Embodiment Construction

[0053]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] Such as figure 1 As shown, in an embodiment, an application environment diagram of an information encryption method is provided, and the application environment diagram includes a mobile terminal 110 and a server 120 . The mobile terminal 110 can communicate with the server 120 through a network. The mobile terminal 110 may be at least one of a smart phone, a tablet computer, a notebook computer, a POS machine, and a vehicle-mounted computer, but is not limited thereto. The server 120 may be an independent physical server, or a server cluster composed of multiple physical servers. The mobi...

Abstract

The invention relates to a method for encrypting information. The method comprises the following steps that: when an application program in a mobile terminal is monitored to be switched in an on state, a secret key character string is generated randomly and the generated secret key character string is stored; when the application program sends a communication request to a server for the first time, the generated secret key character string is encrypted asymmetrically by using a server public key published by the server in advance and the encrypted secret key character string is sent to the server; a document uploading request triggered by a user in the application program interface is obtained; a document carried by the document uploading request is analyzed, a privacy field in the document is localized, and the privacy filed is encrypted symmetrically by using a secret key character string generated randomly to generate a document ciphertext; and the generated document ciphertext is uploaded to the server, so that the server decrypts the uploaded document ciphertext based on the received encrypted secret key character string and a server private key. With the method provided by the invention, the information decryption and encryption processing efficiency is increased and the safety is enhanced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an information encryption and decryption method, device, computer equipment and storage medium. Background technique [0002] With the development of the Internet and the application of cloud computing, more and more tasks tend to store data in the cloud. However, these data often contain some sensitive information. In order to protect the privacy of the data, it is necessary to encrypt the sensitive private information. [0003] Traditional data encryption methods include symmetric encryption and asymmetric encryption. Asymmetric encryption is more secure, but when a large amount of private information is involved in the transmitted document, the encryption and decryption time takes a long time and the speed is slow. Therefore, asymmetric encryption is only suitable for encrypting a small amount of data, while symmetric encryption needs to fix the secret key locally ...
