Method for verifying running mapping files

Abstract

The invention provides a method for verifying running mapping files. The method includes the steps that an initial verification value is obtained through calculation according to an algorithm, and then the initial verification value and a first mapping file are merged to form a second mapping file; the second mapping file is loaded through a bootstrap program, the initial verification value is fetched and stored in a nonvolatile memory first, and the first mapping file is run; a verification module is activated through an initialization system and a verification module, and the algorithm is applied through the verification module periodically to work out a verification value of the first mapping file; the verification value of the first mapping file is compared with the initial verification value, verification is to be carried out on the verification value of the first mapping file for the next time if the verification value of the first mapping file is equal to the initial verification value, and a warning is prompted if the verification value of the first mapping file is unequal to the initial verification value. The method aims to verify the running mapping files; when the mapping files in the memory are run, the verification module in the mapping files can verify the mapping files periodically, and the situation that a system runs unstably or collapses and users lose important data due to the fact that the mapping files are tampered or damaged in the running process is prevented.

Description

technical field [0001] The invention relates to a method for verifying an image file of an executable system, especially during the operation of the image file. Background technique [0002] At present, the method for verifying the image file of the executable system mainly encrypts the image file itself that is not running, so as to prevent the image file from being tampered with during storage or transmission. However, there is no relevant technical method for verifying the image file in the running process. [0003] The patent document published on October 15, 2008 with the announcement number CN101288083 and titled "Program Executable Image Encryption" discloses a method for encrypting non-running image files. By using the commands in the source file, the executable The sections of the image are marked to be encrypted, and the executable image is compiled to produce an object file, a linker is used to join one or more of the executable images to produce a final executab...

[0005] The existing verification method can only encrypt and protect the image during the storage or transmission of the image file, but after the image file is tampered with or destroyed after running, the user cannot know that when the image file is severely damaged, it may Can cause system paralysis and user loss of important data
