Explanation

RC4 (Rivest Cipher 4) is a stream cipher used in both WEP and WPA with TKIP. WEP uses RC4 directly with static keys and weak IVs. WPA-Personal with TKIP (Temporal Key Integrity Protocol) was designed as an interim improvement over WEP - it still uses RC4 as the underlying cipher but adds per-packet key mixing and a message integrity check. WPA2 (both Personal and Enterprise) uses AES with CCMP, which replaced RC4 entirely and is considered secure.
