Abstract

The invention discloses a label function processing method and device, and relates to the technical field of computer security. The problem that in the prior art, label functions are deleted not thoroughly is solved. The method comprises the steps of obtaining label function information in an import table, wherein the label function information includes a label function name and an address of a label function in a memory; creating a relocation function block according to the label function information; when a program executes the label function, relocating the label function to the relocation function block. The method and device are mainly used for label function processing.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a label function processing method and device. Background technique [0002] In software security protection, software developers usually define a unified label for functions that need to be protected during the software development process, and add the label to the functions that need to be protected. Software developers find the tags in the program by importing the dynamic library, and then protect the tagged functions, and need to delete the tagged functions after completion. [0003] However, in the prior art, when deleting the label function, if the deletion is not complete, when the program runs to the position corresponding to the label function, the program will crash; in addition, if only the label function is simply set to the nop instruction, it will It leaves traces for software crackers to find key codes, so the security of the software cannot be guaranteed.
