detailed description

Before proceeding with the description of the specific embodiments, in order to more clearly express the content discussed, first define some very important concepts.

Trading: The essence of a transaction is a relational data structure that contains information about the value transfer of the trading participants. These transaction information is called the accounting ledger. The transaction needs to go through three creation, verification, and writing blockchains. The transaction must be digitally signed to ensure the legality of the transaction.

Block: All transaction information is stored in the block, and a transaction information is a record, which is stored as a separate record in the blockchain. The block consists of a block header and a data part. The block header field contains various characteristics of the block itself, such as the previous block information, the merkle value, and the timestamp. The block header hash value and block height are the two most important indicators for identifying the block. The block primary identifier is its cryptographic hash value, a digital fingerprint obtained by performing a second hash calculation on the block header by the SHA algorithm. The resulting 32-byte hash value is called the block hash value, or the block header hash value, and only the block header is used for calculation. The block hash value can uniquely and unambiguously identify a block, and any node can independently obtain the block hash value by simply hashing the block header.

Blockchain: A data structure in which blocks are chained in an orderly fashion. A blockchain is like a vertical stack, with the first block being the first block at the bottom of the stack, and each block is then placed on top of the other blocks. When a block is written to a blockchain, it will never change and is backed up to another blockchain server.

Embodiment: Referring to FIG. 1 , a trusted power network transaction platform based on blockchain technology can perform secure circuit network transactions with full trust, including: (1) blockchain database node module, The blockchain database holds a copy of the power transaction database at multiple nodes; (2) a block module, the blockchain database is divided into a plurality of blocks related to power transactions, each block containing transaction details, including the seller, Buyer, price, contract terms, real-time information on random fluctuations of power supply, topology of power grid and property rights subject; (3) encryption and authentication module, by sharing common transaction details and two or more The unique signature and merge encryption of the party obtains the whole network authentication, and the transaction is confirmed by encrypting and verifying the identity of each party of the photovoltaic power transaction, thereby ensuring that the “false” transaction cannot be added to the blockchain without obtaining the permission of the relevant party. When a transaction joins a blockchain, it runs a complex "hash" algorithm based on transaction data, the identity of the parties to the transaction, and historical transaction results. The current state of the blockchain is based on historical transactions to ensure that malicious attackers cannot change historical transaction records. If the transaction record is changed, it will affect the current value of the hash and does not match the other copies of the ledger; (4) Trust approval module, connected with the encrypted authentication module, including the hardware device trust approval sub-module, the software clear controllable approval sub-module a network application behavior trusted approval sub-module and a defense sub-module for establishing a trusted power network transaction system of the blockchain; (5) a decision module, under the mandatory trust mechanism, if the encryption records corresponding to all nodes are consistent, The transaction is valid and joins the historical trading chain; if the block is invalid, the node's "consensus" Change the information of the offending node, and join the historical transaction chain is operated under the premise of the block verification. The adoption of the mandatory trust mechanism is based on the complexity of the new energy transaction itself and the social environment and the existence of the “rational person”. A mechanism that must be adopted in blockchain algorithms due to misoperations and imperfections.

In the blockchain 1.0 phase, the blockchain realizes the registration of the power station operation and maintenance log blockchain and internal authorized access. In the 2.0 era, the realization of power plant management and operation based on big data, the automatic operation of the power station, so join the power station automatic management operation and maintenance blockchain module, for the automatic operation of the power station based on big data. In the 3.0 era, ID and economic account blockchain modules were added to the platform to configure traceable IDs and economic accounts for each component to achieve zero marginal cost generation, and sales revenue automatically offset operating costs.

A power trading platform that can be fully trusted needs to meet the following security objectives:

(1) Clear and controllable boundaries: Ensure that the power system blockchain has a clearly controllable network boundary to form a relatively closed and controllable environment.

(2) Trustworthy hardware devices: Ensure that all hardware devices involved in the blockchain are clear and trustworthy, including the entire process from procurement, use, maintenance to retirement, all of which are basic and controllable. The usage method and internal structure are clear and credible. The hardware usage and management procedures are clear and unified, and the hardware change process is clear and controllable.

(3) The software is clear and controllable: ensure that the group building system involved in the blockchain is clear and controllable, and the software source code Must be manageable, clear, and credible. All software must undergo strict security assessment before going online. Software updates and upgrades must be performed after strict security testing.

(4) Trustworthiness of network applications and behaviors: Ensure that applications and behaviors within the network are monitorable, measurable, and abnormal behaviors can be managed, including the credibility of user identities, the credibility of network behavior, and the integration of business processes. The three levels of security objectives are to ensure that the identity of the initiators of all network applications and behaviors is credible, the behavior itself is credible, and the serialized sequence of business operations is compliant.

(5) From the perspective of multiple lines of defense, build a closed-loop defense model, from the establishment of trusted blockchains to monitoring, and then to auditing and self-healing. The so-called establishment is to form a credible root, build clear and clear boundaries, physical security reinforcement of hardware devices to improve their reliability, security assessment and security reinforcement of software systems to prevent security threats caused by their own security vulnerabilities, so-called monitoring It is the monitoring of the trusted environment. It needs to monitor the overall operation of the system in real time and discover the security threat organization. The so-called audit is to audit all user operations and behaviors in the blockchain to ensure trusted execution rights. The user's behavior is compliant, the so-called self-healing recovery, so that the system returns to normal operation and provide services in the shortest time.

To this end, the physical frame-based data frame management technology is used to monitor whether the source address of the data frame is a trusted address in real time, and ensure that the devices communicating in the trusted blockchain area are known and controllable, thereby forming a clear The blockchain boundary further divides multiple trusted nodes and link regions based on the blockchain boundary implementation. Separate by the security switch, each security switch strictly controls the communication in the blockchain where it is located, ensuring that any newly requested device is strictly controlled by the security switch to ensure the data is unidirectionally transmitted. Or authenticated two-way data transmission to prevent other malicious data from entering the blockchain.

Create a "safe initial state" and "trusted process list" of the system, which only allows the core processes of the necessary processes and blockchains to be run, extract process information, and form a trusted representation through operations, and store them in the "trusted process list". Run the monitoring program in the background, intercept the process to obtain the execution permission of the system in real time, and perform the trust verification on the blockchain process, including the credibility of the user identity and user behavior. The capricious audit, the audit uses the WarShall algorithm to calculate the reachability matrix, and the matrix is stored in the compliance rule base, so after multiple accumulations and learning, a common compliance rule base is formed, and the actual reachable matrix is ascertained during the audit. By comparing with the information in the rule base, the trustworthiness of the user operation can be determined, and the trustworthiness can be quantified, the user's credit account record can be established, and the user can be prevented from further warning that the user no longer has a violation operation.

The present invention has been described with reference to the specific illustrative embodiments, and is not limited by the scope of the appended claims. It will be appreciated by those skilled in the art that the embodiments of the invention can be modified and modified without departing from the scope and spirit of the invention.
