Abstract

A communication apparatus comprises a storage unit for storing a first network list indicating plural networks; a receiving unit for receiving a second network list indicating plural networks from an outside by using a first authentication protocol; an operation unit for executing an AND operation by using the first network list and the second network list to create a transmission-use network list; and transmission unit for transmitting the transmission-use network list to the outside.

Claims

1. A communication apparatus, comprising:

a storage unit for storing a first network list indicating plural networks;

a receiving unit for receiving a second network list indicating plural networks from an outside by using a first authentication protocol;

an operation unit for executing an AND operation by using the first network list and the second network list to create a transmission-use network list; and

a transmission unit for transmitting the transmission-use network list to the outside.

2. The communication apparatus according to claim 1, wherein the transmission unit transmits the transmission-use network list by using a second authentication protocol different from the first authentication protocol.

3. The communication apparatus according to claim 1, wherein the operation unit creates the transmission-use network list only including a network matching between the first network list and the second network list.

4. The communication apparatus according to claim 1, wherein the first authentication protocol is a RADIUS protocol.

5. The communication apparatus according to claim 2, wherein the second authentication protocol is an EAP (Extensible Authentication Protocol.

6. The communication apparatus according to claim 1, further comprising a transmission request unit for requesting transmission of the second network list.

7. The communication apparatus according to claim 1, wherein the communication apparatus is an authentication switch or an authentication server.

8. The communication apparatus according to claim 7, wherein the first network list is network identification information for identifying a network usable by the authentication switch, and the second network list is network identification information for identifying a network usable by a user registered in the authentication server.

9. The communication apparatus according to claim 7, wherein the first network list is network identification information for identifying a network usable by a user registered in the authentication server, and the second network list is network identification information for identifying a network usable by the authentication switch.

10. A communication program for causing a computer to execute, comprising:

a storage step of storing a first network list indicating plural networks;

a receiving step of receiving a second network list indicating plural networks from an outside by using a first authentication protocol;

an operation step of executing an AND operation by using the first network list and the second network list to create a transmission-use network list; and

a transmission step of transmitting the transmission-use network list to the outside.

11. The communication program according to claim 10, wherein the transmission step includes transmitting the transmission-use network list by using a second authentication protocol different from the first authentication protocol.

12. The communication program according to claim 10, wherein the operation step includes creating the transmission-use network list only including networks matching between the first network list and the second network list.

13. The communication program according to claim 10, wherein the first authentication protocol is a RADIUS protocol.

14. The communication program according to claim 11, wherein the second authentication protocol is an EAP (Extensible Authentication Protocol.

15. The communication program according to claim 10, further comprising a transmission request step of requesting transmission of the second network list.

16. A communication method, comprising:

a storage step of storing a first network list indicating plural networks;

a receiving step of receiving a second network list indicating plural networks from an outside by a using first authentication protocol;

an operation step of executing an AND operation by using the first network list and the second network list to create a transmission-use network list; and

a transmission step of transmitting the transmission-use network list to the outside.

17. The communication method according to claim 16, wherein the transmission step includes transmitting the transmission-use network list by using a second authentication protocol different from the first authentication protocol.

18. The communication method according to claim 16, wherein the operation step includes creating the transmission-use network list only including networks matching between the first network list and the second network list.

19. The communication method according to claim 16, wherein the first authentication protocol is a RADIUS protocol.

20. The communication method according to claim 17, wherein the second authentication protocol is an EAP (Extensible Authentication Protocol.

21. The communication method according to claim 16, further comprising a transmission request step of requesting transmission of the second network list.
