<p><P>PROBLEM TO BE SOLVED: To make it unnecessary for a user to input any password in using a resource without damaging safety when the user preliminarily reserves the resource on a distributed computing system. <P>SOLUTION: A job scheduler 200 transmits a resource reservation request to a resource proxy 300, and the resource proxy 300 generates a pair of a reservation process certificate issue request including a reservation target resource, a period and a public key and a secret key corresponding to the public key, and transfers the reservation process certificate issue request through the job scheduler 200 to a host computer 100. The host computer 100 prepares an electronically signatured reservation process certificate by using a user proxy credential or a user credential, transfers it as a reservation decision request through the job scheduler 200 to the resource proxy 300, and performs user authentication by using a pair of the reservation process certificate stored on the resource proxy 300 and the secret key when the resource is used. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
