Abstract

The invention discloses a data interaction method and device based on the Internet of Things. The method comprises the following steps: acquiring a first identity identifier and first encrypted data of first terminal equipment sent by the first terminal equipment, searching a first data set in a multi-order query table according to a first index position, searching a first decryption key in the first storage table according to the first storage position information under the condition that the first data set is searched in the multi-order query table, and under the condition that the first decryption key is found in the first storage table, decrypting the first encrypted data in the first data packet by using the first decryption key to obtain the original data. According to the invention,the technical problems of complex terminal key management and high development cost caused by dependence on a product key when the terminal key is managed through a cloud technology are solved.

Description

technical field [0001] The present invention relates to the field of computer internet of things, in particular, to a data interaction method and device based on internet of things. Background technique [0002] Cloud technology refers to a hosting technology that unifies a series of resources such as hardware, software, and network in a wide area network or a local area network to realize data calculation, storage, processing, and sharing. Cloud technology can be applied to medical cloud, cloud IoT, cloud security, cloud calling, cloud gaming, cloud education, cloud conference, cloud social networking, etc. [0003] Cloud Security refers to the general term for secure software, hardware, users, institutions, and secure cloud platforms based on cloud computing business model applications. The keys of a large number of terminals can be managed through the secure cloud platform. Use the same set of basic keys for all terminals of the same IoT product as one type, one secret....
