A Survey on Secure and Resilient Session Schemes: Technical Comparison and Assessment

Cyber threats become more and more pervasive on the Internet and on distributed/decentralized systems. In order to secure communication over these infrastructures and respond to mobility constraint, a new class of Virtual Private Networks (VPN), which support both security and mobility, has emerged in the course of last years. Mobile Virtual Private Networks, called mobile VPN, provide not only secure tunnels but also session continuity mechanism despite location change or connection disruptions. This mechanism enables secure sessions to survive in dynamic/mobile environments without requiring a renegotiation of security keys during the session resumption phase. In this paper, on the one hand, we survey the recent literature on the mobile VPN systems followed by a detailed analysis and a technical comparison in tabulated form of existing technologies. On the other hand, we carry out experiments on open source mobile VPN infrastructures. We subsequently outline and discuss major features and performances of various assessed mobile VPN infrastructures.
