Authentication Information Alignment for Cross-Domain Federations

Abstract

With the rapid deployment of distributed systems and the Internet, federation activities such as online collaboration and information sharing become pervasive. Trust is a big issue in these federation activities. To manage trust in federation activities, authentication information needs flexible manipulation to accommodate technical and managerial requirements. To achieve identity federation across domains, authentication information must sometimes be adjusted, transformed, augmented, or substituted during the authorization and verification operations. In this paper, we propose a plug-in style alignment using a wavelet transformation to manipulate authentication information for verification and authentication. We incorporate BioAPI in our implementation to extend the capability of our system to adapt to different authentication models and technologies. Experimental results show that the overhead of this plug-in alignment is negligible.
