Answer Description

It generates a unique encryption key for each data packet sent over the network - This is correct. Temporal Key Integrity Protocol (TKIP) was designed as an improvement over WEP (Wired Equivalent Privacy) and addresses its vulnerabilities by generating a new encryption key for each data packet. This ensures greater security by making it harder for attackers to decrypt wireless communication.

It uses a fixed encryption key for the entire duration of a session - This describes WEP, which uses static encryption keys, a major vulnerability that TKIP was designed to overcome.

It applies a more robust encryption algorithm than AES - TKIP does not use AES (Advanced Encryption Standard) and is considered less secure than AES. TKIP was introduced as a temporary solution to improve WEP's security but was eventually replaced by the stronger WPA2 and AES-based encryption.

It is implemented in Bluetooth networks for secure communication - TKIP is used in wireless LANs (Wi-Fi networks) and is not implemented in Bluetooth networks. Bluetooth uses its own security protocols.
