Towards a Trust Management Enabled Identity Metasystem

Abstract

Existing identity metasystems provide enabling tools to manage, select, and control of digital identities but they have not provided the support of trust management that should cover how trust requirements associated with digital identities are modeled, how runtime conditions for trust are evaluated, and how the results of trust evaluation are consumed by systems/applications. In this paper, the authors propose an approach toward a trust management enabled identity metasystem that covers the analysis of trust requirements and the development of trust management system in a consistent manner. The proposed trust management architecture extends the existing identity metasystems by introducing computing components for carrying out typical trust management tasks associated with digital identities. The computing components in proposed architecture provide intelligent services for these tasks. The proposed high level architecture targets the automation of the development of the trust management layer for digital identities.
