Secure Connection Re-establishment for Session-Based IP Mobility

Abstract

The Session-based IP Mobility Support [1] is a general purpose socket-based API designed to create mobility-aware applications that do not break with transmission disruptions or delays. In this paper, we present and discuss the security support provided in order to deal with threats in the phases of closed session opening and suspended session reopening. The performance of these phases were assessed through experiments in a real wireless network and compared with handshake approaches of the most common upper layer protocols, such as TCP, SSL, and SSH. The operation latency results show a good cost-effectiveness of the secure session support, which is an important requirement for handling IP mobility in Vehicular Communication Networks (VCN). Using the developed protocol, the detection of link disruption and the trusted re-establishment of an ongoing connection can be achieved with little overhead.
