The novel idea suggests that any NHI VPN site can only establish tunnels by a secure mechanism, which requires a NHI Healthcare IC card state machine to certificate. A tunnel was then built, which dynamically filters packet headers according to the IC Card operating states in association with filter statements. Currently there are no related researches similar to our approach, as we know in the literature. An emulated prototype was constructed. The overhead in performance degradation is negligible. The efficient and secure tunnel would support more potential NHI added-value applications.en-US資訊處國際醫學資訊研討會論文集conference
