Extending existing campus trust relationships to the Grid through the integration of Pubcookie and MyProxy

Abstract

In many ways, the ultimate success of the Grid will be highly dependent on the support for and integration with existing legacy infrastructure such as authentication infrastructure. This paper describes the design and implementation of the integration of Pubcookie, a popular Web-based authentication infrastructure used on campuses, and MyProxy, the on-line credential repository for the Grid. Specifically, we enable a valid Pubcookie credential to be dynamically exchanged for a Grid credential, without requiring the user to reauthenticate. Through this integration, this project makes an important contribution to an overall goal of single sign-on and more specifically the ability to "authenticate locally and act globally". © Springer-Verlag Berlin Heidelberg 2005.
