Which algorithms are used behind WPA, WPA2, and WPA3?

• A. DES and RSA
• B. MD5 and SHA-1
• C. TKIP and AES-CCMP
• D. 3DES only

Answer: (C)

The main idea here is the encryption schemes used by the WPA family. WPA introduced TKIP as a fix over the weaknesses of WEP, providing per-packet key mixing to improve security. WPA2 then standardized AES-based CCMP as the preferred method for protecting data, with TKIP available mainly for backward compatibility. WPA3 continues to rely on strong AES-based encryption, with newer modes like GCMP in Enterprise deployments, but the common thread is AES-based protection alongside TKIP support in older implementations. That’s why the pair TKIP and AES-CCMP is the best match: they represent the encryption approaches historically used across WPA, WPA2, and more recent WPA3 deployments. The other options don’t fit because DES and RSA are not the primary data-encryption methods used in these WPA standards (DES is outdated and RSA is public-key cryptography, not used for WPA data encryption). MD5 and SHA-1 are hash functions used for integrity, not for encrypting the wireless data. 3DES is an older cipher not employed as the standard encryption method in these WPA generations.
