Disclosed are an apparatus and a method for providing security and an apparatus and a method for executing security to protect a code of a shared object. An apparatus for providing security includes: an object file extraction unit configured to extract a shared object file from an execution package; an object management unit configured to store separately a value of at least one tag of an initialization-function-related section of the shared object file and provide a security shared object file generated by populating with 0 the value of the at least one tag of the shared object file; a security module generation unit configured to generate a security module file including the value of the at least one tag separately stored by the object management unit; and a packet assembly unit configured to generate a security execution package including an execution engine library, a security shared object file provided by the object management unit, and a security module file provided by the security module generation unit, thereby completely protecting the important execution code of the shared object file from a static analysis attack.

Apparatus and method for providing security and apparatus and method for executing security to protect code of shared object

Disclosed are an apparatus and a method for providing security and an apparatus and a method for executing security to protect a common intermediate language. An apparatus for providing security storing an execution package generated by assembling an execution engine library and an intermediate language library generated by compiling a plurality of files includes: an intermediate language extraction unit configured to extract the intermediate language library from the execution package; and an encryption unit configured to provide a secure intermediate language library by encrypting the intermediate language library extracted from the intermediate language extraction unit through a first encryption algorithm and encrypting the encrypted intermediate language library through a second encryption algorithm, thereby protecting the common intermediate language from hacking.
