Cloud data encryption method

Abstract

The invention provides a cloud data encryption method, comprising the following steps: S101, generating a primary key by adopting a random number; and S201, according to the primary key, generating asecondary key, and carrying out encryption / decryption processing on a database by utilizing the secondary key, wherein the secondary key comprises a plurality of bits of record name fields which are required to be checked and stored in a database table and a plurality of bits of column information fields temporarily produced in the database table, and adding the column information behind each record name once the record name is added in the database. The cloud data encryption method provided by the invention can greatly increase large integer factorization difficulty, and security of public key cryptography is guaranteed to the utmost extent, so that data security is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cloud data security management, and in particular relates to a cloud data encryption method. Background technique [0002] At present, with the rapid development of computer and electronic communication technology, including the Internet, the pace of financial electronicization has been greatly accelerated. This electronic and digital trend has affected almost all aspects of social life. Many communication activities between people, including commercial trade, financial affairs and other economic activities, have already flowed on the Internet in the form of digital information. The research, implementation and standardization of e-commerce, e-banking and e-money are ongoing. In full swing. Many important documents that are traditionally based on paper and often require signature and seal, such as deposit certificates, checks, stocks, official letters, contracts, leases, wills, ballots, legal documents, ...

AI Technical Summary

Problems solved by technology

Compared with conventional technologies, cloud technology truly achieves the integration and utilization of resources, and has higher convenience and flexibility, but the security issues caused by resource sharing cannot be ignored. With the development of computer technology at any time, traditional The encryption method ignores various attacks due to the loopholes in the details, resulting in the public key password being cracked and resulting in data leakage
