If the two checks pass, the thing networking terminal is judged to be safe and credible when being accessed into the block chain network, and the authorized thing networking terminal can upload terminal acquisition data to the block chain. Then, the blockchain consensus node sends an authorization passing message to the terminal and the body of the Internet of thingsAnd an authorization module.
If the random check fails, the fact that the terminal of the Internet of things is accessed to the block chain network is determined to be unsafe, and the request that the terminal of the Internet of things uploads the data collected by the terminal to the block chain is rejected.
Step four: and removing the identity authorization module, and enabling the Internet of things terminal to normally upload terminal acquisition data to the block chain.
The internet of things terminal and the identity authorization module receive the authorization passing message, the identity authorization module can remove the identity authorization module by using light flicker prompting, and the internet of things terminal can normally upload terminal acquisition data to the block chain from the moment.
Step five: after the internet of things terminal is disconnected with the block chain network and reconnected, when the secondary data uploading authorization fails, the identity authorization module needs to be inserted again for authorization again.
And (3) the internet of things terminal and the block chain network are disconnected due to any reason (including network link fluctuation, block chain link point halt and internet of things terminal halt), after the internet of things terminal and the block chain network are connected and reconnected successfully, authorization for uploading data to the block chain by the internet of things terminal at the last time fails, the internet of things terminal identity authorization operation needs to be carried out again in the steps from one step to the fourth step, and then the internet of things terminal side can continue to upload the data to the block chain network.
