Generally, the storage management device of the power business data can be a power internet of things system.
The following description will be given taking a storage management device of power service data as an example of a main body that performs a storage management method of power service data. Referring to fig. 1, the method for storing and managing power service data specifically includes:
s110, appointing a third party to send a data label to a corresponding intelligent electric meter and a data management node in advance, sending a data encryption key to the intelligent electric meter in advance by the data management node, and reserving a corresponding data decryption key.
The storage management method for the power service data aims to select the corresponding service data storage mode according to the data type of the service data, so that the safety of service data storage and extraction is improved adaptively, the efficiency of data extraction is guaranteed, and the operation of the power internet of things is optimized.
Specifically, referring to fig. 2, in the electric power internet of things system, each smart meter 11 is in signal connection with a public node 12 and a private node 13, respectively, and is used for storing service data of the smart meter 11. The public nodes 12 and the private nodes 13 are provided in a plurality, and when the smart meter 11 stores the service data, the service data is stored to the plurality of public nodes 12 or the plurality of private nodes 13 according to the data type of the service data, so that the service data is stored. Correspondingly, the data management node 14 is in signal connection with the public node 12 and the private node 13, and is used for extracting service data stored in the public node 12 and the private node 13 to perform processing on related services of the power internet of things. The intelligent electric meter 11 is arranged corresponding to each power consumption unit, and collects and stores relevant service data generated in the household power consumption process. The public node 12 and the private node 13 are used for storing service data corresponding to the storage attribute, the public node 12 stores the service data of the public attribute, and the private node 13 stores the service data of the private attribute. The public node 12 can directly return corresponding service data according to the data request of the data management node 14 without verifying the identity of the data management node, so that the data management node can rapidly extract related service data for service processing, the processing efficiency of the service data is improved, and the operation of the electric power internet of things system is optimized. The private node 13 verifies the validity of the data management node identity according to the data request of the data management node 14, so as to ensure the security of the data extraction process and avoid the situation that the service data is stolen by an illegal node. And one end of the corresponding data management node performs related service processing according to the extracted service data so as to realize service operation processing of the power Internet of things system. In addition, the electric power internet of things system further comprises a trusted designated third party 15, the designated third party 15 is used as a server for generating data labels, the data labels are used for generating the data labels of the intelligent electric meters, the data labels are respectively sent to the intelligent electric meters 11 and the data management node 14, and the intelligent electric meters 11 are added to correspondingly add the data labels when business data are stored in the private nodes. Correspondingly, when the data management node 14 requests the private node for the service data, the data tag also needs to be attached to the request information, so that the private node can determine the validity of the data management node based on the data tag comparison, thereby ensuring the security of the data extraction process. In addition, in order to further improve the security of data storage and extraction, the data management node 14 configures a data encryption key for the smart meter 11, wherein the data encryption key is used for encrypting the service data stored in the private node 13. The data management node 14 reserves a corresponding data decryption key to facilitate decryption of the traffic data extracted from the private node 13. The data is stored by encrypting the data, so that the difficulty of stealing the data can be increased, and the safety of data storage and extraction is further improved.
In one embodiment, a third party is designated to send a data tag to a corresponding smart meter and a data management node in advance, the data management node sends a data encryption key to the smart meter in advance, and after a corresponding data decryption key is reserved, the data management node updates the data encryption key to the corresponding smart meter every other key management period, and reserves the corresponding data decryption key. It can be understood that, by periodically updating the data encryption key and the data decryption key, the situation that the data encryption key and the data decryption key are easily broken, which causes the stealing and the leakage of the service data can be avoided. Therefore, the difficulty of stealing the service data is increased, the safety of data storage and extraction is improved, and the operation of the power internet of things is optimized.
In one embodiment, a third party is designated to send data tags to corresponding smart meters and data management nodes in advance, the data management nodes send data encryption keys to the smart meters in advance, and after corresponding data decryption keys are reserved, the third party is designated to update the data tags to the corresponding smart meters and the data management nodes every other tag management period. Similarly, in order to avoid that the data tag is cracked and forged, so that an illegal node can easily acquire service data stored by a private node, the embodiment of the application designates a third party to periodically update the data tag to the intelligent electric meter and the data management node, thereby increasing the difficulty of stealing the service data, improving the safety of data storage and extraction, and optimizing the operation of the power internet of things.
S120, the intelligent electric meter determines storage attributes of the service data based on the data type of the current service data, wherein the storage attributes comprise public attributes and private attributes, the service data are divided into a plurality of service data packets which are redundant mutually, and if the storage attributes of the service data are the public attributes, the service data packets are directly stored to all public nodes in a distributed mode; if the storage attribute of the service data is a private attribute, encrypting the service data packet by using the data encryption key, adding the data tag to the service data packet, and storing the service data packet to each private node in a distributed manner; the service data packet further comprises identification information of the intelligent ammeter and timestamp information corresponding to the service data.
