    摘要: Disclosed is a broadcasting signal receiving apparatus for controlling use of a broadcasting program using a signature in program information and a method thereof. The broadcasting signal receiving apparatus includes a communicating unit for receiving a broadcasting signal, an extracting unit for extracting a broadcasting program and program information from the received broadcasting signal, and a determining unit configured to generate a temporal signature for confirmation (confirmation signature) which determines whether the program information is changed or not from the original program information and determine validity of the program information by comparing a signature included in the extracted program information with the confirmation signature.
