Abstract
A secret information storing unit stores a common key which is authenticated between the data storing apparatus and a telecommunications apparatus. A data communication unit receives data from the telecommunications apparatus. The data includes an update of a first data item which is downloaded by the telecommunications apparatus from an information provider via a wireless network and encrypted using the common key. A data storage stores the encrypted update of the first data item received at the data communication unit, and further detaches from the data storing apparatus and independently connects directly to the telecommunications apparatus. The data communication unit sends the encrypted update of the first data item stored in the data storage to the telecommunications apparatus in response to a request from the telecommunications apparatus.
