Ltd., Qingdao 266000, China) Abstract: The interconnect architecture and method of modern intelligent home furnishing devices are introduced. The problems of power line communication’s encryption method in current intelligent home furnishing devices are discussed. A NFC-based encryption method of power line communication is proposed. The NFC card’s UID is used by this method to produce network member key and to complete the encryption process of PLC link. Through actual measurement, the current problems of power line communication’s encryption method is resolved well by the NFC-based method, the convenience, accuracy, and stability levels of NFC card reading process are increased. The method’s safety level is high, and has strong interference restraining ability towards outside interference.
