Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Example 1:
fig. 1 is a schematic flow chart of a method of processing electric energy metering data according to an embodiment of the present invention.
As shown in fig. 1, the processing method of the electric energy metering data includes an electric energy metering data uploading processing method 100 and an electric energy metering data receiving processing method 200 used together with the electric energy metering data uploading processing method 100. The subject of the power metering data upload processing method 100 may be a data concentrator. The data concentrator is used for summarizing the electric energy metering data of the corresponding number of electric power users. The execution subject of the electric energy metering data receiving processing method 200 may be a power system server of an electric power company.
Referring to fig. 1, the method 100 for uploading the electric energy metering data includes the following steps 110-170.
And step 110, dividing the electric energy metering data to be processed into two groups according to users at regular intervals to obtain a first group of electric energy metering data and a second group of electric energy metering data.
In this embodiment, for example, on the first day of the month, the electric energy metering data to be processed may be divided into two groups according to the user to obtain the first group of electric energy metering data and the second group of electric energy metering data. The electric energy metering data to be processed are the electric energy metering data of the last month of the electric power user.
Each power consumer corresponds to a group of electric energy metering data, taking 100 groups of electric energy metering data to be processed in this embodiment as an example, the 100 groups of electric energy metering data correspond to 100 power consumers, the electric energy metering data to be processed can be divided into two groups according to the users at regular intervals, for example, 50 arbitrary users can be divided into a first group, the electric energy metering data of the 50 users form the first group of electric energy metering data, and the electric energy metering data of the remaining 50 users automatically form the second group of electric energy metering data.
Step 120, an encryption module of a preset symmetric encryption algorithm is adopted, a preset first encryption key is used for encrypting the first group of electric energy metering data to obtain first ciphertext data, and a preset second encryption key is used for encrypting the second group of electric energy metering data to obtain second ciphertext data.
In this embodiment, the symmetric encryption algorithm adopts an AES encryption algorithm, where the first encryption key is K1, and the second encryption key is K2. When the encryption module adopting the symmetric encryption algorithm is used, the first encryption key is used as K1, and the first group of electric energy metering data obtained in the encryption step 110 is used to obtain first ciphertext data. Correspondingly, the encryption module adopting the symmetric encryption algorithm encrypts the second set of electric energy metering data obtained in the step 110 by using the second encryption key to obtain second ciphertext data.
And 130, encrypting the first encryption key by adopting a preset asymmetric encryption algorithm and using a preset public key to obtain a first encryption key ciphertext, and encrypting the second encryption key to obtain a second encryption key ciphertext.
In this embodiment, the asymmetric encryption algorithm adopts an RSA encryption algorithm, and a public key is preset to be K3. When the encryption method is used, the public key is used, the first encryption key and the second encryption key are encrypted respectively through the asymmetric encryption algorithm, and a first encryption key ciphertext and a second encryption key ciphertext are correspondingly obtained.
And 140, splicing the first ciphertext data, the second ciphertext data, the first encryption key ciphertext and the second encryption key ciphertext into first mixed data F1 according to a preset sequence.
The predetermined order may be any order of the first ciphertext data, the second ciphertext data, the first encryption key ciphertext, and the second encryption key ciphertext, for example, the first ciphertext data, the second ciphertext data, the first encryption key ciphertext, and the second encryption key ciphertext may be sequentially arranged, or the first encryption key ciphertext, the second ciphertext data, the first ciphertext data, and the second encryption key ciphertext may be sequentially arranged, which may be predetermined by a person skilled in the art according to actual situations.
Step 150, calculating the digital digest of the first mixed data F1 by using the MD5 algorithm to obtain a digital digest M.
The digital digest M is used to verify the integrity of the first hybrid data F1.
In step 160, the first mixed data F1 and the digital digest M are spelled into second mixed data F2 and stored locally.
The second mixed data F2 comprises the first mixed data F1 and the digital abstract M, the first mixed data F1 is formed by splicing the first ciphertext data, the second ciphertext data, the first encryption key ciphertext and the second encryption key ciphertext, and therefore the complexity of data uploaded to the power system server is increased to a certain extent, and further the safety and the integrity of electric energy metering data uploaded to the power system server are improved.
