Research on cracking WIFI wireless network using Kali-Linux penetration testing software

In the paper, the penetration testing software aircrack-ng tool group was used to attack the wireless network, and the wireless network password of WPA/WPA2 encryption mode was cracked in the Kali-Linux virtual experimental environment. After enumerating the operation methods of 26 uppercase and lowercase letters or 9 numbers to the n-power by using computers and password dictionaries, the WiFi password can be quickly obtained with the current high-speed development of computer hardware. This method has the advantages of simplicity, speed, stability, and high security.
