智能家居设备电力线链路加密方法

摘要

介绍当前智能家居设备互联架构及方式，论述现有智能家居设备中电力线通信加密方法存在的问题。提出一种基于NFC的电力线通信加密方法，该方法使用NFC卡的UID生成网络密钥并对电力线网络链路进行加密。实测表明，该方法较好的解决了现有电力线通信加密存在的问题，增加了NFC读卡的便捷性、准确性、稳定性，具有较高的安全性，对外界干扰具有较强的抑制能力。%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.
