A new class of Virtual Private Networks (VPN), which supports both security and mobility, has recently emerged. Called mobile VPN, these systems provide not only secure tunnels but also session continuity mechanisms despite location change or connection disruptions. These mechanisms enable secure sessions to survive in dynamic/mobile environments without requiring a renegotiation of security keys during the session resumption phase. In this paper, we compare four open-source mobile VPNs in terms of functionality and performance.
