WPA (Wi-Fi Protected Access) utilizes TKIP (Temporal Key Integrity Protocol) primarily as a rekeying mechanism to ensure that fresh encryption keys are generated and used throughout the communication session. This process mitigates the risks associated with using static keys over extended periods, which can be vulnerable to attacks.

TKIP dynamically generates a new key for each packet transmitted, effectively enhancing the security of the wireless network by ensuring that even if one key were to be compromised, it wouldn’t easily lead to the decryption of all data transferred over the network. This continual rekeying is crucial for maintaining the integrity and confidentiality of the data being transmitted.

While the other options such as data decryption, enhancing network speed, and reducing network traffic may involve aspects related to wireless security, they do not capture the primary function of TKIP within the WPA framework, which is focused on establishing a robust and dynamic security protocol through effective key management.
