A Bilinear Pairing Based Key Management Security Scheme to NEMO in Heterogeneous Networks

Network Mobility (NEMO) is invented for providing internet to group of nodes (smart phones, ipad and laptop).It is inherited from Mobile IPv6. There are security threats inside the NEMO during handoff while exchanging Binding Updates (BU) between the Mobile Network Node (MNN), Correspondent Node (CN) and Home Agent (HA). It may prone to several malicious attacks also during the network address exchange between nodes inside the NEMO. A proper end-to-end security mechanism is required to protect the Binding Update and Binding Acknowledgement. We have proposed a security architecture to provide authentication and confidentiality at each and every level of communication (MNN ↔ HA, MR ↔ HA, MNN ↔ CN)using a 3-Party Key Exchange called (3-PKE-NEMO) with the help of Bilinear Pairing Theorem. This architecture also provides security to Route Optimization (RO). We have minimized handoff delay and shown results using the NS2 simulator without compromising the security. Our security architecture is found to be more efficient when compared with related existing solutions.
