Distributed Ledger Technologies (DLTs), like Blockchain, are characterized by features such
as transparency, traceability, and security by design. These features make the adoption of …

For wireless sensor networks (WSNs), many factors, such as mutual interference of wireless
links, battlefield applications and nodes exposed to the environment without good physical …

Trust and reputation management over distributed systems has been proposed in the last
few years as a novel and accurate way of dealing with some security deficiencies which are …

Most attempts at analysing secure information flow in programs are based on domain-
specific logics. Though computationally feasible, these approaches suffer from the need for …

Trust networks among users of a recommender system (RS) prove beneficial to the quality
and amount of the recommendations. Since trust is often a gradual phenomenon, fuzzy …

Abstract Wireless Sensor Networks (WSNs) are becoming more and more spread and both
industry and academia are focusing their research efforts in order to improve their …

Recommendation technologies and trust metrics constitute the two pillars of trust-enhanced
recommender systems. We discuss and illustrate the basic trust concepts such as trust and …

Different trust and/or reputation models have arisen in the last few years. All of them have
certain key processes in common such as scoring, ranking, rewarding, punishing or …

Trust and distrust are two increasingly important metrics in social networks, reflecting users'
attitudes and relationships towards each other. In this paper, we study the indirect derivation …

Trust and reputation models research and development for distributed systems such as P2P
networks, wireless sensor networks (WSNs) or multi-agent systems has arisen and taken …
