Example Embodiment

[0065] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0066] In the process of encrypting data, the present invention generates a string of random numbers for each original text to be encrypted, then generates a primary key based on the password and the random number, and extracts part of the data from the primary key as the encryption key , And then use the encryption key to encrypt the original text to obtain the primary ciphertext, and finally perform data fusion on the primary ciphertext and the random number to obtain the final ciphertext. In the process of decrypting data, first decompose the final ciphertext according to the password provid...

Abstract

The invention relates to the field of information security and provides a method, system and device for data encryption and decryption. The data encryption method includes the following steps: A. obtaining an original text to be encrypted and receiving passwords input by users; B. generating random numbers according to the original text, and generating primary keys on the basis of the passwords and random numbers and extracting encrypted keys from the primary keys; C. encrypting the original text with the encrypted keys to obtain a primary cipher-text; D. making data integration of the primary cipher-text and random numbers to obtain a final cipher-text. In addition, a data encryption and decryption system, a data encryption and decryption device and a data decryption method are also provided, which then improves the security of data storage.

Description

technical field [0001] The present invention relates to the field of information security, and more specifically, to a data encryption and decryption method, system and equipment. Background technique [0002] At present, a large number of service providers, such as software-as-a-service (SaaS) providers, usually provide financial, customer relationship management, supply chain management and other software to customers. When a customer uses the services provided by these software, the customer's data needs to be stored in the service provider's public database. If the data is not encrypted, some sensitive data may be leaked. To avoid this from happening, it is necessary to encrypt the data. [0003] There are many existing data encryption methods, including symmetric encryption algorithm, asymmetric encryption algorithm, irreversible encryption algorithm and so on. in: [0004] The symmetric encryption algorithm is an earlier encryption algorithm with mature technology. ...
