WIRELESS NETWORK CONNECTION METHOD, WIRELESS NETWORK APPARATUS AND WIRELESS NETWORK ACCESS POINT (AP) APPLYING THE METHOD

A wireless network connection method includes the following steps: a wireless network access point (AP) that receives apparatus identification information of a wireless network apparatus through a wireless network. The wireless network AP generates a temporary encryption key according to the apparatus identification information and AP identification information of the wireless network AP. The wireless network AP encrypts a network transmission key according to the temporary encryption key to generate an encrypted key. The AP identification information and the encrypted key are transmitted to the wireless network apparatus. The wireless network apparatus generates the temporary encryption key according to the apparatus identification information and the received AP identification information. The wireless network apparatus decrypts the encrypted key according to the temporary encryption key to generate the network transmission key. The wireless network apparatus establishes a security connection with the wireless network AP according to the network transmission key.
