Abstract
A Wi-Fi security authentication method and a communication apparatus are disclosed. In the method, an access point (AP) receives a first access request from a supplicant, where the first access request carries a first parameter, and the first parameter is a parameter generated by the supplicant based on a generator of a cyclic group and a first random number; generates a second random number, generates a second parameter based on the second random number and the generator of the cyclic group, and sends the second parameter to the supplicant; generates a second pairwise master key based on the second random number, the first parameter, the second parameter, and a first target random key; and performs a four-way handshake authentication procedure with the supplicant based on the first pairwise master key and the second pairwise master key.
