Embodiment 1

[0087] Please refer to figure 1 , which is a flowchart of a method for securely storing data provided in Embodiment 1 of the present application, the method includes:

[0088] S101: The first trusted execution environment authenticates the first application program successfully, receives the storage instruction of the first application program for the first data, and parses the storage instruction, and the storage instruction is based on the second trusted execution environment. The first data is written; wherein, the first trusted execution environment is the underlying operating environment of the first operating system, and the first application is an upper-layer application of the first operating system;

[0089] S102: The second trusted execution environment successfully authenticates the first trusted execution environment, and receives the storage instruction; the second trusted execution environment is the second operating system;

[0090] S103: In response to the sto...

Embodiment 2

[0129] Based on the same inventive concept as in Embodiment 1 of this application, Embodiment 2 of this application provides an electronic device, please refer to Figure 6 ,include:

[0130] housing 10;

[0131] The memory 20 is arranged in the casing 10, wherein the memory includes a first storage device and a second storage device, and the first storage device is used for storing the first system file corresponding to the first operating system and the first system file corresponding to the first operating system. an application program file corresponding to the application program, the second storage device is used to store a second system file corresponding to the second operating system;

[0132] a processor 30, arranged in the housing 10, configured to receive a storage instruction of the first application program for the first data when the first trusted execution environment successfully authenticates the first application program, and parse the storage instruction, ...

Abstract

The invention discloses a method for secure storage of data and electronic equipment. The method comprises steps as follows: a first credible execution environment authenticates a first application successfully, receives a storage instruction of the first application for first data and analyzes the storage instruction, and the storage instruction represents to perform write operation on the first data on the basis of a second credible execution environment; the second credible execution environment authenticates the first credible execution environment successfully and receives the storage instruction; the second credible execution environment is a second operation system; the second credible execution environment responds to the storage instruction and writes the first data in a storage device corresponding to the second credible execution environment in a preset encryption mode, and the first data written in the storage device in the preset encryption mode are invisible to an upper-layer application of a first operation system.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for safely storing data and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic technology has also developed rapidly. Many electronic devices, such as tablet computers, smart phones, etc., have become the necessities of people's daily life. In order to meet user requirements, electronic devices can generally be used to run various operating systems or application programs, which brings great flexibility to the electronic devices. [0003] In the prior art, since the electronic equipment can support the operation of various application programs, the careless operation of the user will also cause malicious processes such as various Trojan horses and viruses to enter the electronic equipment. For example, when the user clicks on a virus-carrying website, the virus will parasitize in the operating sy...
