Abstract: This paper introduces the four generations of Wi- Fi communication encryption technology represented by WEP, WPA-TKIP, WPA2-AES and WPA2 respectively. Through the principle analysis and discuss of the security risks faced by the encryption schemes in each stage, the characteristics of the encryption schemes in different stages and the process of gradually strengthening the security ofWi-Fi communication are described.

Key words: Wi-Fi, WEP, WPA, WPA2, WPA3, TKIP, AES, SAE, PMF
