A reference model for trust framework based on identity ecosystem

This research work suggests a suitable reference model to develop Trust Frameworks required in Identity Ecosystem proposed by “National Strategy for Trusted Identities in Cyberspace”. Trust Frameworks in Identity ecosystem allows communication with many other frameworks, external users, and departments of private or government organizations. The proper sharing of the digital identity in secure way is the core functionality of this ecosystem. Trust Frameworks need to be governed by policies,rules and regulations from the different views, perspectives and needs to have capacity of being agile, interoperable, flexible and secured. The reference model for Trust Framework must have agile behaviour to adapt the new requirements and changes in models, views, methods, processes and perspectives. Various process models are created to maintain the synchronization between the programs created by different assumptions to build the complex systems. Enterprise architecture frameworks are used to manage these complex systems. Technically, the research compares enterprise architecture frameworks in first phase; secondly, it elaborates the finding with an adaptive system development model. The research classifies enterprise architecture frameworks from different enterprise models/processes, domains, roles, artefacts, tools and perspectives to evaluate their strength in agility, interoperability, flexibility and security layers. The previous works, comparisons from different perspectives are elaborated here as a proof for the need of different a development process like Gill Framework that has adaptability characteristics to build the reference model for Trust Frameworks.
