Abstract

The invention discloses a data interaction method and device based on the Internet of Things. Wherein, the method includes: obtaining the first identity of the first terminal device and the first encrypted data sent by the first terminal device; searching the first data set in the multi-level lookup table according to the first index position; In the case that the first data set is found in the multi-level lookup table, the first decryption key is searched in the first storage table according to the first storage location information; In the case of the first decryption key, use the first decryption key to decrypt the first encrypted data in the first data packet to obtain the original data. The invention solves the technical problems of complicated management of the terminal key and high development cost due to the need to rely on the product key when managing the terminal key through the cloud technology.

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. For all terminals of the same IoT product, use the same set of basic keys as one type, one secret...
