The method for secure interaction of data of the internet of things as claimed in claim 4, wherein the original key is a built-in key bound with the MAC address when the terminal module of the internet of things leaves a factory, and the data key is a temporary key randomly generated by the terminal module of the internet of things.
6. The internet-of-things data security interaction method according to claim 1, wherein in the data security interaction protocol, data interaction is performed in the form of data blocks; the data block includes a plurality of data clusters, a data cluster includes a plurality of sectors, a sector includes a plurality of consecutive pages, and a page includes a plurality of bytes.
7. The method for safe interaction of data of the internet of things as claimed in claim 6, wherein one data cluster comprises 32 sectors, one sector comprises 32 continuous pages, and one page comprises 16 bytes.
8. The method for secure interaction of data of the internet of things according to claim 1, wherein the data synchronization of the terminal module of the internet of things and the access point device of the internet of things specifically comprises:
the Internet of things access point equipment sends a data synchronization request to the Internet of things terminal module;
responding to the data synchronization request, the Internet of things terminal module sends self state data to the Internet of things access point equipment in a data block form, and data updating is carried out on the Internet of things access point equipment;
and/or the presence of a gas in the atmosphere,
and responding to a control instruction, and updating data block information related to the control instruction in the Internet of things terminal module by the Internet of things access point equipment to control the Internet of things terminal module.
9. A data security interaction system of the Internet of things is characterized by comprising: the system comprises an Internet of things terminal module, internet of things access point equipment and an Internet of things verification cloud;
