When implementing WLAN security, using TKIP (Temporal Key Integrity Protocol) has several advantages over using WEP (Wired Equivalent Privacy). Here are the three benefits of using TKIP over WEP:
Per-packet keying and rekeying mechanism: TKIP uses per-packet keying, which means that each packet transmitted over the wireless network uses a unique encryption key. This provides a higher level of security compared to WEP, which uses a static encryption key for all packets. Additionally, TKIP provides a rekeying mechanism that automatically changes the encryption key at regular intervals, further increasing the security of the wireless network.
Authentication and Integrity Checking: TKIP provides authentication and integrity checking using CBC-MAC (Cipher Block Chaining-Message Authentication Code). This mechanism provides a higher level of security compared to WEP's CRC-32 (Cyclic Redundancy Check) integrity check, which is easily compromised.
Message Integrity Check: TKIP provides a Message Integrity Check (MIC) that is used to detect any unauthorized modification of the data during transmission. This is a critical security feature that is not provided by WEP. If an attacker tries to modify the data during transmission, the receiver will detect the modification and reject the packet.
Therefore, the correct options for the benefits of using TKIP instead of WEP are: B. TKIP provides authentication and integrity checking using CBC-MA. C. TKIP provides per-packet keying and a rekeying mechanism. D. TKIP provides message integrity check.
