Radio communication system, shared key management server and terminal
First Claim
1. A radio communication system using a shared key for protecting a security, comprising:
- a first communication network through which data communications are performed;
a second communication network formed independent of the first communication network;
a terminal connecting with the first communication network and the second communication network;
a shared key management server connecting with the first communication network and the second communication network; and
an authentication unit provided to the first communication network;
wherein the shared key management server has a function of generating a shared key by using an issue request of a shared key, output from the terminal through the second communication network, as a trigger, and informing the authentication unit and the terminal through the second communication network of a generated shared key;
the authentication unit has a function of authenticating true/false of the terminal by using an authentication request, output from the terminal based on the shared key, as a trigger, and informing the terminal of an authentication result, and the terminal outputs to the authentication unit the information from the shared key management server as a trigger, and performs data communications through the first communication network based on the shared key by using the authentication result from the authentication unit as a trigger.

Abstract
A shared key management server generates a shared key by using an issue request of a shared key, output from a terminal through a second communication network, as a trigger, and informs an authentication unit and the terminal through a second communication network of the generated shared key. The authentication unit authenticates true/false of the terminal by using an authentication request, output from the terminal based on the shared key, as a trigger, and informs the terminal of the authentication result. The terminal outputs to the authentication unit an authentication request based on the shared key by using the information from the shared key management server as a trigger, and performs data communications based on the shared key through the first communication network by using the authentication result as a trigger.

10. A shared key management server for use in a radio communication system including, a first communication network for data communications performed by a terminal, and a second communication network which is formed independent of the first communication network and is provided for generating a shared key for use in the data communications, the shared key management server comprising:
-
means for receiving an issue request, which receives, from the terminal through the second communication network, an issue request of the shared key for use in the first communication network;
means for generating a shared key, which generates a shared key for the terminal according to the issue request of the shared key from the terminal, the issue request being received at the means for receiving the issue request; and
means for informing a shared key, which informs the terminal and the first communication network of the shared key generated at the means for generating the shared key. - View Dependent Claims (11, 12, 13, 14)

15. A terminal for use in a radio communication system including, a first communication network for data communications performed by the terminal, and a second communication network which is formed independent of the first communication network and is provided for generating a shared key for use in the data communications, the terminal, which connects with the first communication network and the second communication network over a radio channel, comprising:
-
first communication controlling means for controlling radio communications performed through the first communication network;
second communication controlling means for controlling communications performed through the second communication network; and
main controlling means for requesting, via the second communication controlling means, a shared key management server which manages a shared key to issue the shared key, and informs the first communication controlling means of the shared key generated by and input from the server, for use between the first communication controlling means and the first communication network. - View Dependent Claims (16, 17, 18, 19, 20)
