Which of the following wireless security technologies continuously supplies new keys for WEP?

TKIP was developed as a software-based fix for WEP's critical vulnerability of using static, reusable encryption keys. It generates a unique 128-bit key per packet using a key mixing function, effectively supplying a continuous stream of new keys without requiring hardware replacement. This made it possible to patch WEP-based hardware through firmware updates.

MAC filtering is an access control mechanism that restricts which devices can connect to a network; it does not involve encryption keys or address WEP's key reuse problem.

WPA2 uses CCMP based on AES for encryption, which is a completely separate and stronger protocol that replaced WEP entirely rather than supplying it with new keys.

WPA is the overarching security protocol that incorporates TKIP; TKIP is the specific component within WPA responsible for continuous key generation, making A the more precise answer.
