TKIP is correct

WPA1 (Wi-Fi Protected Access 1) uses TKIP (Temporal Key Integrity Protocol) encryption for data protection. TKIP is an encryption protocol that was designed to provide stronger security than the previous WEP (Wired Equivalent Privacy) encryption standard, which was known to have vulnerabilities. TKIP uses a combination of encryption techniques, including a per-packet key mixing function, to provide data confidentiality and integrity. However, TKIP is now considered insecure and has been replaced by AES (Advanced Encryption Standard) in modern Wi-Fi security protocols such as WPA2 and WPA3.

B is correct The WPA protocol implements the Temporal Key Integrity Protocol (TKIP). WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP. https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#:~:text=The%20WPA%20protocol%20implements%20the,devices%20and%20does%20not%20change.

Nice piece on Wireless Security https://www.techtarget.com/searchnetworking/feature/Wireless-encryption-basics-Understanding-WEP-WPA-and-WPA2

Authentication and Encryption Feature Support WPA WPA2 WPA3* Authentication with Pre-Shared Keys? Yes Yes Yes Authentication with 802.1x? Yes Yes Yes Encryption and MIC with TKIP? Yes No No Encryption and MIC with AES and CCMP? Yes Yes No Encryption and MIC with AES and GCMP? No No Yes Offical Cert Guide Vol 1 - page number 662 So TKIP and AES both of them corect but TKIP make more sense

WPA 2 and 3 use AES counter...

TKIP is the right answer!

The correct answer it's B

TKIP indeed

AES was not introduced until WPA2, it is not part of WPA1. https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access
