step S3: opening a mobile phone App, selecting an open SSID by a user, and inputting a password to connect with an open wireless network of a gateway;
step S4: encrypting the open SSID and the password, and broadcasting the encrypted SSID and the password to all intelligent home terminals;
step S5: the intelligent home terminal receives and decrypts the SSID and the password, and then is connected to the home gateway open type wireless network;
step S6: the intelligent home terminal broadcasts or unicasts a connection success message to the mobile phone;
step S7: the mobile phone App acquires information of the intelligent home terminal;
step S8: a user determines an intelligent terminal which is allowed to be accessed to an intelligent home networking on an App;
step S9: the gateway adds the allowed intelligent home terminal into a white list system hiding the SSID (namely the intelligent home network);
step S10: the gateway sends down the encrypted hidden SSID name and password;
step S11: the intelligent home terminal disconnects the current open SSID connection and then is connected with the hidden SSID wireless network;
step S12: and the intelligent home terminal reports the networking success message, and the networking is successful.
Fig. 3 shows a specific flow of the secondary access part of the smart home terminal security networking method according to fig. 1. The specific process comprises the following steps.
