A trust infrastructure for Grid security module

During the procedure of resource discovery in Grid, a requester (consumer) may be offered several resources (providers) which identities have been verified to submit his task. How to make decision on selecting providers to complete his job reliably is an emergency. Establishing trust system is an alternative to respond the challenge. For the sake of future works in computational Grid are to refine the existing models, to define and to develop additional components, so define the trust model infrastructure for grid security module is necessity. This paper analyzes the fundamental trust requirements, proposes a trust signaling prototype and developments of our simulating trust mould which with we proposed computational model and signaling model for Grid security module is discussed at the end.
