Mobile IPv6 (mipv6) is an internet protocol that allows mobile nodes to have continuous network connectivity to the internet without changing their ip addresses while moving to other networks. The packets sent from Correspondent Node (CN) to a Mobile Node (MN) go first through the mobile node's Home Agent (HA). Then the HA tunnels them to the MN's foreign network. This process of delivering the packets to CN is called triangle routing. Triangle routing problem appears when the indirect path between CN and MN through the HA is longer than the direct path. To overcome triangle routing, Route Optimization (RO) method is added in mobile Pv6. In route optimization, when MN changes its location, it sends a Binding Update (BU) to CN informing its CoA. To secure these Binding Updates, we present a new protocol called ＂Certificate Based Inquisition Approach＂ for securing Binding Updates in RO. Performance analysis of this shows that it is computationally efficient than RR protocol and is not susceptible to any security attacks. To show the effectiveness of the proposed technique, it is compared with the state of art of other RO protocols. Simulation results presented in this study are based on the ns2 mobility software on linux platform. The simulations results show that our proposed technique achieves better performance than the Return Routability (RR), Certificate Based Binding Update protocol (CBU), Hierarchical Certificate Based Binding Update protocol (HCBU).
