An efficient approach based on trust and reputation for secured selection of grid resources

Abstract

Grid computing refers to the harnessing of computer systems by newlinecollaboratively solve a problem requiring a large number of Central newlineProcessing Unit CPU or data storage and processing which is far more than newlineone system to handle Though used primarily in technical and scientific newlineprojects grid computing is gaining popularity in the corporate world because newlineof its costsaving potential Security is a principal concern in offering an infrastructure for the formation of general purpose computational grids A number of grid newlineimplementations have been devised to deal with the security concerns by newlineauthenticating the users hosts and their interactions in an appropriate fashion newlineResource management systems that are sophisticated and secured are newlineinevitable for the efficient and beneficial deployments of grid computing newlineservices The chief factor that could be problematic in the secured selection newlineof grid resources are the wide range of selection and the high degree of newlinestrangeness Moreover the lack of a higher degree of confidence relationship newlineis likely to prevent the efficient resource allocation and utilization newline newline
