Abstract: | To improve trustworthiness in grid authentication, a novel trust enhanced grid authentication mechanism (TEGAM) is proposed
in this paper where trust is divided into trust on grid entity (GE) and trust on third party (TP). In order to obtain precise
trust evaluation on GE’s behaviors, trust on GE is further subdivided into trust as service consumer and trust as service
provider. Details for the structure of TEGAM and related TEGAM-based authentication process are also given. Simulation results
and property analysis show that, compared with current trust-based grid authentication techniques, TEGAM can not only help
establish explicit and dynamic trust relationships among grid entities but also will significantly increase the efficacy of
grid authentication.
