Fig. 1 is a schematic flowchart of a method for processing electric energy metering data according to an embodiment of the present invention.

As shown in FIG. 1 , the method for processing electric energy metering data includes an uploading and processing method 100 for electric energy metering data and a receiving and processing method 200 for electric energy metering data used in conjunction with the uploading and processing method 100 for electric energy metering data. The execution subject of the method 100 for uploading and processing electric energy metering data may be a data concentrator. The data concentrator is used for summarizing the electric energy metering data of a corresponding corresponding number of electric power users. The execution subject of the electric energy metering data receiving and processing method 200 may be a power system server of a power company.

Referring to FIG. 1 , the method 100 for uploading and processing electric energy metering data includes the following steps 110 - 170 .

Step 110, regularly divide the electric energy metering data to be processed into two groups according to users, and obtain the first group of electric energy metering data and the second group of electric energy metering data.

In this embodiment, at intervals of one month, for example, on the first day of the current month, the electric energy metering data to be processed can be divided into two groups according to users 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 is the electric energy metering data of the power user in the previous month.

Each power user corresponds to a set of electric energy metering data. Taking the example of 100 sets of electric energy metering data to be processed in this embodiment, the 100 sets of electric energy metering data correspond to 100 electric power users. The users are randomly divided into two groups. For example, any 50 users can be divided into the first group. The electric energy metering data of the 50 users constitute the first group of electric energy metering data, and the electric energy metering data of the remaining 50 users are automatically The second group of electric energy metering data is formed.

Step 120, using the encryption module of the preset symmetric encryption algorithm, using the preset first encryption key to encrypt the first group of electric energy metering data to obtain the first ciphertext data, and using the preset second encryption key to encrypt The second ciphertext data is obtained from the second group of electric energy metering data.

In this embodiment, the symmetric encryption algorithm uses the AES encryption algorithm, the first encryption key is K1, and the second encryption key is K2. When in use, the encryption module using the symmetric encryption algorithm uses the first encryption key as K1 to encrypt the first group of electric energy metering data obtained in step 110 to obtain the first ciphertext data. Correspondingly, the encryption module adopting the symmetric encryption algorithm uses the second encryption key to encrypt the second group of electric energy metering data obtained in step 110 to obtain the second ciphertext data.

Step 130, using a preset asymmetric encryption algorithm, using a preset public key, encrypting the first encryption key to obtain the first encryption key ciphertext, encrypting the second encryption key to obtain the second encryption key ciphertext .

Step 170, upload the second mixed data F2 to the power system server after receiving the electric energy metering data summary instruction from the power system server.

After receiving the electricity metering data aggregation instruction sent by the power system server, the second mixed data F2 stored locally in step 160 is directly uploaded to the power system server. It can be seen that the present invention does not need to collect the electric energy metering data corresponding to the summarized electric power users after receiving the electric energy metering data summary instruction sent by the power system server, which improves the efficiency of the electric power system server for collecting electric energy metering data to a certain extent.

Referring to FIG. 1 , the method 200 for receiving and processing electric energy metering data includes the following steps 210 - 280 .

Step 210, acquire the second mixed data F2 transmitted in the method 100 for uploading and processing electric energy metering data.

Step 220, splitting the second mixed data F2 to obtain the first mixed data F1 and digital digest M.

Step 230, using the MD5 algorithm to calculate the digital digest of the first mixed data F1 obtained from the splitting, to obtain the digital digest M'.

Step 240, verify whether the calculated digital digest M' is the same as 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, then the first mixed data F1 split in step 220 has data integrity.

Step 250, when it is verified that the calculated digital digest M' is the same as the digital digest M obtained by splitting, split the first mixed data F1 to obtain the first ciphertext data, the second ciphertext data, and the first ciphertext data. An encryption key ciphertext and a second encryption key ciphertext.

Specifically, the first ciphertext data, the second ciphertext data, the first An encryption key ciphertext and a second encryption key ciphertext.

Step 260, based on a preset asymmetric encryption algorithm, using a preset key corresponding to the public key, decrypt the ciphertext of the first encryption key to obtain the first encryption key, decrypt the The second encryption key ciphertext obtains the second encryption key.

Corresponding to the asymmetric encryption algorithm in the method 100 for uploading and processing electric energy metering data, the RSA encryption algorithm that is exactly the same as the asymmetric encryption algorithm in step 130 is used in step 260 .

Step 270, based on the decryption module of the preset symmetric encryption algorithm, use the decrypted first encryption key to decrypt the first ciphertext data to obtain the first set of electric energy metering data, and use the decrypted second encryption key to decrypt the second The ciphertext data obtains the second set of electric energy metering data.

Corresponding to the symmetric encryption algorithm in the method 100 for uploading and processing electric energy metering data, the AES encryption algorithm that is exactly the same as the symmetric encryption algorithm in step 120 is adopted in step 270 .

Step 280, storing the decrypted first set of electric energy metering data and the second set of electric energy metering data.

The first set of electric energy metering data and the second set of electric energy metering data obtained by decrypting in step 270 are stored.
