Embodiment Construction

[0039] In the following description, for illustrative purposes, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is obvious that these embodiments can also be implemented without these specific details. In other examples, for the convenience of describing one or more embodiments, well-known structures and devices are shown in the form of block diagrams.

[0040] In order to solve the above problems, the present invention uses three encryption methods to encrypt data. When a user uploads data, first, use a reversible algorithm to encrypt the data uploaded by the user, and then use an irreversible algorithm for the user’s login password to generate an asymmetric algorithm. Public key, use the public key of an asymmetric encryption algorithm to encrypt the secret key of the decrypted data to form a ciphertext; when the user downloads data, use the private key of the asymmetric encryption algorithm to decry...

Abstract

The invention provides a method and a device for ciphering and deciphering data in a management system. The method includes the steps: generating a public key and a private key of an RSA algorithm according to login passwords of a user when the user login management system uploads data; ciphering a secret key randomly generated by the management system by the RSA algorithm according to the public key to generate a secret key ciphertext, ciphering the data uploaded by the user according to the secret key ciphertext by a reversible algorithm and storing the ciphered data when the user login management system uploads the data, and deciphering the secret key ciphertext according to the private key by the RSA algorithm to obtain the secret key when the user login management system downloads the ciphered data; deciphering the ciphered data according to the deciphered secret key by the reversible algorithm; downloading the data after obtaining the deciphered data. By the method and the device, data ciphering security can be improved, support of a client is not needed in the data ciphering process, and the user can cipher and decipher the data without redundant operations.

Description

Technical field [0001] The present invention relates to the field of data encryption technology, and more specifically, to a method and device for encrypting and decrypting data in a management system. Background technique [0002] With the development of computer network technology and the popularization of Internet technology, Web management system structure has been widely used, especially in some enterprise information management and government administration management systems, it has become the main management method; part of the information data in the Web management system It is absolutely confidential. It is related to the development and survival of the enterprise. Once these confidential data are stolen or maliciously tampered with, this will inevitably bring huge economic losses to the enterprise. Therefore, the data encryption of the Web management system is to protect data security. Important means. [0003] The data encryption in the Web management system has the fo...