Further, when the service data is stored, the smart meter determines the storage attribute of the current service data based on the data type of the service data. The storage attribute identifies the location where the service data needs to be stored. If the storage attribute of the current service data is a public attribute, the service data needs to be stored to a public node; and if the storage attribute of the current service data is a private attribute, the service data needs to be stored to a private node. It can be understood that the smart meter generates a lot of service data during the daily operation. The data types of the service data comprise user identity information, a home address, power consumption data, an electric meter operation log, safety monitoring data and the like, wherein part of the service data related to user privacy, such as the user identity information, the home address, the power consumption data and the like, is private, and in order to avoid data leakage and data stealing caused by network attack on the part of the service data, the part of the service data needs to be stored in a private node. And for part of service data with lower security requirements, the service data can be directly stored in the public node, and the subsequent data management node can directly extract the data when extracting the data, so that the efficiency of extracting and processing the part of service data is improved, and the processing efficiency of related services is optimized.
Before that, the data management node pre-constructs a mapping relation between each data type and the corresponding storage attribute, and issues the mapping relation to the intelligent electric meter; correspondingly, when the intelligent electric meter determines the storage attribute of the service data based on the data type of the current service data, the intelligent electric meter queries the mapping relation based on the data type of the service data to determine the storage attribute of the service data. And the data management node manages the storage attribute to which each data type belongs through the mapping relation, and configures the private attribute for each data type if the security requirement is high and the data needs to be stored in the private node according to the actual storage requirement of the service data of each data type. On the contrary, if the requirement on the safety of the data type service data is not high, in order to facilitate the subsequent efficient extraction and processing of the part of service data, the part of service data needs to be stored to the public node, and then the public attribute is configured for the data type.
In one embodiment, the data management node modifies the corresponding mapping relation according to a real-time service data storage requirement, and updates the corresponding mapping relation to the smart meter. It can be understood that, according to the real-time service data storage requirement, if the storage attribute of the service data of a certain data type needs to be changed from the private attribute to the public attribute, or from the public attribute to the private attribute, the data management node modifies the storage attribute in the corresponding mapping relationship and updates the modified mapping relationship to the corresponding smart meter, thereby completing the modification of the storage attribute of the service data of the corresponding data type. Furthermore, in the embodiment of the application, after the storage attribute of the corresponding data type service data is modified, the corresponding data type service data stored in the original node is migrated to the storage node, and the part of service data is migrated according to the updated storage attribute, so that the service data stored in the corresponding storage node meets the real-time data storage requirement.
Furthermore, after the storage attribute of the service data is determined, the service data can be correspondingly stored to the public node or the private node according to the storage attribute of the service data. The public nodes and the private nodes are arranged in a plurality, and the service data are stored in a distributed mode through the public nodes or the private nodes, so that the fault tolerance of service data storage can be improved, the conditions that data are easy to steal and lose due to single node storage are avoided, and the safety of service data storage is guaranteed.
Specifically, the smart meter splits the current service data into a plurality of service data packets, each data packet includes part of service data, and each service data packet further includes mutually redundant part of service data, so as to further improve the fault tolerance of service data storage. It can be understood that, by redundantly backing up part of the service data through each service data packet, even if the service data of one storage node is lost or the storage node is failed, the service data packets of the other storage nodes can be extracted, and the complete service data can be restored through the redundantly backed up service data.
After the intelligent electric meter splits the service data into a plurality of service data packets, each service data packet is further stored to each public node or private node according to the storage attribute of the service data. It should be noted that each service data packet needs to include identification information of the smart meter and timestamp information of the service data. And the subsequent data management node can conveniently inquire and extract the service data according to the corresponding identification information and the timestamp information. And if the storage attribute of the service data is a private attribute, encrypting the service data packet by using the data encryption key, adding the data tag to the service data packet, and storing the service data packet to each private node in a distributed manner. It can be understood that, in order to ensure the security of data storage and extraction and avoid an illegal node from obtaining service data and stealing user privacy information, when the service data packet is stored in each private node, the smart meter encrypts the service data packet by using the encryption key issued in advance in step S110, and adds a data tag issued in advance to the service data packet, so as to facilitate the subsequent data tag comparison and verification to determine whether the identity of the node requesting the service data is legal, thereby improving the security of the data storage and extraction process.
