快速初始鏈路建立（FILS）：加速安全的無線區域網路（WLAN）存取
In today's digital age, users expect instant and seamless connectivity, especially when using wireless local area networks (WLANs). As the number of mobile and IoT devices continues to rise, the demand for faster and more efficient wireless connectivity has become more pressing. Traditional Wi-Fi connection procedures, though secure, often suffer from noticeable delays during the initial link setup. To address this issue, the IEEE introduced a solution in the form of the Fast Initial Link Setup (FILS) protocol, defined under the IEEE 802.11ai specification. FILS is designed to reduce connection delays without compromising the security and integrity of the authentication process.
