Trust management for grid Environment

Abstract

Trust management is an important issue in grid computing where newlinethe consumers and Resource Providers RP are distributed geographically newlineacross autonomous domains This research addresses the establishment of newlinetrustworthiness of the entities and proposes trust management architectures newlineIn single broker architecture one broker is associated with each of newlinethe administrative domain In such a centralized architecture with all the newlinerequests and feedback being collated and processed by a single broker there newlineis a possibility of heavy traffic at the broker s site and the broker is heavily newlineloaded This architecture also may lead to a single point failure newlineThe proposed multi broker trust management framework insists on newlinemultiple brokers in each domain The entities consumers and RPs are newlinedistributed across these brokers with each of these being associated with newlinemore than one broker This improves redundancy of information maintained at newlinethe broker s site thereby improving the reliability This also eases the network newlinetraffic at the broker site while handling consumer requests and feedback due newlineto the distribution of requests and feedback across multiple brokers in each newlinedomain compared to the single broker architecture newline newline