S130, when the data management node extracts the service data, the data management node sends a first data request to each public node, where the first data request includes the identification information and the timestamp information corresponding to the service data, and each public node returns a corresponding service data packet to the data management node in response to the first data request; the data management node sends a second data request to each private node, the second data request comprises the data label, the identification information and the timestamp information corresponding to the service data, each private node responds to the data request to extract the corresponding service data packet, based on the comparison of the data label contained in the service data packet with the data label of the second data request, the identity of the data management node is subjected to common identification verification, whether the identity of the data management node is legal or not is judged, and if the identity of the data management node is judged to be legal, each private node returns the corresponding service data packet to the data management node.
After the storage of the service data is completed, when the data management node needs to extract the corresponding service data, the data management node sends a data request to the corresponding storage node. And the data management node determines the storage attribute of the service data to be requested by inquiring the mapping relation, and further sends a data request to the corresponding public node or private node. Correspondingly, the data request comprises timestamp information of service data to be requested and identification information corresponding to the intelligent electric meter, so that the storage node returns a corresponding service data packet based on the timestamp information and the identification information. And for the data request of the service data stored in the private node, the private node needs to include a corresponding data tag, so that the private node compares the data tag in the data request according to the data tag in the service data packet, and further verifies whether the identity of the data management node is legal or not.
Furthermore, after each public node or each private node receives the data request, a response to the data request is correspondingly performed. And each public node extracts the corresponding service data packet according to the identification information and the timestamp information in the data request and sends the service data packet to the data management node. After each public node receives the data request, because the public node does not set a corresponding authentication means in order to improve the efficiency of data extraction processing, when the public node responds to the data request, the public node directly queries the service data packet stored in the public node according to the timestamp information and the identification information, and returns the service data packet to the data management node.
And for the corresponding private node, in order to guarantee the security of data storage and extraction, the identity of the data management node needs to be verified when the data request is responded. According to the private node, firstly, a service data packet stored inside is inquired according to timestamp information and identification information in the data request, and then the validity of the identity of the data management node is verified according to a data tag of the corresponding service data packet. Specifically, referring to fig. 3, comparing the data tag included in the service data packet with the data tag of the second data request, performing consensus verification on the identity of the data management node, and determining whether the identity of the data management node is legal includes:
s1301, comparing the data labels of the second data request with the data labels by the private nodes according to the data labels, verifying the identity of the data management node according to a comparison result, generating a first identity verification result, summarizing the first identity verification result to a designated consensus node, and selecting the consensus node from the private nodes in advance;
s1302, the consensus node generates a consensus verification result based on each first identity verification result, and determines whether the identity of the data management node is legal based on the consensus verification result.
The embodiment of the application adopts a block chain-based consensus verification mode to carry out identity verification on the data management node. Before the data request is received, the trusted appointed third-party server sends the data labels to the legal data management node and the intelligent electric meter respectively, the intelligent electric meter correspondingly adds the data labels in the service data packets when storing the service data packets to the private node, and the private node compares whether the data labels of the service data packets are consistent with the data labels of the second data request when verifying whether the data management node requesting the service data is legal or not, and if so, the identity of the private node is judged to be legal. Correspondingly, when the data request response of the data management node is carried out, the private node compares the data label of the second data request of the data management node based on the data label of the service data packet. And judging whether the two are consistent according to the comparison result, and outputting a corresponding first identity verification result. Considering that a single private node has network attack and manipulation influences, the embodiment of the present application does not directly use the authentication result of the single private node as the final authentication result. But performs consensus verification based on the first authentication results of the private nodes to determine a final authentication result. The method comprises the steps that a private node is selected from all the private nodes to serve as a consensus node, and the consensus node summarizes first identity verification results of all the private nodes to conduct consensus verification. And the common identification verification adopts a few majority-obeying modes, and if the first identity verification result judges that the identity of the current data management node is legal to exceed 50%, the identity of the data management node is determined to be legal. Otherwise, the current data management node is considered to be illegal, the second data request is ignored, and no data request response is carried out on the second data request. After verifying that the data management node is legal, each private node extracts the corresponding service data packet according to the identification information and the timestamp information in the data request and sends the service data packet to the data management node, so as to complete the response of the data request.
Further, after each public node responds to the data request and returns a corresponding service data packet to the data management node, the data management node analyzes the service data packet, screens out mutually redundant data, and restores the service data; or after each private node returns the corresponding service data packet to the data management node, the data management node decrypts the service data packet by using the reserved data decryption key, screens out mutually redundant data, and restores the service data. It can be understood that, because each service data packet includes mutually redundant partial service data, when the complete service data is restored according to the service data packet, the data management node obtains the complete service data by screening out the redundant partial service data among the service data packets, and performs processing on the related service of the power internet of things based on the service data. However, for the service data packet extracted from the private node, since it is encrypted by using the data encryption key in advance, the data management node needs to decrypt the service data packet by using the reserved data decryption key first, and then restore the service data packet.
