Abstract

The invention provides a data encryption method and device. The method comprises the steps of obtaining to-be-transmitted data; determining the data level of the to-be-transmitted data according to the data type, the data format or the interactive interface of the to-be-transmitted data, wherein the data level comprises advanced data and general data; when it is determined that the data level of the to-be-transmitted data is advanced data, encrypting the to-be-transmitted data by using a pre-generated public and private key pair, and sending the encrypted to-be-transmitted data to a client, wherein the public and private key pair comprises a public key and a private key; and carrying out double encryption processing on the private key, and sending the private key subjected to double encryption processing to a super SIM card set by the client. According to the data encryption method provided by the scheme, the data to be transmitted is subjected to data level division, whether encryption is carried out or not is determined according to the data level corresponding to the current data to be transmitted, and the private key is subjected to double encryption processing, so that the data security is improved.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a data encryption method and device. Background technique [0002] With the rapid development of the digital economy era, data security protection technology has become the focus of research. [0003] In the prior art, usually during the transmission of these data, the data is encrypted through an encryption method selected by the user, so as to ensure the security of the transmitted data. [0004] However, complex encryption methods will lead to slow data analysis and transmission speed, while simple encryption methods cannot guarantee the security of data transmission. Both encryption methods have certain limitations. Therefore, there is an urgent need for a method that can overcome the above limitations A permanent data encryption method is of great significance to improving the security and efficiency of data transmission.
