example

[0077] Simulate user A to initiate a transaction to user B, transaction sender A, transaction receiver B, and the transaction is verified by the entire network nodes.

[0078] First, if figure 2 As shown, A reads and inputs its identity information through MAC, uses "MAC address + password" as a private key, and the public key corresponding to the private key is generated by an elliptic curve, and then uses the HASH256 hash algorithm to convert the public key into an identity Address, and uploaded to the identity registration chain, A completes the identity registration; then, if image 3 As shown, A uses the HASH256 hash algorithm to hash the transaction information, generates a hash summary, which is recorded as Y1, and encrypts it with a private key to generate a digital signature; A initiates a transaction, and sends the signature, hash summary Y1 and public The key is sent to the whole network; if Figure 4 As shown, the nodes of the whole network jointly verify the tr...

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. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] As the third industrial revolution and a new direction for the development of future social interconnection technology, the Internet of Things has brought great changes to people's production and life after the Internet. The development and application of the Internet of Things technology has achieved remarkable results in recent years. A large number of sensors and equipment are connected and combined with the Internet to realize intelligent management and operation. At the same time, as the scale of the Internet of Things continues to expand, the security and privacy issues of the Internet of Things have become one of the threats faced by the I...
