AGNIZE: A NICE Aggregator of Trust
نویسندگان
چکیده
Trust in distributed systems is an inherently difficult problem, as nodes need to decide which other nodes to trust without a central, verifiably trusted authority. This paper evaluates the notion of a distributed sub-network of trust aggregators based on the NICE trust cookie and trust chain system. The aggregators simply keep the trust cookies, which prove delivery of a resource during a transaction. The aggregators can therefore provide an answer about a node’s trustworthiness in O(1) hops. This structure also provides a substrate for a system to track negative trust information as well as to provide global trust values for when direct trust chains do

متن کاملNew Health Technologies: A UK Perspective; Comment on “Providing Value to New Health Technology: The Early Contribution of Entrepreneurs, Investors, and Regulatory Agencies”
New health technologies require development and evaluation ahead of being incorporated into the patient care pathway. In light of the recent publication by Lehoux et al who discuss the role of entrepreneurs, investors and regulators in providing value to new health technologies, we summarise the processes involved in making new health technologies available for use in the United Kingdom.
متن کاملA Novel Charging Plan for PEVs Aggregator Based on Combined Market and Network Driven Approach
With the large-scale production of plug-in electric vehicles (PEVs), a new entity, the PEV fleet aggregator manages charging and discharging processes of the vehicles. The main objective of an individual aggregator in interaction with electricity markets is maximizing its profit. In this paper, the performance of this aggregator in day-ahead and real-time electricity markets, considering (a) cu...
متن کاملRobust Trust Mechanisms for Monitoring Aggregator Nodes in Sensor Networks
Sensor nodes are often deployed in large numbers to monitor extended sensor fields. In such scenarios data aggregation plays a crucial role on summarizing data forwarded to base stations in sensor networks. As sensor networks are commonly deployed in open and unattended areas, they are vulnerable to physical tampering as well as remote attacks. Existing security techniques focus primarily on me...
متن کاملOptimal Decision Making Framework of an Electric Vehicle Aggregator in Future and Pool markets
Electric vehicle (EV) aggregator, as an agent between the electricity market and EV owners, participates in the future and pool market to supply EVs’ requirement. Because of the uncertain nature of pool prices and EVs’ behaviour, this paper proposed a two-stage scenario-based model to obtain optimal decision making of an EV aggregator. To deal with mentioned uncertainties, the aggregator’s risk...
