A device access control method and device

Abstract

The invention relates to the field of smart home, and aims at providing a device access control method and apparatus. The control method comprises the following steps: firstly, a block chain node receives a device authorization query request sent by a control terminal apparatus; then the block chain node determines a corresponding current authorization version number according to the device authorization query request; secondly, the block chain node determines a corresponding device authorization transaction record according to the device authorization query request and the current authorization version number; if the device authorization transaction record is found, the block chain node judges whether the device authorization query request is consistent with the device authorization transaction record, otherwise, the block chain node directly sends response information of the device authorization query request to the control terminal apparatus; and finally the control terminal apparatus judges whether to send control instruction information to the corresponding device according to the received response information of the device authorization query request. By adoption of the method, an interconnection, mutual communication and mutual control function between Internet of Things open platforms can be achieved.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a device access control method and device. Background technique [0002] With the rise of smart home and Internet of Things technology, major smart home manufacturers and service providers have used their own superior resources to build their own IoT open platform, trying to introduce more service providers or equipment manufacturers to join their own platforms. Realize the interconnection, intercommunication and mutual control among devices, applications and services. At present, various open platforms of the Internet of Things are contending, but the interconnection and interoperability between the open platforms of the Internet of Things is basically impossible. For equipment manufacturers, if they want to access the open platform of the service provider with user resources, they need to implant the corresponding SDK provided by the service provider in their own equipment. If equip...
