Data processing method, device and electronic equipment

Abstract

The embodiment of the invention provides a data processing method, a device and electronic equipment. The method comprises the steps: obtaining a to-be-sorted array A, and enabling the to-be-sorted array A to comprise N elements with ciphertext values; carrying out n1 rounds of sorting on the to-be-sorted array A, wherein the following steps are executed in each round of sorting: to-be-sorted elements in the to-be-sorted array A in the current round are determined, and the to-be-sorted elements in the current round are elements except for one element with the determined position in the elements after the last round of sorting; sequentially performing ciphertext comparison on two adjacent elements A [i] and A [i + 1] in the to-be-sorted elements to obtain a corresponding ciphertext comparison result H; exchanging the positions of the two adjacent elements A [i] and A [i + 1] according to the ciphertext comparison result H so as to determine the position of one element in the elements tobe sorted in the current round of sorting; wherein the ciphertext comparison result H is a ciphertext of 0 or 1; and thus, the sorting of the ciphertext array is realized.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing method, device and electronic equipment. Background technique [0002] With the continuous development of computers, communication technologies, and Internet technologies, most users will use electronic devices to transmit and store information, such as uploading files to cloud storage, sending files to other users, and so on. Among them, in order to ensure the security of information, the data is usually encrypted. For example, in the process of data storage, the data will be encrypted on the corresponding storage electronic device, such as data encryption on the server and terminal; The data is encrypted during the process, such as the data is encrypted during the transmission of the data between the terminal and the server. [0003] When an electronic device needs to use these data, it is necessary to decrypt the data first, obtain the plaintext of the informa...

Problems solved by technology

[0004] Usually, in some scenarios based on ciphertext calculation, it is necessary to sort a set of data, but since these data are all ciphertext, it is impossible to judge which data is large and which data is small, resulting in the inability to sort the ciphertext data
