Sybil-Free Pseudonyms, Privacy and Trust: Identity Management in the Internet of Services
2011 (English)In: Journal of Information Processing, ISSN 1882-6652Article in journal (Refereed) Published
We propose an identity management system that supports role-based pseudonymsthat are bound to a given set of services (service contexts) and supportthe use of reputation systems. Our proposal offers a solution for the problemof providing privacy protection and reputation mechanisms concurrently.The trust information used to evaluate the reputation of users is dynamic andassociated to their pseudonyms. In particular, our solution does not requirethe support or assistance from central authorities during the operation phase.Moreover, the presented scheme provides inherent detection and mitigation ofSybil attacks. Finally, we present an attacker model and evaluate the securityand privacy properties and robustness of our solution.
