Abstract: Smart Home products in the use of remote control is easy to be hijacked, local control easily invaded, which causes many other security risks. Making use of trusted thirdparty authentication technology in the Smart Home products, establishing trust relationships of Smart Home products, users mobile devices and services platform that is trusted cloud platform , thirdparty mutual trust based on mature PKI technology, asymmetric algorithm for the core technology to ensure that Smart home products only execute user instructions which are authenticated by trusted cloud platform . The deployment of Smart Home products is divided into the overall home product and intelligent single product, in the use of local control and remote control, different situations require trusted thirdparty authentication to ensure product security. In order to reduce the cost while adding a trusted thirdparty authentication mechanism, the protocol transformation on the basis of the MQTT protocol is also the best practice for the rapid application of the authentication technology to the smart home industry.
