Efficient NEMO security management via CAP-KI

Network Mobility (NEMO) has gained much momentum ever since being introduced. The concept of NEMO, is actually building on top of the MIPv6 and using MIPv6 as its backbone. The differences are much align at the capability of the Router being able to roam freely, hence the term Mobile Router (MR). Whereas in the MIPv6 world, there is only fix Access Router (AR). Since the NEMO is directly associated with MIPv6 as the backbones building blocks, the NEMO concepts has also inherits the security management systems of which MIPv6 is adapting. As the matter of fact, the NEMO concept has exposed greater security risks with the use of IPSec as the security design. Coupled with nested looping concept and capability that NEMO offered, the use of IPSec as the security design will no longer be sufficient from the efficiency point of view. In this paper, we will illustrate the use of IPSec on NEMO, and zooming into the instances whereby nested looping comes into picture and how security system will be at risk and finally proposing a new security design system to counter the inefficiencies.
