Block chain-based method for accessing power Internet of Things terminal

Abstract

The invention provides a Block chain-based method for accessing a power Internet of Things terminal, comprising the steps of: connecting a to-be-accessed power Internet of Things terminal to a masternode, and initiating an authentication request; the master node responding to the authentication request, and randomly selecting nodes that meet the condition of a threshold number from the block chain to form an authentication group; encrypting a public key G and an identity ID of the to-be-accessed power Internet of Things terminal by using a private key to obtain a digital signature ciphertextX, and sending the identity ID, a terminal public value R and the digital signature ciphertext X to the master node; the master node encapsulating and sending the authentication request information toa member node of the authentication group; the authentication group running PBFT consensus algorithm, and obtaining an authentication result by performing distributed authentication through two-two exchanging of the authentication information between the nodes of the authentication group; generating a new block in the block chain, and returning confirmation information to the to-be-accessed powerInternet of Things terminal; and the power Internet of Things terminal returning encrypted confirmation information to an access gateway. The block chain-based power Internet of Things terminal access method can improve the security and efficiency of authentication.

Description

technical field [0001] The invention relates to the field of Internet of Things node access authentication, in particular to a blockchain-based power Internet of Things terminal access method. Background technique [0002] The traditional terminal access authentication system is a centralized management structure. A large number of terminal authentication requests will lead to excessive consumption of network resources and computing resources of the central node, which can meet the real-time and flexibility requirements of the future Internet of Things. Therefore, it is urgent to study a A flexible, reliable, safe and efficient distributed authentication method and strategy. Blockchain is essentially a decentralized distributed ledger database, which has the characteristics of subject equality, openness and transparency, secure communication, difficulty in tampering and multi-party consensus, and has been more and more widely used in finance, logistics, energy and other fiel...
