Quizplus · Accepted Answer

TKIP uses a 128-bit per-packet key. This key is dynamically generated for each packet and is derived from a combination of the temporal key (TK) and other information, such as the source and destination addresses. The use of a per-packet key helps to improve security by making it more difficult for attackers to break the encryption.
