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.

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.

The present invention relates to a method and a system for providing a cloud-based application security service. The system for providing the cloud-based application security service according to the present invention includes: a client device including a compiler, an execution package composition unit, an uploader, and a downloader; and a cloud device including an execution package decomposition unit, a security library providing unit, a security library application unit, and an execution package recomposition unit, thereby, based on a cloud, providing convenience in security application and rapid action against hacker attacks.

Provided is a terminal apparatus with a DRM decoding function and a DRM decoding method in a terminal apparatus. The terminal apparatus with a DRM decoding function comprises a native unit which is provided with a local file memory for storing DRM media content data and an application program for driving a media device player using an operating system; and a DRM decoding unit which reads the DRM media content data from the local file memory using a URL path for web server, when it is required from the application program to reproduce the DRM media content data, and decodes the read DRM media content data, and provides the decoded DRM media content data to the media device player. Therefore, it is possible to reproduce the DRM media content data in the terminal apparatus without the exclusive DRM decoding module.
