In order to enhance the route optimization mode, the OMIPv6 and CGA-OMIPv6 protocols have been proposed. They use public key methods to minimize the amount of signaling messages and handover latency. However, since the public key operations are computationally expensive, it is so difficult for the protocols to support low-power mobile nodes. In this paper, we propose an enhanced OMIPv6 protocol. By employing the home agent as a security proxy, the proposed protocol improves the CGA-OMIPv6 protocol to support low-power mobile nodes. As a result, the proposed protocol significantly reduces the computational cost of the mobile node into just two HMAC and two hash operations. Furthermore, it achieves good scalability and manageability through the bind between the home agent’s address and public key.
