In this paper, an extended TUX-TMS: A reputation based Trust Management System is presented for enhancing reputation for enabling transaction between unknown users in grid environments. TUX-TMS evaluates trustworthiness and reputation of a domain on the basis of user feedback which is further computed using trust context factor, risk assessment, trust inheritance and trust & reputation decay. TUX-TMS is further extended by including user zones and phylogenetic tree for the users. The parameters are enhanced and redefined to secure transactions and make the information provided more trustworthy. The reputation information is also aggravated hierarchically which enables new entities to inherit domain’s reputation information.
