MUSeS: Mobile User Secured Session

Mobility and security are very important services for both current and future network infrastructures. However, the integration of mobility in traditional virtual private networks is difficult due to the costs of reestablishing broken secure tunnels and restarting broken application connections. In order to address this issue, we propose a new communication system called Mobile User Secured Session. Based upon a peer-to-peer overlay network, it provides security services to the application layer connections of mobile users. The secure and resilient sessions allow user connections to survive network failures as opposed to regular transport layer secured connections. We have implemented a prototype and have assessed its proper functioning by running experimentations upon a simple virtual dynamic network.
