot be used to decrypt previously captured traffic?
Protected Management Frames (PMF)
Opportunistic Wireless Encryption (OWE)
Advanced Encryption Standard (AES) with 192-bit keys
Simultaneous Authentication of Equals (SAE)
The correct answer is Simultaneous Authentication of Equals (SAE). SAE is the key exchange mechanism introduced in WPA3 to replace the Pre-Shared Key (PSK) method used in WPA2. SAE is based on a Diffie-Hellman key exchange, which provides forward secrecy by generating a unique session key for each connection. This ensures that even if one session key is compromised, it cannot be used to decrypt past traffic. While WPA3 uses strong encryption like AES, mandates Protected Management Frames (PMF), and introduces Opportunistic Wireless Encryption (OWE) for open networks, it is SAE that specifically delivers the forward secrecy feature for authenticated networks.
