Abstract: A Wi-Fi system and an associated channel allocation method are provided. The Wi-Fi system includes an access point (AP) device and a station (STA) device. The AP device collects AP-side capability information, and the STA device collects STA-side capability information. The STA device transmits STA-side capability information to the AP device. The AP device analyzes the AP-side capability information and the STA-side capability information to select an optimized channel accordingly. Later, the AP device and the STA device perform frame exchange procedures on the optimized channel. The throughput of the Wi-Fi system is improved because the selection of the optimized channel reduces potential conflicts.

The step of generating the frame includes applying integrity protection to a control information subfield, or applying integrity protection to an operating mode field included in a frame body of the frame.

Abstract: Techniques and examples pertaining to detection and prevention of broadcast and multicast packet attacking and uncovering to disconnect attackers in CCMP or TKIP-enabled wireless communications are described. A processor of a first network device establishes a wireless communication with a second network device in a wireless network. The processor detects a broadcast or multicast attack in the wireless network. The processor then notifies the second network device of the attack with a pairwise key encrypted frame.
