APPLICATION CODE CONCEALMENT APPARATUS USING DUMMY CODE, AND APPLICATION CODE CONCEALMENT METHOD USING SAME

摘要

An application code concealment apparatus comprises: a critical code separator for separating application codes into critical codes and general codes other than the critical codes; a critical code caller generating unit for generating a critical code caller for calling the critical codes; a code analyzing unit for analyzing the critical codes; a dummy code generating unit for generating dummy codes corresponding to the critical codes; a code encrypting unit for encrypting the critical codes; a code arranging unit for arranging the dummy codes and the encrypted critical codes, and generating location information of the dummy codes and the encrypted critical codes; a code decoder generating unit for generating a code decoder for decoding the encrypted critical codes; a loader generating unit for generating a loader for loading the decoded critical codes and the dummy codes into a memory; a decoded code caller generating unit for generating a decoded code caller for calling the decoded critical codes loaded in the memory; and an unloader generating unit for generating an unloader for unloading, in a process of executing the decoded critical codes, the dummy codes and the executed critical codes from the memory.
