Abstract

Embodiments of the present invention provide a data security processing method and apparatus. The method includes the steps of acquiring a to-be-encrypted data block, wherein the to-be-encrypted data block includes N pieces of to-be-encrypted data, each piece of to-be-encrypted data is corresponding to a unique index identifier, and N is an integer greater than or equal to 1; encrypting the N pieces of to-be-encrypted data sequentially, acquiring N pieces of encrypted data, and recording a storage position of the N pieces of encrypted data; and generating index data according to the storage position of the N pieces of encrypted data and the index identifiers, wherein the index data includes a mapping relationship between the storage position of the N pieces of encrypted data and the N index identifiers. Through adoption of the data security processing method and apparatus provided by the embodiments of the present invention, data storage security is improved, and data read efficiency is improved.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data security processing method and device. Background technique [0002] With the rapid development of the information society, more and more fields need to analyze and process various data to guide the production or business process. In order to prevent competitors from knowing the relevant data, many data storage processes need to be encrypted. For example: Quota list database data. Quota refers to the quantitative standard of manpower, material resources, financial resources and time consumed in the production of qualified unit products under certain technical and organizational conditions. The data in the quota inventory database includes a large amount of data content. In order to ensure that the data will not be arbitrarily obtained without authorization, the data storage process needs to be encrypted. [0003] In the prior art, a commonly used data encryption method is t...
