In this embodiment, when the tax administration platform encrypts the intermediate result, a preferred implementation manner is that the intermediate result is encrypted based on a public key included in the key pair.
In practical application, a tax party (a tax management platform) and an electric power party (an electric power management platform) are data interaction participants, and before the tax and electric power indexes are calculated, a preferable implementation mode is that a data sandbox (a mature data sandbox product is applied here, and data ownership and data use right are separated to ensure that the data circulation process is safe and controllable) is deployed.

The tax information system comprises information of data of a tax party and a third party, wherein the data of the tax party comprises basic collection and management data, value-added tax invoice data, enterprise data and tax payment data of enterprises. The data of the third party comprises electric power data, industry standard data, enterprise pollution data and the like.

and the decryption unit is used for receiving the encrypted target tax-electricity index sent by the power management platform and decrypting the encrypted target tax-electricity index to obtain the target tax-electricity index.
7. The apparatus of claim 6, wherein the apparatus further comprises:
the generating unit is used for generating a key pair based on a preset rule, sending a public key included in the key pair to the power management platform, and maintaining a private key included in the key pair locally.
8. The apparatus according to claim 7, wherein, when performing encryption processing on the intermediate result, the encryption unit is specifically configured to:
and encrypting the intermediate result based on the public key included in the key pair.
9. The apparatus of claim 7 or 8, wherein the power management platform encrypts the target tax indicia based on a public key included in the key pair;
and when the encrypted target tax index is decrypted to obtain the target tax index, the decryption unit is specifically configured to:
and decrypting the encrypted target tax-electricity index based on the private key included in the private key pair to obtain the target tax-electricity index.
10. A tax-power-indicating computing device for use in a power management platform, the device comprising:
the receiving unit is used for receiving a tax-electric-label calculation formula sent by the tax management platform, an encrypted intermediate result and a power-side data directory required by calculation of a target tax-electric label, wherein the tax management platform calculates the intermediate result required by calculation of the target tax-electric label based on the target tax-side data after determining the target tax-side data required by calculation of the target tax-electric label based on the tax-electric-label calculation formula;
the encryption unit is used for calculating the target tax-electricity index according to the encrypted intermediate result and the target electric power side data based on the tax-electricity index calculation formula and encrypting the target tax-electricity index;
and the sending unit is used for sending the encrypted target tax-related indicia to the tax management platform, so that the tax management platform decrypts the encrypted target tax-related indicia after receiving the encrypted target tax-related indicia, and obtains the target tax-related indicia.
