Embodiment Construction

[0057] The technical solution of the present invention will be described in detail below in combination with specific embodiments and accompanying drawings, so as to make it more clear.

[0058] Such as figure 1 Shown is an application environment diagram of the terminal data encryption method of an embodiment, which includes the current terminal and its internal structure. The terminal data encryption method can be applied to the current terminal, and the terminal includes a processor connected through a system bus, a non-volatile A volatile storage medium, a network interface, an internal memory, and an input device, wherein the non-volatile storage medium of the terminal stores an operating system. The processor is used to provide computing and control capabilities, which may include the ability to implement data encryption to support the operation of the entire terminal. The internal memory in the terminal provides an environment for the operation of the operating system ...

Abstract

The invention relates to a terminal data encryption method and system and a terminal data decryption method and system and relates to the technical field of data encryption. The terminal data encryption method includes: acquiring to-be-encrypted original text and the configuration information of a current terminal, determining a target data encryption type associated with the configuration information of the current terminal according to the preset association relationship of the configuration information and the data encryption type, determining a secrete key and an encryption algorithm according to the target data encryption type, and encrypting the to-be-encrypted original text according to the secrete key and the encryption algorithm. The terminal data encryption method has the advantages that the data encryption type is determined according to the acquired configuration information of the current terminal, the secret key and the encryption algorithm are determined according to thedata encryption type, the to-be-encrypted original text is encrypted by using the secrete key and the encryption algorithm, the cracking difficulty of the secret key and the encryption algorithm is increased, large-scale exposure of the secret key is prevented, terminal encryption compatibility is increased, and terminal data encryption safety is increased.

Description

technical field [0001] The present invention relates to the technical field of data encryption, in particular to a terminal data encryption method and system, and a terminal data decryption method and system. Background technique [0002] The application data of the terminal is generally stored in the public file storage, so whether it is a system loophole or a file management system without permission control, it may bring greater risks to the application data. Therefore, through data encryption, the terminal's Application data protection is essential. [0003] The traditional terminal data encryption method is to obtain key information according to the data to be encrypted, and then encrypt the data according to the key information and a public encryption algorithm. Among them, the key information is stored in the local storage or in the application code. [0004] However, the key information in the traditional terminal data encryption method is easy to be reversely deci...
