Storing apparatus and telecommunications apparatus
First Claim
1. A data storing apparatus connectable to a telecommunication apparatus for supplying direct current power to the telecommunication apparatus, comprising:
- a power source unit that converts an alternating current into a direct current;
a powering unit configured to supply the direct current power to the telecommunications apparatus connected to the data storing apparatus;
a secret information storing unit configured to store a common key used for authenticating data communicating between the data storing apparatus and the telecommunications apparatus via a data communication unit of the data storing apparatus;
the said data communication unit configured to receive the data from the telecommunications apparatus, which receives the data from an information provider via a wireless network in response to a request from the telecommunications apparatus;
wherein the data including an update of a first data item which is downloaded and encrypted using the common key by the telecommunications apparatus;
wherein the download starts only when an authentication by valid pair sharing of the common key becomes successful; and
a data storage configured to store the encrypted update of the first data item received at the data storing apparatus, the data storage further configured to detach from the data storing apparatus and independently connect directly to the telecommunications apparatus, whereinthe data storing apparatus 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.

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.
