Data aggregation method using addition postposition item and multiplication postposition item

Abstract

The invention discloses a data aggregation method using an addition postposition item and a multiplication postposition item, which comprises a data sender, a data calculator and a data receiver, andcomprises the following steps: the data sender blinds data; the data calculator performs addition and multiplication calculation on the data blinded by the data sender; after receiving the calculationresult of the data calculator, the data receiver removes blind data in the result to obtain a final plaintext calculation result; the obtained plaintext calculation result is verified; because the addition postposition item and the multiplication postposition item added each time have randomness, even if the blinded plaintext information is the same, the blinded ciphertext does not expose any information of the plaintext, and the received data can be correctly used only by knowing the related information related to the blinded data, so that even if the blinded ciphertext is intercepted by anenemy, the enemy cannot correctly use the intercepted ciphertext, and cannot obtain plaintext related information.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data aggregation method using post-terms of addition and post-multiplication. Background technique [0002] Encryption of plaintext data is a common data processing technique. Most of the existing plaintext encryption is processed and encrypted on the existing plaintext, and the secret of the activity often contains the information recorded in the original plaintext data, so that it cannot be decrypted without decryption. Technical means may also obtain the information recorded in the original plaintext data, and then lead to the leakage of plaintext data information. For this reason, we propose a data aggregation method using additive postterms and multiplicative postterms. Contents of the invention [0003] The purpose of the present invention is to provide a data aggregation method using additive postterms and multiplicative postterms to solve the problems raised i...
