Title:
APPLICATION CODE HIDING DEVICE THROUGH CODE MODIFICATION IN MAIN MEMORY UNIT AND APPLICATION CODE HIDING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/012693
Kind Code:
A1
Abstract:
An application code hiding device comprises: a critical code separation unit for separating application codes into critical codes and general codes other than the critical codes; a critical code caller generation unit for generating a critical code caller for calling the critical codes; a code analysis unit for analyzing the critical codes; a dummy code generation unit for generating dummy codes corresponding to the critical codes; a code encryption unit for encrypting the critical codes; a code arrangement 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 generation unit for generating a code decoder for decoding the encrypted critical codes; an arranged code importer generation unit for generating an arranged code importer for transferring the dummy codes and the encrypted critical codes using the location information of the dummy codes and the encrypted critical codes; a code loader generation unit for generating a code loader for loading the dummy codes into a memory; an in-memory code modifier generation unit for generating an in-memory code modifier for replacing the dummy codes loaded in the memory by the decoded critical codes; and a decoded code caller generation unit for generating a decoded code caller for calling the replaced decoded critical codes into the memory.
