[0042] FIG. 4 is a diagram showing an example of a system configuration according to the first embodiment of the present invention. The system shown in Figure 4 includes: a client 1 such as a PC (personal computer), a cellular phone or a PDA (personal digital assistant) used by a user receiving a service; a plurality of service servers 2 providing a service; a user authentication device 3 for authenticating a ticket; and a user management database 4 for managing user information. This user authentication device 3 includes: a user authentication control unit 31, which is used to perform the main part of generating and decoding the authentication ticket process; a ticket pool (user information temporary storage unit) 32, which is used for limited Save user information within a time limit; and an expiration time monitoring unit 33, configured to monitor the expiration time of an entry in the ticket pool 32 and delete the entry accordingly.

[0058] Fig. 11 is a diagram showing a processing flow from a service request to a service start according to the second embodiment. In this second embodiment, it is stipulated that the expiration time of the user information stored in the ticket pool is updated.

[0059] In the first embodiment, user information in the ticket pool 32 is discarded after a certain period of time has elapsed regardless of whether decoding requests are continuously issued as part of a series of operations. Thereafter, user information is acquired from the user management database 4 in response to the decoding request. This may establish a situation where decoded information does not match between the first half of the decoding process and the second half of the decoding process. When multiple services make multiple decoding requests in succession, these services often constitute interrelated applications. In this case, therefore, it is preferable to obtain the same information as a decoding resu...

[0066] FIG. 13 is a diagram showing the structure of a ticket pool according to a third embodiment of the present invention. In the third embodiment, it is stipulated that the upper limit of the extended expiration time can be set.

[0067] In the second embodiment, the user information in the ticket pool 32 is not discarded if decoding requests are continuously issued at short intervals, as in the case of decoding request congestion. In this case, there will be no situation where user information is acquired from the user management database 4 . That is, the intended purpose of a stand-alone ticket, namely to return user information that was present at the time the request was decoded, is completely defeated. Therefore, in the third embodiment, user information stored in the ticket pool 32 is managed in conjunction with an extension upper limit in addition to the expiration time.

[0068] In FIG. 13 , the ticket pool 32 includes a key 32a for storing individual tickets, an ...

Abstract

An authentication ticket processing apparatus includes a temporary data storage unit configured to keep user information upon receiving the user information from a user management database for managing user information, the temporary data storage unit allowing access thereto to be performed at higher speed than access to the user management database. The authentication ticket processing apparatus is configured such that, when there is a need to acquire user information in response to a decoding request from a server, a check is made whether user information corresponding to the decoding request is present in the temporary data storage unit, and the corresponding user information is acquired from the temporary data storage unit if the corresponding user information is present in the temporary data storage unit.

Description

technical field [0001] The invention relates to an authentication ticket processing device capable of accelerating the acquisition of user information. Background technique [0002] For servers on the network, authentication tickets can be used to provide fast and secure services. [0003] According to different purposes, authentication tickets have different specifications. One of these specifications concerns an authentication ticket called a "self-contained ticket" that returns user information when decoded. [0004] FIG. 1 is a diagram showing the flow from an authentication request to obtaining an authentication ticket in the prior art. Before receiving a service from the service server 2, the client 1 issues an authentication request to a user authentication device (UAUD: User Authentication via User Directory) 3 (step S1). The user authentication device 3 checks user information using the user management database 4 (step S2). Once confirmed, the user authenticatio...
