Embodiment Construction

[0040] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] In this example, if figure 1 As shown, it is an overall schematic diagram of a block chain-based Internet of Things management and control method. In this block chain Internet of Things system, a client, two Internet of Things gateways, and an Internet of Things event operation smart contract (event contract ), a custom token generation contract (token contract), and two IoT devices connected to each gateway constitute the main blockchain architecture, where the client and the IoT gateway are respectively connected to the RPC server, and the RPC server serves The node is connected to the blockchain; the IoT device is identified by URI and broadcast on the chain, and the IoT gateway is connected to the corresponding IoT device through the URI identi...

Abstract

The invention discloses an Internet of Things management control method based on a block chain, which comprises the following steps: (1) constructing an Internet of Things network based on the block chain, and forming a basic framework by a block chain infrastructure, an RPC server, Internet of Things equipment, an Internet of Things gateway and a client for controlling the Internet of Things equipment; (2) deploying an event contract on the chain, and publicly broadcasting a contract address; (3) formulating a token-based access control mechanism, and setting user permission; and (4) authorizing the user to call the event contract to complete the Internet of Things operation event. According to the invention, an Internet of Things architecture based on a block chain is designed, participants and interactions thereof are defined, and control management on the Internet of Things chain is driven by events of a smart contract, so that remarkable security and availability advantages are provided for realizing a token-based access control mechanism for a management system and further expanding the token-based access control mechanism.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a management and control method for the Internet of Things based on blockchain. Background technique [0002] A blockchain system is a distributed ledger architecture in which a group of mutually distrusting nodes can agree on a common view of the non-erasable, tamper-proof, append-only ledger. In its basic form, a ledger consists of a list of transactions between users. Users can send new transactions to the blockchain network, and if those transactions are valid, they are eventually appended to the ledger by randomly selected dedicated nodes, called miners. Advanced forms of ledgers may also include programs known as smart contracts. Smart contracts are associated with some state that is also stored in the ledger. Users can interact with smart contracts using transactions, and can modify the contract state. [0003] A popular blockchain architecture that supp...
