Question

Wi-Fi Protected Access (WPA) is a data encryption method for WLANs based on 802.11 standards. Temporal Key Integrity Protocol (TKIP) enhances WEP by adding a rekeying mechanism to provide fresh encryption and integrity keys. Temporal keys are changed for every____________.

Options

A5,000 packets
B10.000 packets
C15,000 packets
D20.000 packets

Explanation

TKIP was introduced as part of WPA to address WEP's critical weakness of using static encryption keys. One of TKIP's core enhancements is automatic key rotation: temporal (session) keys are refreshed every 10,000 packets. This frequent rekeying drastically limits the amount of data an attacker can capture under a single key, making cryptographic attacks like the FMS attack (used against WEP) impractical. Even if an attacker begins to crack a key, it will have already been rotated before enough packets are captured. The other options (5,000 / 15,000 / 20,000) do not match the defined TKIP specification.
