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.

In a method for verifying the integrity of first to Nth binaries (N is a natural number greater than or equal to 2), the method may comprise: loading the first to Nth binaries into a main memory in order to execute the binaries; verifying a self hash to verify, by the Kth binary (K=1, . . . , N&#x2212;1) which has been loaded into the main memory, the integrity thereof by using a hash; and verifying a link hash by setting any one of the first to Kth binaries as a verification binary and setting a (K+1)th binary to be loaded into the main memory as a binary to be verified so that the verification binary verifies the integrity of the binary to be verified by using a hash.

Method of verifying integrity of program using hash

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.
