Embodiment Construction

[0039] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

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

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 technical field of data encryption, 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, the structure of Web management system has been widely used, especially in some enterprise information management and government affairs management systems, it has become the main management method; part of the information data in the Web management system It is absolutely confidential, and it is related to the development and survival of the enterprise. Once these confidential data are stolen or maliciously tampered with, it 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] However, the data encryption in the Web management ...
