Abstract

The invention provides a shared household appliance lease authorization control method and device, and the method comprises the steps: building a connection between a household appliance and terminaldevice through a preset WIFI module, and obtaining a pre-stored private key corresponding to the identification information of the household appliance; encrypting the current first system time by using a private key to generate a payment token, and sending the payment token, the identification information and the lease time to the terminal device; receiving an encrypted message sent by the serverand fed back by the terminal device; and decrypting the encrypted message by using the private key to obtain the current time and the lease time, and judging whether the difference between the currenttime and the current second system time is within a preset time difference, and if so, controlling the household appliance to work according to the lease time. According to the method, the layout flexibility of the shared household appliances is greatly improved, the layout cost of the shared household appliances is reduced, malicious repeated lease attacks can be prevented, and the security is enhanced.
