The correct answer is C: AES-CCMP. WPA2 (Wi-Fi Protected Access 2) mandates the use of AES (Advanced Encryption Standard) as the cipher and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) as the data integrity/encapsulation protocol. AES-CCMP replaced the weaker RC4-TKIP used by
Question
WPA2 provides enterprise and Wi-Fi users with stronger data protection and network access control which of the following encryption algorithm is used DVWPA2?
Options
- ARC4-CCMP
- BRC4-TKIP
- CAES-CCMP
- DAES-TKIP
Explanation
WPA2 (Wi-Fi Protected Access 2) mandates the use of AES (Advanced Encryption Standard) as the cipher and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) as the data integrity/encapsulation protocol. AES-CCMP replaced the weaker RC4-TKIP used by the original WPA. RC4 is a stream cipher considered cryptographically weak; TKIP was a transitional protocol. WPA2 with AES-CCMP provides significantly stronger confidentiality and data integrity for wireless networks.
