First Claim
Patent Images
1. A method of communication of a client with a first server, the method comprising:
- transmitting a static identifier and a first dynamic identifier to a second server;
receiving from the second server a second dynamic identifier created by the second server by updating the first dynamic identifier; and
accessing the first server based on the second dynamic identifier,wherein the first dynamic identifier is a dynamic identifier previously received from the second server in a previous process to communicate with the first server.

5. A method of communication of a first server with a client, the method comprising:
-
receiving from a second server a static identifier and a second dynamic identifier created by updating a first dynamic identifier, of the client; and allowing an access of the client based on the second dynamic identifier, wherein the second server receives from the client the static identifier and the first dynamic identifier, determines whether a previous dynamic identifier corresponding to the static identifier is identical to the first dynamic identifier in a determination, updates the first dynamic identifier based on a result of the determination to create a second dynamic identifier, and transmits the second dynamic identifier to the client. - View Dependent Claims (6, 7, 8, 18)

9. A client apparatus communicating with a first server comprising:
-
a certification interface which transmits a static identifier and a first dynamic identifier to a second server, and receives from the second server a second dynamic identifier created by the second server by updating the first dynamic identifier; and a communication interface which accesses the first server based on the second dynamic identifier, wherein the first dynamic identifier is a dynamic identifier previously received from the second server in a previous process to communicate with the first server. - View Dependent Claims (10, 11, 12)

13. A first server apparatus communicating with a client comprising:
-
a certification interface which receives from a second server a static identifier and a second dynamic identifier created by the second server by updating a first dynamic identifier; and a communication interface which allows an access of the client based on the second dynamic identifier, wherein the second server receives from the client the static identifier and the first dynamic identifier, determines whether a previous dynamic identifier corresponding to the static identifier is identical to the first dynamic identifier in a determination, updates the first dynamic identifier based on a result of the determination to create a second dynamic identifier, and transmits the second dynamic identifier to the client. - View Dependent Claims (14, 15, 16)
