Method for registration and verification of Internet of Things identity based on blockchain

Abstract

The invention belongs to the technical field of blockchains, and discloses a method for registration and verification of an Internet of Things identity based on a blockchain. The method comprises thefollowing steps: in an Internet of Things transaction, a sender reads and enters his identity information through a MAC, completes identity registration, and deposits identity information into an identity registration chain; the sender hashes the transaction information, generates a hash digest, records the hash digest as Y1, and encrypts the same with a private key to generate a digital signature; the sender initiates the transaction, and sends the signature, the hash digest Y1, and the corresponding public key to the whole network; nodes of the whole network verify the transaction information; and all nodes further determine whether the sender has been registered, and upload the transaction to the transaction chain if passing the two-factor verification. The method enables the identity of the transaction on the Internet of Things to be proved to be correct without revealing the identity of the trader through the blockchain technology, thereby avoiding the leakage of the trader's identity information during the transaction.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method for registering and verifying identity of the Internet of Things based on block chains.
