In the related technology, although the generators in the power plant can be networked through the internet of things technology, the generation data of the generators can be uniformly read for management, and the efficiency and accuracy of the generated energy statistics are improved, the scheme still has the problems that the data are falsified and related departments are difficult to manage in a penetrating manner.
Based on this, this specification proposes one kind and uses the thing networking to carry out the networking with power generation facility, docks to the block chain in to deposit the technical scheme that proves through the generated energy data of block chain to the power generation facility of networking.
When the intelligent power generation system is realized, the power generation equipment carrying the Internet of things chip and the block chain can be regarded as part of the intelligent power grid, and the power generation equipment can claim decentralized identities in the block chain, so that the power generation equipment signs the generated energy data through the carried Internet of things chip by using the corresponding decentralized identities and then sends the signed generated energy data to the block chain for storage.

in addition, because the related operation of the block chain in the technical scheme is completed by using the chip of the internet of things, the original chip of the internet of things in the industrial internet can be obviously reused, and the landing cost of the scheme is reduced.
The present specification is described below with reference to specific embodiments and specific application scenarios.
Referring to fig. 1, fig. 1 is a flowchart illustrating a block chain-based power generation data management method according to an embodiment of the present disclosure, where the method may be applied to a smart grid system; the intelligent power grid system comprises power generation equipment based on the Internet of things and a block chain in butt joint with the Internet of things; the method may comprise the steps of:
s101, establishing a decentralized identity for the power generation equipment, managing files of the decentralized identity by the block chain, and binding the decentralized identity with an Internet of things chip in the corresponding power generation equipment;
s102, the power generation equipment uses the decentralized identity to sign own generated energy data through an internet of things chip of the power generation equipment;
and S103, sending the signed generated energy data to the block chain for evidence storage.
The block chain can comprise any form of block chain. The block chain technology, also called as distributed account book technology, is a technology in which a plurality of computing devices participate in accounting together and maintain a complete distributed database together; in general, blockchains have the characteristics of decentralization, public transparency, participation in database records by each computing device, and rapid data synchronization between computing devices. Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on. In general, various types of blockchain properties may differ, and thus may be used to meet different technical requirements; for example, if the highest degree of decentralization is desired, a public chain may be selected; federation chains, etc., may be selected if desired to compromise decentralization and performance. In implementation, if the blockchain is in a form of a alliance chain, the blockchain nodes constituting the blockchain can be provided by various types of entities such as relevant management departments, power plants, cloud service providers and the like, so as to ensure that the block chain billing right is relatively fair and reasonable; for another example, if the block chain is in the form of a programmable block chain, a general intelligent contract can be used to construct related functions, and higher programming flexibility is achieved; it can be seen that various types of blockchains are advantageous, and those skilled in the art can select the type of blockchain according to specific requirements without limiting the specific type of blockchain in the present specification.
It can be understood that the above block chain may interact with the outside through a block chain as a Service (BaaS) platform. Generally, BaaS platforms can provide flexible and customizable blockchain services to client-side computing devices connected to BaaS platforms by providing pre-written applications for activities that occur on the blockchain (such as subscription and notification, user authentication, database management, and remote updates). For example, in one example, if a server for data presentation needs to perform data communication with a blockchain, the BaaS platform may provide a service application such as MQ (Message Queue); the server connected with the BaaS platform and used for data publicity can subscribe an intelligent contract deployed on a certain block chain in a block chain system connected with the BaaS platform and trigger a contract event generated on the block chain after execution; and the BaaS platform can monitor the event generated on the block chain after the intelligent contract is triggered to execute, and then based on the software related to MQ service, the contract event is added to the message queue in the form of notification message, so that the service end which subscribes to the message queue and is used for data presentation can obtain the notification related to the contract event.
