Which of the following statement about the advantages of WPA3 is incorrect?
- A. Potential for dictionary attacks
- B. Even if the attacker obtains the intermediate key. the data cannot be decrypted
- C. Meet NSA/SuiteB security requirements of governments and banks
- D. Open SSID data can be encrypted
Answer: A
Explanation:
Explanation
WPA3 is a new security protocol for wireless networks that provides enhanced security and privacy features compared to WPA2 . One of the advantages of WPA3 is that it eliminates the potential for dictionary attacks, which are a type of brute-force attack that tries to guess passwords by using a list of common words or phrases
. WPA3 uses a more robust authentication mechanism called Simultaneous Authentication of Equals (SAE), which prevents offline password cracking attempts . The other statements are correct advantages of WPA3.
WPA3 can encrypt data on open SSIDs using Opportunistic Wireless Encryption (OWE), which creates a unique encryption key for each user without requiring any credentials . WPA3 also meets the NSA/SuiteB security requirements of governments and banks, which specify the use of strong encryption algorithms such as AES-256 and Elliptic Curve Cryptography (ECC) . WPA3 also ensures that even if an attacker obtains the intermediate key during the handshake process, they cannot decrypt the data or derive the session key, thanks to a feature called forward secrecy .
