The researches on ITS are actively carried aiming to improve safely, amenity, and efficient transportation. However the researches on ITS systems including the security are few. So we proposed the secure gateway which is constructed the secure channel and makes service continue for DSRC(Dedicated Short Range Communications) network or wireless network. In this paper, we develop and evaluate this secure gateway under DSRC network and report these results. Moreover, the application domain of our proposal is discussed.
