Network mobility route optimization with certificate-based authentication

The International Civil Aviation Organization has adopted IPv6 as the network protocol for the future Aeronautical Telecommunications Network, with Mobile IPv6 (MIPv6) as the baseline protocol to provide IP mobility. For aircraft, the Network Mobility (NEMO) extension to MIPv6 has to be considered, but this protocol does not yet provide any Route Optimization procedure, although many proposals do exist. We present a new mechanism that complements an existing Route Optimization proposal for NEMO, thus making it feasible for the aeronautical environment. This approach is based on certificates that should allow reducing signalling overhead and handover delay while providing a higher level of security.
