And verifying the signature of the issuing mechanism of the identity certificate of the user to be verified by the verification user, and decrypting and mechanically using the private key to verify the identity by using the template. And comparing the identity information of the user to be verified with the chain, and confirming the identity of the user to be verified by adopting a public and private key pair matching method after the identity information is correct, so that high-reliability identity authentication is realized.
In the above embodiment, the registration admission module binds the user identity information with the public key to generate the identity credential based on the multi-party endorsement advantage of the block chain, which ensures that the user registration information is trustable and traceable, allows the user information to have higher credibility, and can avoid the problems of unclear metering, fraudulent supplementation and the like caused by inaccurate main registration and verification of the user compared with the conventional method.
In the embodiment of the invention, a front-end service system is used as a unique data source, monthly electric quantity data, internet-surfing electricity price, subsidy electricity price and subsidy data of rural happy users related to distributed photovoltaic power generation in a province or city region are collected through system integration, and the data of a service platform is consistent with the data of the service system in real time. Each item of original data is stored in a data storage module by adopting a block chain, so that the traceability of the data on the chain is ensured.
In some embodiments, after establishing the bilateral order according to the confirmed contract, further comprising: and generating a transaction voucher, and updating the consumption vouchers of the seller and the buyer according to the transaction voucher. Wherein the transaction credentials include: seller signature, buyer signature, transaction time, electricity quantity, electricity price and channel.
After the bilateral transaction is completed, the power consumption of the seller and the power consumption of the buyer are changed, the consumption certificates of the seller and the consumption certificates of the buyer are updated in real time according to the transaction certificate, and the full life cycle traceability management of the power consumption certificates is realized.
The system for distributed power supply management is set based on the block chain, user authentication admission, consumption certificate issuing and transaction are respectively completed through the registration admission module, the consumption certificate module and the contract gateway module, information self-verification, transmission and management are realized through each node through distributed operation, operation on a transaction chain is realized, the transaction transparency and efficiency are guaranteed, the consensus efficiency is improved, meanwhile, the data cannot be counterfeited or tampered, and the data safety is improved.
In a specific application embodiment, a power grid enterprise, a distributed photovoltaic power generation management department (rural happiness department) and a income transfer mechanism are used as nodes on a chain to participate in data calculation chaining and store all accounts of the whole chain, and distributed photovoltaic power generation users (residents) and government supervision departments are used as witness nodes to supervise the data on the chain and fully exert the characteristics of tamper resistance, traceability and high reliability of a block chain technology. Because the system for distributed power supply management in the embodiment of the present invention is set up based on the block chain, the system may not be able to communicate due to network fluctuation, and the master node generally has two error situations: the main node does not respond due to failure; the main node is a Byzantine node and maliciously tampers with the message sent by the client. The embodiment of the present disclosure dynamically adjusts the master node based on a Dynamic Practical Byzantine Fault Tolerance (DPBFT) algorithm.
The DPBFT algorithm sets a scoring mechanism with an initial score of 0 for each node, a first unresponsive master node withholding 5 points, and a second rogue master node withholding 10 points. And if the node is honest, adding 1 point to the node if the consensus process is successfully completed. When all the node scores are the same, randomly extracting one node as a main node; and when the scores are different, selecting the master node with the highest score.
In the specific embodiment, a power grid enterprise, a distributed photovoltaic power generation management department (rural happiness department), a income transfer institution distributed photovoltaic power generation user (resident) and a government supervision department are used as nodes. The specific host node adjustment process is as follows:
all the replica nodes participate in voting, and one main node is selected. The initial score of each node is 0, the probability that each node is selected as the master node is equal, and the voting determines the master node. Subsequently selecting a main node to preferentially extract from the nodes with the highest scores;
after the system sends a request for selecting the master node, the states of the master node are classified into 3 types: the main node sends an error message, the main node does not respond, and the main node is honest;
if the master node does not respond, 5 points are deducted from the node and a view switching protocol is triggered, wherein the view switching message format is 'Viewchange, n, C, P, i';
if the master node sends an error message, namely after receiving a request, the master node broadcasts the error message to other slave nodes, the format of the broadcast message is < < Pre, V, n, d >, M >, an error serial number is maliciously distributed, and other slave nodes cannot pass verification, 10 points are deducted from the master node, and a view switching protocol is entered, and a view switching message is sent;
if the main node is an honest node and successfully completes a consensus process, adding 1 point to each node in the consensus process, and verifying, recording and writing the message confirmed by each node into a block;
and selecting the node with the highest score as the main node according to the scores of all the nodes.
In order to prevent the honest consensus nodes from changing or going down after the system normally operates, new main nodes are periodically reselected according to the main node adjusting process, and are selected according to the real-time node scores every time, so that the probability that the malicious nodes become the main nodes is reduced. In a specific application process, a malicious cheating subsidy behavior of an enterprise or a user in the power transaction process can be restrained.
