A file storage and editing method for random verification and providing a trusted operating environment

Abstract

The invention relates to an information security protecting method, and discloses a file storage and editing method for random check and providing of trusted operating environments. The information security protecting method is implemented by mobile storage equipment, special software and a hardware platform, wherein the interior of the mobile storage equipment is provided with a control chip and a storage; the special software is used for managing the mobile storage equipment; the hardware platform is used for interacting with a user and running the special software; the interior of the storage comprises a trusted operating system area and a storage area, and the storage area is used for storing a target file. The file storage and editing method for random check and providing of the trusted operating environments has the advantages that the stealing of a file in the mobile storage equipment by Trojan viruses under an unknown operating environment is effectively prevented, and the user is allowed to use the designated file under the current environment, meanwhile the stealing of other files under the condition of violating the willingness of the user is avoided, and the user can conveniently use the file; the random check mode is used as the mode authorized by a file system module, and the viruses, such as Trojan, are prevented from controlling the hardware platform to automatically run.

Description

【Technical field】 [0001] The invention relates to a method for protecting information security, in particular to a random check and a file storage and editing method for providing a credible operating environment. 【Background technique】 [0002] Ordinary mobile storage devices, no matter whether they have an encryption function or not, or whether they directly open storage blocks to the computer operating system, or whether manual authorization and confirmation of file access are performed, they all only function as a file carrier. When the file is opened, it always exists in the computer operating system in plain text, and then opened by the corresponding editing software. When the environment where the editing software runs, that is, the operating system and the surrounding software environment itself, there is a risk of confidentiality, it can be said that no matter how to prevent it, it is impossible to guarantee the confidentiality of these files. For example, when ope...
