Computer Hacking Forensic Investigator (CHFI) Practice Exam

The Temporal Key Integrity Protocol (TKIP) is designed to enhance Wi-Fi security, particularly in wireless networks that originally employed WEP (Wired Equivalent Privacy) encryption. WEP was found to have significant security flaws, primarily due to static keys that could easily be compromised. TKIP addresses these vulnerabilities by introducing dynamic key generation, which means that keys are changed frequently during a session, reducing the risk of key reuse and potential interception by attackers.

Additionally, TKIP incorporates a message integrity check that helps prevent tampering with packets. This level of security improvement was essential during the transition to more secure protocols since WEP had already been broadly adopted at that time.

In contrast, while Advanced Encryption Standard (AES) offers superior encryption for data and is indeed more secure than WEP, it does not directly enhance WEP’s security since it is a separate encryption standard. Secure Socket Layer (SSL) is primarily used for securing communications over a network, not specifically enhancing WEP. Lastly, Data Encryption Standard (DES) is an older encryption standard that has been largely replaced due to its vulnerabilities and does not provide the enhancements necessary for securing WEP.
