Problems solved by technology

[0004] The development of the Internet of Things in recent years has gradually become large-scale, but there are still many problems that need to be overcome in the long-term development and evolution process. For example, in terms of device security, there is a lack of mutual trust mechanism between devices. All devices need and The data of the Internet of Things center is checked. Once the database collapses, it will cause great damage to the entire Internet of Things; in terms of personal privacy, the centralized management structure cannot prove its innocence, and incidents of personal privacy data being leaked occur from time to time; In terms of scalability, the current IoT data flow is aggregated into a single central control system. In the future, IoT devices will grow exponentially, and the cost of centralized services will be unaffordable. The IoT network and business platform need a new system expansion solution ; In terms of communication and collaboration, the global Internet of Things platform lacks unified technical standards and interfaces, which hinders the communication between multiple Internet of Things devices and produces multiple competitive standards and platforms; in terms of inter-network collaboration, at present, Much of the Internet of Things is a self-organizing network within operators and enterprises
The cost of establishing credit is high when it comes to collaboration across multiple operators, between multiple peers

Abstract

The invention discloses a block chain and Internet of Things cooperative work method, which comprises the following steps: forming an Internet of Things block chain by taking an Internet of Things server, an Internet of Things service gateway and an Internet of Things access gateway as nodes of the block chain; accessing the Internet of Things equipment to an Internet of Things access gateway, and sending an identity authentication request; the internet-of-things block chain performs identity authentication on the internet-of-things equipment according to the authentication process, and communication is performed on the internet-of-things equipment passing the identity authentication; encrypting the Internet of Things data by using a preset key to obtain an Internet of Things data ciphertext; sending the Internet of Things data ciphertext to each node on the block chain to carry out legality judgment on the Internet of Things data; and if the Internet of Things data ciphertext is legal, writing the Internet of Things data ciphertext into the Internet of Things block chain. According to the invention, the block chain and the Internet of Things work cooperatively to form the Internet of Things block chain, the Internet of Things block chain is a decentralized service platform, and the Internet of Things block chain supports the Internet of Things entities to cooperate with each other in a decentralized mode.

Description

technical field [0001] The invention relates to the field of data network technology, in particular to a collaborative working method of a block chain and the Internet of Things. Background technique [0002] The essence of the blockchain is a digital distributed ledger, which is built on the basis of a series of encryption algorithms, storage technologies, and peer-to-peer networks; it guarantees the integrity of recorded transactions in a peer-to-peer, non-tamperable and credible manner Authenticity, immutability and authenticity. A blockchain block is defined as a data set that has a certain trust mechanism and can perform read or write operations. The blockchain block stores transaction confirmation, contracts, storage, replication, security, and other related information. . [0003] The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted, and its sound, Various required information such ...
