20130182844TERMINAL APPARATUSES AND BASE STATION APPARATUS FOR TRANSMITTING OR RECEIVING A SIGNAL CONTAINING PREDETERMINED INFORMATION - When a first symmetric key table is received, a storage unit stores the received first symmetric key table that indicates a plurality of kinds of symmetric keys. The storage unit also stores beforehand a second symmetric key table in an area larger than an area where the first symmetric key table is usable. A determining unit determines whether or not a terminal apparatus is present within the area where the first symmetric key table is usable. When the terminal apparatus is determined to be present within the area, a verification unit generates a digital signature with a symmetric key contained in the first symmetric key table. When, on the other hand, the terminal apparatus is determined to be present outside the area, the verification unit generates the digital signature with a symmetric key contained in the second symmetric key table.07-18-2013
