An Iterative Algorithm for Trust and Reputation Management

" An Iterative Algorithm for Trust and Reputation Management" Erman Ayday, Hanseung Lee, Faramarz Fekri Abstract: Trust and reputation play critical roles in most en­ vironments wherein entities participate in various transactions and protocols among each other. The recipient of the service has no choice but to rely on the reputation of the service provider based on the latter's prior performance. This paper introduces an iterative method for trust and reputation management referred as ITRM. The proposed algorithm can be applied to centralized schemes, in which a central authority collects the reports and forms the reputations of the service providers as well as report/rating trustworthiness of the (service) consumers. The proposed iterative algorithm is inspired by the iterative decoding of low-density
