Abstract

The invention requests to an Internet of Things information security protection method based on a block chain. The method comprises the following steps: a, dividing an Internet of Things information security protection system; b, carrying out data segmentation on the received data information of the Internet of Things; c, establishing an index of a data block for the segmented data; and d, storingthe data in a Hash value returned by the IPFS system for encryption, and storing the encrypted ciphertext in a block chain. According to the invention, massive Internet of Things data information canbe effectively stored, illegal users can be tracked illegally, and the data privacy of the Internet of Things can be protected.

Description

technical field [0001] The invention belongs to the fields of information security protection technology, block chain technology and Internet of Things technology, and in particular relates to a block chain-based Internet of Things information security protection method and system. Background technique [0002] The Internet of Things refers to connecting any item with the Internet through information sensing equipment in accordance with the agreed agreement for information exchange and communication, so as to realize intelligent identification, positioning, tracking, monitoring and management. [0003] The application of the Internet of Things is very extensive, and can be applied to various fields such as military, industry, agriculture, power grid and water network, transportation, logistics, energy saving, environmental protection, medical and health care, and smart home. But while the Internet of Things provides people with more applications, it also faces many security ...
