Method, device and system for unique authorization of Internet-of-Things equipment based on OAuth

The invention discloses a method, a device and a system for unique authorization of Internet-of-Things equipment based on OAuth; on the premise that a user does not need to expose user's secret key to the third-party application, the access authorization to the third-party application is realized and the safety is improved effectively; moreover, the secret key is only stored and used in the application of one terminal equipment at any time and any place by means of the user's authorization, so that the uniqueness of the user's authorization is ensured; the equipment is only controlled by one terminal at the same moment and the equipment can work normally. The secret key is generated according to a plurality of parameters, so that the terminal mark of the mobile terminal equipment is guaranteed to be globally unique and is not changed along with the change of time and external environment, and the safety and reliability are improved greatly. The method, the device and the system for unique authorization of Internet-of-Things equipment based on OAuth can be widely applied to the application of the Internet of Things.