Step 170, after receiving the electric energy metering data summarizing instruction sent by the electric power system server, uploading the second mixed data F2 to the electric power system server.
After receiving the electric energy metering data summarizing instruction sent by the electric power system server, the second mixed data F2 stored locally in step 160 is directly uploaded to the electric power system server. Therefore, the invention does not need to collect the electric energy metering data corresponding to the summarized power users after receiving the electric energy metering data summarizing instruction sent by the power system server, and improves the efficiency of the power system server for summarizing the electric energy metering data to a certain extent.
Referring to fig. 1, the method 200 for processing the electric energy metering data includes the following steps 210-280.
Step 210, obtain the second mixed data F2 transmitted in the electric energy metering data uploading processing method 100.
Step 220, splitting the second mixed data F2 to obtain the first mixed data F1 and the digital digest M.
In step 230, the MD5 algorithm is adopted to calculate the digital digest of the split first mixed data F1, so as to obtain a digital digest M'.
Step 240, verifying whether the calculated digital digest M' is identical to the split digital digest M.
If the calculated digital digest M' is the same as the digital digest M obtained by splitting in step 220, the first mixed data F1 obtained by splitting in step 220 has data integrity.
Step 250, when the digital digest M' obtained by the verification and calculation is the same as the digital digest M obtained by the splitting, splitting the first mixed data F1 to obtain the first ciphertext data, the second ciphertext data, the first encryption key ciphertext and the second encryption key ciphertext.
Specifically, the first ciphertext data, the second ciphertext data, the first encryption key ciphertext, and the second encryption key ciphertext for stitching the first hybrid data F1 may be reversely split according to a predetermined order for stitching the first hybrid data F1.
Step 260, based on a preset asymmetric encryption algorithm, adopting a preset key corresponding to the public key to decrypt the first encryption key ciphertext to obtain a first encryption key, and decrypting the second encryption key ciphertext to obtain a second encryption key.
In step 260, the RSA encryption algorithm identical to the asymmetric encryption algorithm in step 130 is used, corresponding to the asymmetric encryption algorithm in the power metering data uploading processing method 100.
Step 270, based on the decryption module of the preset symmetric encryption algorithm, decrypts the first ciphertext data using the decrypted first encryption key to obtain a first set of electric energy metering data, and decrypts the second ciphertext data using the decrypted second encryption key to obtain a second set of electric energy metering data.
Corresponding to the symmetric encryption algorithm in the power metering data upload processing method 100, the AES encryption algorithm identical to the symmetric encryption algorithm in step 120 is adopted in step 270.
Step 280 stores the decrypted first and second sets of electrical energy metering data.
The first and second sets of electrical energy metering data decrypted in step 270 are stored.
Example 2:
embodiment 2 is different from embodiment 1 in that the processing method of electric energy metering data in this embodiment further includes: in step 160, the second mixed data F2 is stored locally, which specifically includes: determining whether the second mixed data F2 satisfies a preset data dividing condition:
if yes, dividing the second mixed data F2 into corresponding data blocks meeting the preset size according to preset dividing rules, and storing the data blocks to the local;
if not, directly storing the second mixed data F2 to the local;
in step 170, after receiving the electric energy metering data summarizing instruction sent by the electric power system server, uploading the second mixed data F2 to the electric power system server, which specifically includes: after receiving an electric energy metering data summarizing instruction sent by a power system server, judging whether the locally stored data blocks are segmented:
if yes, uploading all the divided data blocks to a power system server in parallel;
if not, the second mixed data F2 stored locally is directly uploaded to the power system server.
Correspondingly, in step 210, the second hybrid data F2 transmitted from the electric energy metering data uploading processing method is obtained, including:
receiving the uploaded data and judging whether the received data is a segmented data block or not:
if yes, merging the received data blocks to obtain the second mixed data F2;
