Apparatus and method of providing security and apparatus and method of executing security for common intermediate language

A method of providing security, the method comprising:

• storing an execution package generated by assembling a shared object file and an execution engine library;
• extracting the shared object file from the execution package;
• storing separately a value of at least one tag of an initialization-function-related section of the shared object file, populating with 0 the value of the at least one tag of the shared object file, and providing a security shared object file;
• generating and providing a security module file including the value of the at least one tag separately stored in the providing of the security shared object file;
• and
• generating a security execution package including the execution engine library, the security shared object file provided in the providing of the security shared object file, and the security module file provided in the generating of the security module file.

A method of executing security, the method comprising:

• calling a dynamic loader for a shared object file through an operating system;
• loading the shared object file into a memory by an operation of the dynamic loader and receiving a base address of the loaded shared object file;
• reading a value of at least one tag in an initialization-function-related section of the separately stored shared object file and adding the value to the base address;
• and
• fetching an initialization function address stored in an address generated by adding the value of the tag to the base address and calling a corresponding initialization function.
