Accounting management method for grid computing system

摘要

An accounting management method in grid computing which ensures security and validity and reduces manager burdens is disclosed. An accounting certificate for a server in which a tariff for computing resources available on the server is stated and attached with the digital signature of a certificate authority (CA) of accounting is prepared. An accounting certificate for resources user (ACRU) in which a credit authorized for the user to be spent to utilize resources is stated and attached with the digital signature of the CA of accounting is prepared. When initiating a session in which the client submits a request for service processing to a server and obtains a response, the client sends the server the ACRU and a proxy including a credit amount allocated for service usage in the session as a part of the authorized credit and attached with the client's digital signature. The server authenticates the signatures on the ACRU and proxy in a concatenate way by using a public key of the CA of accounting and accepts the request for service processing. If the server calls on a subordinate server to execute a part of the processing, the server creates a second proxy including a credit amount allocated for sub-processing as a part of the credit stated in the foregoing proxy and passes the second proxy to the subordinate server.
