When implementing WLAN security， what are three benefits of using the Temporal Key Integrity Protocol （TKIP） instead of WEP？ （）

• A、 TKIP uses an advanced encryption scheme based on AES
• B、 TKIP provides authentication and integrity checking using Cipher Block Chaining Message Authentication Code （CBC-MAC）
• C、 TKIP provides per-packet keyingand a rekeying mechanism
• D、 TKIP provides message integrity check
• E、 TKIP reduces WEP’s vulnerabilities byusing different hardware encryption chipset
• F、 TKIP uses a 48 bit InitializationVector
