The recent supply of smartphone and the late change in the internet environment had lead users to demand safe services. Especially, the VPN technology is being researched as a key technology for providing safe services within the cloud environment or the data-center environment. However, the openness of IP is a critical threat to the VPN technology, which provides service via sharing IP address of its gateway. The exposed IP address is venerable to many kinds of attacks, and thus VPN gateway and its service are also venerable to these threats. This paper proposes a VHSP mechanism, which prevents exposure of IP address by assigning temporal IP address for the VPN gateway and its services. VHSP assign temporal IP address per-user bases. Moreover, this paper had verified performance of VHSP and original VPN in various conditions.
