A method for identifying signature authentication in a broadcast receiver is dislosed, wherein previous signature authentication identification results for files constituting application programs related to data broadcasting are stored, and when next authentication identification is made for a file, a hashing task for the file is selectively performed based on the previous results. This reduces the number of repeated processes performed for signature authentication, and thus, shortens time required for an application program related to data broadcasting being executed. |
