Securing Route Optimisation in NEMO

The Network Mobility (NEMO) Basic Support protocol enables mobile networks to change their point of attachment to the Internet, while preserving established sessions of the nodes within the mobile network. When only a nonnested mobile network is considered, the so-called triangle routing is the main problem that should be faced. In Mobile IPv6, the Route Optimisation mechanism solves this problem, and the Return Routability mechanism aims to limit the security concerns originated because of the Route Optimisation. Nowadays Return Routability is considered a weak solution (i.e., based on strong assumptions). In this article we explore different approaches to Route Optimisation in NEMO and we devise how to adapt some of the Terminal Mobility solutions to a NEMO environment, where, as we will propose, a delegation of signalling rights from the Mobile Network Node to the Mobile Router is necessary.