The smart grid can be a network form combining a computer network and a power network; it is generally believed that the intellectualization of a smart grid, i.e., a power grid, can be a novel power grid that is established on the basis of an integrated, high-speed two-way communication network and achieves the goals of reliability, safety, economy, efficiency, environmental friendliness, and safety in use of the power grid through the application of sensing and measuring techniques, devices, control methods, and decision support system techniques, and its main properties include self-healing, energizing and protecting users, resisting attacks, providing power quality that meets the needs of users, allowing access to various different forms of power generation, starting the power market, and optimizing efficient operation of assets, etc.
The Internet of Things (Internet of Things, IoT for short) can acquire any object or process needing monitoring, connection and interaction in real time through various devices and technologies such as various information sensors, radio frequency identification technologies, global positioning systems, infrared sensors and laser scanners, acquire various required information such as sound, light, heat, electricity, mechanics, chemistry, biology and position of the object or process, realize ubiquitous connection of the object and the person through various possible network accesses, and realize intelligent sensing, identification and management of the object and the process. Generally, the internet of things is considered as an information carrier based on the internet, a traditional telecommunication network and the like, and common physical objects which can be independently addressed can form an interconnected network.
In the art, Decentralized IDentity (DID) is generally understood as an IDentity authentication mechanism that may contain identification and document, with global uniqueness, high availability resolvability and encryption verifiability. A decentralized identity may be said to be associated with a blockchain if the decentralized identity depends on a blockchain implementation. In implementation, a typical decentralized identity may be represented by the following character string:
did:example:123123123123abcabcabc
wherein, the did part is a system identification for indicating that the character string is a decentralized identity; the example part is a DID method identifier used for indicating the method on the block chain on which DID specifically depends; the 123123123123abcabc part is an identifier specified in the DID method, typically corresponding to a pair of public and private keys held by the individual whose identity corresponds to. The decentralized identity document may include an identity public key corresponding to the DID, a corresponding encryption algorithm, and other information, and may be used to verify the decentralized identity. For example, assuming that a user, zhang san sends a piece of information, which carries a signature of a decentralized identity and a DID identifier, other users can check the validity of the decentralized identity signature only by finding the decentralized identity public key of zhang san from the block chain according to the DID identifier, and if the check is passed, the sender of the information can be proved to be a person who holds the private key of zhang san of the user, that is, zhang san self.
It will of course be appreciated that there is no essential difference from person to thing in terms of blockchain, and that decentralized identities can be assigned to either natural persons or devices or organizations; in this specification, a decentralized identity may be assigned to a power plant and bound to an internet of things chip in the corresponding power plant.
In this specification, a decentralized identity may be first created for the power generation device, a file of the decentralized identity is managed by the blockchain, and the decentralized identity is bound to an internet of things chip in the corresponding power generation device; specifically, the behavior of creating the decentralized identity can be initiated by an internet of things chip of the power generation equipment using the decentralized identity, and can also be initiated by a management server side in batch; for example, assuming that the power plant a has a strong embedded development capability, a program for initiating the creation of a decentralized identity may be developed for the internet of things chip of each power generation device, and each internet of things chip may complete a related task by itself; and if the embedded development capability of the power plant B is weaker, special volume production personnel can apply for decentralized identities in batches, and the identities are respectively bound to the Internet of things chips and then the Internet of things chips are issued to the power generation equipment.
Generally, if the behavior of creating the decentralized identity is initiated by an internet of things chip of the power generation equipment using the decentralized identity, a private key in a public and private key pair is not exposed in the whole process, so that the security is higher, but the requirements on the program design, the performance and the like of the internet of things chip are higher; if the behavior of creating the decentralized identity is initiated in batch by the management server, the workload of creating the decentralized identity can be saved, and the requirements on the performance of the internet of things chip and software development are low.
Therefore, the executing subject of the foregoing decentralized identity establishment procedure is not limited in this specification, and those skilled in the art can make trade-off decisions according to specific business scenarios and requirements.
In one embodiment, the above process of creating a decentralized identity may be implemented according to characteristic information of the power generation equipment. Specifically, the creating a decentralized identity for the power generation device includes: and generating a public and private key pair according to the characteristic information of the power generation equipment, and sending a decentralized identity application request signed by a private key in the public and private key pair and a public key in the public and private key pair to the block chain, so that the block chain creates a decentralized identity corresponding to the public key under the condition of verifying that the signature of the decentralized identity application request passes. For example, the serial number of the power generation equipment may be used as a parameter when generating a public-private key pair after mathematical transformation such as hashing, and the like.
