Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a blockchain-based power transaction method according to an exemplary embodiment, where the blockchain-based power transaction method is used in a blockchain platform, as shown in fig. 1, and includes the following steps.
S11, the blockchain platform obtains a data evidence storing request sent by the electric power transaction main body, wherein the data evidence storing request comprises: the source data comprises power data to be transacted, the digital signature and the CA authentication information.
Wherein, the electric power transaction body can include: electricity buyers and electricity sellers. The power purchaser may be an electronic device owned by a power consumption organization or an electronic device owned by an individual, and the power seller may be an electronic device owned by an organization having a power selling right or an electronic device owned by an individual.
The electric power transaction main body can be in communication connection with the block chain platform through a public network or an exclusive network, and of course, other devices can be in communication connection with the block chain platform besides the electric power transaction main body, such as: a supervisor device.
Optionally, the source data may include: power data to be traded. The power data may include: an amount of electricity; further, the power data may further include: electricity price; further, the power data may further include: voltage, etc.
Optionally, the electricity price in the power data may be a fixed electricity price or an electricity price that changes with time.
Of course, the source data may also include identification information of the power transaction subject, and the like, and the present invention is not limited herein.
Optionally, the source data may be encrypted data obtained by encrypting the public key of the blockchain platform by the power transaction subject, and after receiving the encrypted source data, the blockchain platform may decrypt the encrypted source data by using a private key of the blockchain platform to obtain the source data.
Of course, the power transaction main body may also use other encryption methods to encrypt the source data, and correspondingly, the blockchain platform may use a corresponding decryption method to decrypt the source data.
The digital signature (also called public key digital signature) is a section of digital string which can be generated only by the sender of the information and cannot be forged by others, and the section of digital string is also a valid proof for the authenticity of the information sent by the sender of the information. It is a method for authenticating digital information that is similar to a common physical signature written on paper, but is implemented using techniques in the field of public key cryptography. A set of digital signatures typically defines two complementary operations, one for signing and the other for verification. The digital signature is an application of asymmetric key encryption technology and digital digest technology.
CA authentication, i.e., electronic authentication service, refers to an activity of providing authenticity and reliability verification for each party related to an electronic signature. A Certificate Authority (CA), i.e. an Authority that issues digital signatures, is an Authority responsible for issuing and managing digital signatures, and is a trusted third party in e-commerce transactions, which assumes responsibility for validity checking of public keys in a public key infrastructure. The CA authentication information in the data certification request may be authentication information that the electric power transaction body previously obtained from a certificate issuing authority.
Optionally, the digital signature and/or the CA authentication information in the data authentication request may be encrypted information to ensure the security of the information. For example: the electric power transaction main body encrypts the digital signature and/or the CA authentication information through a first private key, and the block chain platform decrypts by using a first public key corresponding to the first private key. The first private key and the first public key may be a public-private key pair of the power transaction body. The following steps are repeated: the electric power transaction main body encrypts the digital signature and/or the CA authentication information through the second public key, and the block chain platform decrypts by using a second private key corresponding to the second public key. The second private key and the second public key may be a public-private key pair of the blockchain platform.
And S12, the block chain platform verifies the digital signature and the CA authentication information in the data certificate storage request, and if the verification is passed, the source data is uploaded to the block chain for certificate storage.
Optionally, the blockchain platform may send the CA certification information to a certificate authority to verify the CA certification information. Optionally, the blockchain platform may verify the digital signature through a public and private key pair.
Optionally, the blockchain platform may decrypt the encrypted source data, and then upload the decrypted source data to the blockchain for storage. In other embodiments, the blockchain platform may decrypt the encrypted source data and then upload the hash value of the decrypted source data to the blockchain for verification.
And S13, executing the intelligent contract according to the source data in the block chain by the block chain platform, and uploading the transaction result to the block chain for evidence storage.
A Smart Contract (Smart Contract) is a computer protocol intended to propagate, verify or execute contracts in an informative manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
Optionally, the method can provide intelligent contract customized service for each transaction subject according to transaction rules, meet personalized requirements of transactions, and realize transparent and traceable disclosure of transaction settlement. In practical application, each market main body can customize an intelligent contract on a block chain platform according to business requirements, so that the transaction forms of different business requirements are realized, the business realization process of marketized transaction is reconstructed, participation of third-party main bodies is reduced, and the openness and transparency of electric power transaction are improved. The method can develop a series of intelligent contracts in a customized manner according to individual requirements provided by a transaction main body and different transaction rules, and complete deployment operation on a chain, wherein the customized requirements comprise the customized requirements of transaction intelligent contracts, user access control contracts and the like. The customized intelligent contract needs to be completely familiar with transaction business, and algorithm compilation is completed according to business requirements, and meanwhile, the operation efficiency is guaranteed.
It will be appreciated that since the source data includes power data to be traded, the present disclosure may execute smart contracts with the power data, such as: the intelligent contract is executed by marking ownership of 1000 degrees of electricity as an electricity purchaser and ownership of an amount of money as an electricity seller.
After the transaction result is uploaded to the block chain for evidence storage, the invention is beneficial to follow-up tracking and query of the electric power transaction and simultaneously proves the compliance of the electric power transaction.
The block chain-based power transaction method provided by the embodiment of the invention can verify the digital signature and CA authentication information of a power transaction main body, and upload source data to the block chain for storing the certificate and executing an intelligent contract after the verification is passed. The invention effectively ensures the safety of electric power transaction.

