Abstract: As increasing use of wireless networks like Mobile IP Networks (MINET) or Wireless Sensor Networks (WSNs) in day to day life its security requirements and privacy preserving requirements becomes important research challenge. The security of such networks is mainly achieved with use of security and privacy aware routing methods. Additionally, the efficiency of such networks is mainly depends on use of routing protocols. There are many routing methods introduced by researchers with objectives of privacy preserving, authentication and secure communications for MINETs. But most of methods are failed to achieve both efficient user authentication and secure communication while achieving the Quality of Service (QoS) requirements of mobile IP networks. For roaming services in mobile networks, Priauth protocol recent designed which is showing the efficient performance in terms of time and overhead parameters. For mobile wireless networks, along with privacy preservation, secure communication method designing is also challenging task. This study presents the novel HPriauth (Hybrid Priauth) routing method with goal of achieving multi-objectives like privacy preservation and secure data communication. For authentication and privacy preservation we designed roaming scenario based steps and for data security we designed onion routing based steps. This study is presenting both steps in HPriauth for MINET with its simulation analysis. From the simulation results, HPriauth is out performing all previous methods.
