Question

Wi-fi protected access (wpa) fixes critical vulnerabilities in the earlier wired equivalent privacy (wep) standard. Understanding that WPA uses a combination of an RC4 stream cipher and Temporal Key Integrity Protocol (TKIP), this makes a wireless access point not vulnerable to which of the following attacks when related to encrypted wireless packets?

1) IV attacks
2) MAC flooding
3) URL redirection
4) NFC attacks

Answer 1

WPA is not vulnerable to IV attacks on encrypted wireless packets.

Step-by-step explanation:

Wi-Fi Protected Access (WPA) fixes critical vulnerabilities in the earlier Wired Equivalent Privacy (WEP) standard. Unlike WEP, which uses the RC4 stream cipher for encryption, WPA uses a combination of the TKIP protocol and the RC4 cipher. TKIP dynamically generates a new encryption key for each packet, making wireless access points not vulnerable to IV (Initialization Vector) attacks.