Through the scheme, the public key for generating the decentralized identity can be associated with the characteristic information of the power generation equipment, so that the decentralized identity can be generated in batch by using a uniform algorithm, the convenience of management is improved, and the corresponding power generation equipment can be traced backwards according to the decentralized identity.
In one embodiment shown, a private key in the public and private key pair may be managed by a trusted execution environment in the chip of the internet of things; specifically, the internet of things chip is loaded with a trusted execution environment; the generating of the public and private key pair according to the characteristic information of the power generation equipment may include: generating a public and private key pair in a trusted execution environment carried in the chip of the internet of things by the chip of the internet of things in the power generation equipment according to the characteristic information of the power generation equipment, and exposing a calling interface of a private key in the public and private key pair and a public key in the public and private key pair to the outside of the trusted execution environment; the process of binding the decentralized identity with the internet of things chip in the corresponding power generation device may specifically include: and the Internet of things chip in the power generation equipment receives the identifier of the decentralized identity returned by the block chain and binds the identifier of the decentralized identity with a calling interface of a private key in the public and private key pair.
Referring to fig. 2, fig. 2 is a diagram illustrating an example of a structure of an internet of things chip with an embedded trusted execution environment; the chip of the internet of things can comprise a main control module, a network module and the trusted execution environment, the private key can be stored in the trusted execution environment, and a private key calling interface used for calling the private key is opened to the outside. For executable codes outside the trusted execution environment, although the private key can be called through the private key calling interface to complete operations such as signature, the private key itself is not directly exposed to the outside.
Therefore, by applying the scheme, the security of the private key can be improved, and the credibility of the signature given by the private key is further improved.
In this specification, the power generation equipment may use the decentralized identity to sign its own power generation amount data through its own internet of things chip; the signature can be a signature containing data integrity verification information, or a signature purely used for verifying a source and not containing the integrity verification information; if the signature needs to include data integrity verification information, a person skilled in the art can generate summary information of the power generation amount data by using a summary algorithm, and then encrypt the summary information by using the private key to obtain a signature capable of being used for verifying the integrity of the power generation amount data.
It is understood that, of course, what abstract algorithm is specifically adopted in the above process, such as SHA-256, MD5, SM-3, etc., and the present specification is not necessarily limited in detail.
In this specification, finally, the signed power generation amount data may be transmitted to the block chain for verification. Specifically, a transaction including the signed power generation amount data may be constructed and sent to a blockchain, so that the blockchain verifies the signed power generation amount data carried in the transaction in a distributed ledger of the blockchain; it is understood that, in order to save the storage space on the chain, the signed power generation amount data may be stored in a down-chain database interfacing with the blockchain, and a summary of the signed power generation amount data and a storage address in the down-chain database may be stored in a distributed book of the blockchain. The method specifically adopts a direct evidence storage mode or an indirect evidence storage mode, the specification is not limited in detail, and a person skilled in the art can determine and implement the method according to specific requirements.
It can be understood that the content of the block chain stored with the certificate may include the name, model, number and other characteristic information of the corresponding power generation equipment in addition to the signed power generation data, so as to facilitate later management and monitoring.
In one embodiment, the signed power generation data may be classified and counted according to the corresponding decentralized identity. Specifically, when the electricity generation amount data is signed, the signed electricity generation amount data may be sent to the block chain, so that the block chain stores the signed electricity generation amount data in the distributed account book, and an address of the signed electricity generation amount data is added to an index of identification retrieval based on a decentralized identity; then, the corresponding card storage address corresponding to each decentralized identity to be counted can be searched in the index, corresponding power generation amount data is retrieved from the distributed account book of the block chain according to the searched card storage address, and the retrieved power generation amount data is classified and counted according to the decentralized identity.
