Apparatus and method for transferring network access information of smart household appliances

An apparatus for transferring network access information of smart household appliances, comprising:

• a registration detection unit for checking whether encrypted network access information of a smart household appliance is included in received data, and detecting the received data as data to be registered if the encrypted network access information of the smart household appliance is included in the received data;
• a storage unit for, if the data to be registered is detected by the registration detection unit, storing the encrypted network access information of the smart household appliance from the received data;
• a request detection unit for detecting whether the received data is data indicating that the smart mobile terminal requests network access information of a smart household appliance;
• a search and generation unit for, if request data has been detected by the request detection unit, searching the storage unit for encrypted network access information of a smart household appliance corresponding to the request data, and generating data that is transmittable to the smart mobile terminal, based on the encrypted network access information of the smart household appliance that has been found;
• and
• a transmission unit for transmitting the data generated by the search and generation unit to the smart mobile terminal.

A method for transferring network access information of smart household appliances, comprising:

• encrypting, by an indoor IP sharer, network access information of a smart household appliance using an encryption key;
• generating, by the indoor IP sharer, data to be transmitted to a smart grid service provider server, using the encrypted information and an ID of a user;
• transmitting, by the indoor IP sharer, the generated data to the smart grid service provider server;
• receiving and storing, by the smart grid service provider server, the user ID and the encrypted network access information of the smart household appliance;
• generating, by a smart mobile terminal, a message requesting the encrypted network access information of the smart household appliance, and sending, by the smart mobile terminal, the message to the smart grid service provider server;
• and
• if the message is received, generating, by the smart grid service provider server, a response message based on the encrypted network access information of the smart household appliance corresponding to the received message, and sending, by the smart grid service provider server, the response message to the smart mobile terminal.
