PROBLEM TO BE SOLVED: To obtain a wireless LAN encryption communications system capable of preventing leakage of an encryption key and eavesdropping of encryption communication. SOLUTION: The wireless LAN encryption communication includes an access point 2, which is connected to a network 1 and where a table of random numbers 4 describing an encryption key and a rule for generating the encryption key by referring to the table of random numbers 4 are stored, and a client terminal 3 which is connected to the network 1 via the access point 2 by a wireless LAN and has the same table of random numbers and rule stored therein. The client terminal 3 refers to the table of random numbers 4 for generating the encryption key, in accordance with the rule and encrypts an authentication request signal by the encryption key and transmits the encrypted authentication request signal to the access point 2. When the authentication request signal is received, the access point 2 generates the encryption key by the same method to decrypt the received authentication request signal, and not only returns an approval signal but also connects the client terminal 3 to the network 1, when the client terminal 3 is authenticated.
