Integrating Certificate Services with Grid Widgets for a Computational Grid Platform

Abstract

Large-scale parallel computing is increasingly relying on multi-clusters and Grids, and user authorization on computing nodes is an important issue. To contribute the issue, the certificate authority (CA) public key infrastructure (PKI) service has been integrated with Grid Widgets by the Distributed Computing Team in National Center for High-performance Computing (NCHC). NCHC CA PKI service has been operating since 2008, which provides supports for certificate services integrated with Grid Widgets. At a beginning Grid session, a Grid proxy credential should be created to delegate a user identity for Grid interactions. Moreover, the excellent way leads the convenient management of the credential lifetime on the computational Grid platform.
