The trusted sharing system of power grid data is characterized by: include: The sharing classification module is configured to: classify subjects and objects that need to share power grid data; The sharing strategy corresponding module is configured to: match the corresponding sharing strategy to the classified subject and object; The sharing strategies include vertical sharing strategy, hybrid sharing strategy and horizontal sharing strategy; Each sharing strategy first divides the power grid data into features and marks them in sequence, then encrypts the marked features and generates a shared database with the encrypted features; The shared database is shared to the shared body, the shared body decrypts the features, matches the decrypted features and then outputs them; The sharing supplement module is configured to: match the supplement strategy to the data that cannot be shared in the sharing strategy; The horizontal sharing strategy includes: firstly dividing the power grid data into horizontal features, and marking them in sequence, respectively marking them as H1t to Hnt, wherein H1t is the first horizontal feature of the mark, and Hnt is the nth horizontal feature of the mark; Setting first to nth horizontal encryption methods for the first to nth horizontal features respectively, then encrypting the first to nth horizontal features in turn by the first to nth horizontal encryption methods, and generating a horizontal feature sharing database for the encrypted first to nth horizontal features; The subjects and objects that need to share power grid data are classified, including: Setting a shared entity that is the same subject as the power grid and different from the power grid as a horizontal shared entity; A sharing entity that is a subject different from the power grid and has the same object as the power grid is set as a vertical sharing entity; Setting a shared entity that is a subject different from the power grid and an object different from the power grid as a mixed shared entity; The horizontal sharing strategy includes: firstly dividing the power grid data into horizontal features, and marking them in sequence, respectively marking them as H1t to Hnt, wherein H1t is the first horizontal feature of the mark, and Hnt is the nth horizontal feature of the mark; Setting first to nth horizontal encryption methods for the first to nth horizontal features respectively, then encrypting the first to nth horizontal features in turn by the first to nth horizontal encryption methods, and generating a horizontal feature sharing database for the encrypted first to nth horizontal features; The vertical sharing strategy includes: firstly dividing the power grid data into vertical characteristics and marking them in sequence, marking them as Z1t to Zmt, respectively, where Z1t is the first vertical characteristic marked, and Zmt is the mth vertical characteristic marked; Sending a vertical encryption public key to each of the first vertical feature to the mth vertical feature; encrypting each of the first vertical feature to the mth vertical feature using the vertical encryption public key; The hybrid sharing strategy includes: dividing the power grid data and the data of the hybrid sharing body by similarity characteristics, marking the similarity characteristics of the power grid as X1t to Xot in sequence, wherein X1t is the marked first similarity characteristic, and Xot is the marked oth similarity characteristic; A similarity encryption public key is respectively sent to the first similarity feature to the oth similarity feature; and the first similarity feature to the oth similarity feature are respectively encrypted using the similarity encryption public key.

7. A computer device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein: When the processor executes the program, the steps of the method described in any one of claims 1 to 5 are implemented.

8. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the program is executed by a processor, the steps of the method described in any one of claims 1 to 5 are performed.
