Embodiment Construction

[0054] In order to facilitate understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will be described below first.

[0055]When the front-end and the back-end exchange information, in order to ensure the security of the information, the packets are usually encrypted. However, in some scenarios, limited by the development framework of the front-end system, it is impossible to encrypt the message as a whole, and a field-by-field encryption method is required. However, the fields of packets carrying different information are different, and the method of encrypting each field requires a lot of time and has poor flexibility, so it is impossible to perform differential processing for fields with different security requirements.

[0056] Based on this, the embodiments of the present application provide a message encryption method, message decryption method, device and syste...

Abstract

The invention discloses a message encryption method, device and system, and a message decryption method, device and system.The method comprises the steps that during encryption, a to-be-processed form is obtained, when it is determined that the to-be-processed form needs to be encrypted based on encryption configuration parameters, a to-be-encrypted field in the to-be-processed form is determined through the encryption configuration parameters, the to-be-encrypted field is encrypted, and an encrypted field is obtained; and finally, generating an encrypted message based on the field in the to-be-processed form. The to-be-processed form needing to be encrypted and the specific to-be-encrypted field needing to be encrypted in the to-be-processed form can be determined through the encryption configuration parameters. The field needing to be encrypted and decrypted can be determined by using the encryption configuration parameter and the decryption configuration parameter, and the message to be processed does not need to be decrypted integrally, so that the decryption cost can be reduced.

Description

technical field [0001] The present application relates to the technical field of data security, and in particular, to a message encryption method, a message decryption method, an apparatus and a system. Background technique [0002] During the process of accessing the web page, the user may enter some information. After acquiring the information input by the user, the front end of the web page will generate a message based on the acquired information, and send the message to the server. After obtaining the packet, the server processes the information carried in the packet. [0003] The information entered by the user may include information with a higher security level. In order to avoid the risk of information leakage and tampering in the process of processing and transmitting information, the packets transmitted between the front end of the web page and the server are encrypted. However, the current encryption method is cumbersome and difficult to meet the needs of mess...
