Abstract: Intelligent household is essential in people'lives, but because of the hacking of many products on the market today, the security of intelligent household is threatened. Multiterminal controlled secure intelligent butler system not only uses the proprietary protocol to combat wireless network intrusion and system vulnerability mining procedures to achieve multi-terminal data exchange security encryption transmission, at the same time, we establish a consensus environment, and use the consensus mechanism to record and verify the security state of access devices, and can accurately control terminal for safety certification, ensure the safety of the smart home system in the family. This system reduces the cost of establishing a security architecture and the requirements for computing power, and can better respond to the frequent occurrence of smart home security incidents.

Key words: consensus mechanism, smart home, security protocol, Arduino control, DES encryption
