SuperTrust: a secure and efficient framework for handling trust in super-peer networks

ABSTRACT

In this paper, we describe SuperTrust, a novel and efficient framework designed to handle trust relationships in Super-peer networks. What distinguishes SuperTrust from other works is that trust reports remain encrypted and are never opened during the submission or aggregation processes, thus guaranteeing privacy, anonymity, fairness, persistence and eligibility of transactions.
