A smart home user authentication method, user terminal and central control device

Abstract

The present invention discloses a smart home user authentication method, a user terminal and a smart home center control unit. The method comprises: initiating an authentication request to a smart home system; determining forward authentication public keys corresponding to the current moment, and obtaining a first public key; sending the first public key to the smart home system, wherein when the smart home system receives the first public key, the smart home system executes the following steps: determining forward authentication private keys corresponding to the current moment, obtaining the first private key, determining whether the first public key is matched with the first private key or not, if the first public key is matched with the first private key, performing authentication of the user terminal, or else, forbidding the authentication of the user terminal; and allowing different forward authentication public keys to correspond to different moment information, and allowing different forward authentication private keys to correspond to different moment information. The smart home user authentication method, the user terminal and the smart home center control unit can greatly improve the safety of the smart home user authentication process and fully maintain users' personal and property safety.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a smart home user authentication method, a user terminal and a central control device. Background technique [0002] At present, with the rapid development of the Internet of Things technology, smart home technology has been vigorously developed, and more and more home devices have been added to the smart home system. Users can remotely control the smart home devices at home through the user terminal in their hands. It has greatly improved the intelligence level of the home system. [0003] Before the user attempts to remotely control the smart home device through the user terminal, the smart home system needs to perform an authentication operation on the user terminal. Only after the authentication is passed, the user terminal is allowed to remotely control the smart home device. [0004] When the current smart home system authenticates the user terminal, it authenticates th...
