Abstract: As the intelligent networking of smart home appliances becomes the mainstream, the data of smart home appliances is connected to the Internet, and a series of network security issues have been introduced, such as data eavesdropping, malicious control operations, and privacy leakage, which threaten user safety and personal information security. First introduce the network communication framework of smart home appliances. Under this framework, communication is divided into three ends, including cloud platform server, home appliance equipment, and mobile control end (application), targeting its binding scenarios, identity authentication scenarios, and communication Analysis of existing problems such as protection, we interface security, rights management, firmware security and code security. The main problems include communication security, authorization authentication, and key distribution. In order to prevent potential safety hazards, the channel should ensure the basic requirements of confidentiality, integrity, and availability, and reasonably allocate user access control permissions, and the entire system should have a certain degree of fault tolerance.
