TUX-TMS: Thapar University Extensible-Trust Management System

In a Grid Computing scenario, where the market players are dynamic; traditional assumptions for establishing and evaluating trust, do not hold good anymore. There are two different methods for handling access controls to the resources either by using policy based approach where logical rules and verifiable properties are encoded in signed credentials or using reputation based approach where trust values are collected, aggregated and evaluated to disseminate reputation among the market players. There is need for a dynamic and flexible general-purpose trust management system. In this paper TUX-TMS: an extensible reputation based Trust Management System is presented for establishing and evaluating trust in grid systems. TUX is an efficient Reputation based trust management system for establishing secure Grids.