When the electricity transaction subject is an individual, the subject information of the electricity transaction subject may include: at least one of name, identification number and account book information.
And S02, the blockchain platform verifies the identity registration request, if the verification is passed, a public and private key pair is generated for the electric power transaction main body, and the public and private key pair is sent to the electric power transaction main body, so that the electric power transaction main body generates a digital signature by using the public and private key pair.
Optionally, the verification process for the CA authentication information may be the same as the verification process for the CA authentication information in the embodiment shown in fig. 1, and is not described again. The verification process of the subject information of the electric power transaction subject may be as follows: and sending the subject information of the power transaction subject to the equipment of the organization with the subject information verification authority, and obtaining the verification result returned by the equipment. Of course, the device of the institution having the principal information verification authority may be connected to the blockchain platform, and verify the principal information of the electric power transaction principal on the blockchain platform.
And the public and private key pair generated by the block chain platform for the electric power transaction main body is the public and private key pair of the electric power transaction main body.

and S14, the blockchain platform sends the electronic contract generated based on the source data and the subject information of the electric power transaction subject to the electric power buyer and the electric power seller.
Specifically, the blockchain platform may fill the power data (such as the amount of electricity and the price of electricity) to be traded, the name of the power buyer and the name of the power seller into a preset contract template to generate the electronic contract. Of course, the blockchain platform may also fill more other information into the contract template, such as the total transaction amount.
Optionally, the sending of the electronic contract to the electric power purchaser and the electric power seller may specifically be: and sending the electronic contract to the block chain network. Thus, the electricity buyer and the electricity seller can see the electronic contract from the blockchain network.
And S15, after the electric power buyer and the electric power seller sign the electronic contract, the block chain platform uploads the signed electronic contract to the block chain for storage.
Optionally, the electricity purchaser and the electricity seller may sign the electronic contract through the blockchain network.
After the signed electronic contract is uploaded to a block chain for storage, the compliance of the transaction can be reflected, and the subsequent examination is facilitated.
In other embodiments, step S13 in the embodiment shown in fig. 3 may specifically include:
and the block chain platform executes the intelligent contract to complete the electric power transaction based on the signed electronic contract, and uploads the transaction result of the electric power transaction to the block chain for evidence storage.
As shown in fig. 4, another block chain-based power transaction method provided in the embodiment of the present invention, relative to the embodiment shown in fig. 1, may further include:
and S16, the blockchain platform receives an access request sent by the data accessor for the target data uploaded to the blockchain.
Wherein the data accessor may be a device owned by an individual or organization that needs to access the data in the blockchain, such as: a regulatory agency's equipment, etc.
Alternatively, the target data may be any data in the block chain, such as the source data, the electronic contract, the statistical result of the source data, and the like.
S17, the block chain platform determines whether the data access party has the authority of accessing the target data according to the access request, and if so, the target data in the block chain is sent to the data access party.
Optionally, the present invention may set different permissions for different data accessing parties respectively, so that the data accessing party meeting the requirements may access the target data. Of course, the invention can also set the level for the target data, and the authority required by different levels can be different.
Optionally, a plurality of attribute sets are stored in the blockchain platform, where each attribute set includes at least one attribute information, different attribute sets correspond to different access permissions, and the access request carries the attribute information of the data access party, and step S17 may specifically include:
and the block chain platform determines whether the attribute information of the data access party carried by the access request is consistent with the attribute information in the attribute set corresponding to the target authority, if so, the data access party is determined to have the authority of accessing the target data, otherwise, the data access party is determined not to have the authority of accessing the target data, wherein the target authority is the authority of accessing the target data.
The attribute information of the data access party may include: the organization attribute of the organization corresponding to the data access party or the personal attribute of the individual corresponding to the data access party. Wherein the mechanism attributes may include: enterprise type of organization, organization affiliated unit, organization address, organization scale, etc. The personal attributes may include: age, sex, affiliated units, etc. of the individual.

The attribute set of the data access party can be set according to the requirements and the authority of different data access parties. When data needs to be accessed, the data access party uploads the attribute set and the digital signature to the blockchain platform, the blockchain platform judges whether the data access party has the authority to access the data or not according to the digital signature and the attribute set, and the data access party can check the specific data after the judgment is passed, so that the access control of a user is realized.
Optionally, the attribute may be encrypted based on a ciphertext policy, and the specific scheme is as follows: in a ciphertext-policy-based attribute-based encryption (CP-ABE) algorithm, a ciphertext corresponds to an access control structure, and a key corresponds to an attribute set, so that decryption can be successful only when the attribute set of a data access party can satisfy the corresponding access control structure.
After the attribute encryption algorithm based on the ciphertext strategy is used, access strategies can be formulated in advance according to various data access parties, and different attribute sets can be configured. When the attribute encryption algorithm based on the ciphertext strategy is called, whether the request of the data access party is legal or not can be quickly judged, so that the fineness of authority management is improved, and the safety protection level of source data is improved.
