CRC METHOD AND SERVER FOR VERIFICATION DETECTION OF MEMORY PROTECTING FILE USING CRC ALGORISM

摘要

The present invention relates to a method and a server for detecting a forgery and falsification of a memory protection file using a CRC algorithm for performing file forgery detection using a CRC algorithm for a file to which a memory protection function is applied, A method for detecting forgery / falsification of a memory protection file using the CRC includes: extracting data whose memory address is not changed after memory-loading the memory protection file; Generating and storing a plurality of file signatures by classifying the extracted data by function, generating CRC values for each function, and mapping memory addresses; Providing the memory protection file to the client terminal; Receiving randomly selected one of a plurality of file signatures, notifying the client terminal of a memory address included in the randomly selected file signature, and receiving a CRC value for data stored in the notified memory address from the client terminal; And checking whether the memory protection file is forged or falsified by comparing and analyzing the feedback CRC value and the CRC value included in the randomly selected file signature.
