Problems solved by technology

A blockchain-based autonomous interconnection method for Internet of Things devices (CN201711090605, public date: March 20, 2018) proposes a device-wide mutual trust based on the mutual trust relationship between devices. In the process, access requests are realized in the form of transaction requests. Due to the limitation of the blockchain network transaction mechanism, this method has serious delay

Embodiment 1

[0038] Such as figure 1 In the network deployment model shown, ENode (traditional gateway) builds a blockchain network responsible for maintaining the consistency of the ledger. The accounting node maintains the ledger through the following smart contracts, including: device management smart contracts, identity authentication service smart contracts and access control services Smart contract, SNode (Internet of Things equipment, user equipment) belongs to the P2P network responsible for specific production business; bookkeeping node ENode and light node SNode, product features: the operating system kernel running the blockchain node runs the modified IoT-oriented security Certified protocol stack; ENode is a general-purpose computer in the Internet, and these nodes jointly maintain the ledger; the difference between SNode and ENode is that it does not participate in the maintenance of the ledger, and only synchronizes some blocks to the local. IoT devices are light nodes in thi...

Abstract

The invention discloses a decentralized Internet of Things security authentication system, a device registration method, and an identity authentication method, which belong to the field of Internet and network technology. The system includes accounting nodes and light nodes, and Internet of Things devices are light nodes in the system; the core module of the system : Device certificate generation module, key management module, blockchain basic service module, security authentication service module and visual management module. The invention operates blockchain basic services, network basic services, key management, device certificate generation and security authentication services in the system kernel state, and based on this, complete protection of devices and communication security guarantees between devices can be provided. In addition, DDDOS can be provided Attack detection and defense solutions, point-to-point key distribution, and blockchain application generation and deployment services.

Description

technical field [0001] The present invention relates to blockchain technology, P2P technology, Internet of Things identity authentication technology, operating system (protocol stack) and information security (encryption and decryption technology), specifically the decentralized Internet of Things security authentication system, device registration method and identity authentication method , belonging to the field of Internet and network technology. Background technique [0002] The Internet of Things not only connects the physical world with the digital world, but also is the basis for the connection between people and things, and between things and things, enabling communication and information exchange between things and things, and between people and things. Connecting with people becomes more efficient and natural. Every change in the connection method will completely subvert the market. Ten billion-level companies like AT&T are representatives of the call network era,...
