Which of the following encryption methods use the RC4 technology? Each correct answer represents a complete solution. Choose all that apply.

Dynamic WEP uses RC4 as its stream cipher and improves on static WEP only by rotating encryption keys more frequently using 802.1X authentication, but the core RC4 algorithm remains unchanged.

TKIP was introduced under WPA as a stopgap replacement for WEP and deliberately retained RC4 to allow firmware upgrades on existing hardware, wrapping RC4 with per-packet key mixing and a Michael MIC for integrity.

Static WEP, the original 802.11 encryption method, uses RC4 with a fixed pre-shared key of 40 or 104 bits, making it the foundational RC4-based wireless protocol from which Dynamic WEP and TKIP evolved.

CCMP uses AES in Counter Mode with CBC-MAC for both encryption and integrity, replacing RC4 entirely and forming the basis of WPA2 security - it shares no dependency on the RC4 cipher.
