1. a kind of execute homomorphic cryptography to generate the computer implemented method of summation, which comprisesAt server,The server generates multiple encrypted payloads, and the encrypted payloads all have multiple data values,The data value of each of the encrypted payloads is positioned in the encrypted payloads by the serverThe lower half of each,The upper half of each of the encrypted payloads is remained sky, and offer and the first kind by the serverIt is worth each of associated multiple first keys and the encrypted payloads with the multiple data value, describedA corresponding data value for data value in each of each of one key and described encrypted payloads is associated,And the multiple first key is configured as matching with the first kind offset, the first kind offset and and Second Type valueAssociated multiple second keys are associated, to define intersection, andBased on request, the server decryption is related to the intersection between the multiple first key and the multiple second keyConnection blinds product, and the product that blinds includes:

  • that an encryption in included encrypted payloads in the intersection effectively carriesOne or more data values of lotus and one in other one or more encrypted payloads included in the intersectionOr the product that other multiple data values are multiplied.
