METHOD FOR PROVIDING SECURITY FOR COMMON INTERMEDIATE LANGUAGE-BASED PROGRAM

摘要

Disclosed is a method for providing security of a program configured by a script language. The present invention provides security for a common intermediate language-based program, which provides security to a user DLL used for a platform supporting an application made of a common intermediate language code and a plug-in made of a native code. The method comprises: a particular function call step of calling a particular function within an application calling a particular module in a secure logic DLL including one or more modules while an application is loaded and executed in a main memory; a DDL request step of making a request for a secure logic DLL to a secure module plug-in for encrypting and storing the secure logic DLL; a DLL generation step of generating a secure logic DLL by decrypting the encrypted DLL in the secure module plug-in; a step of transmitting the secure log DLL to the particular function within the application; and a DLL module call step of calling the particular module included in the secure logic DLL.
