Due to the wireless techniques develop rapidly and universality of mobile devices, so people use mobile devices to access Internet, anytime-anywhere. Recently, vehicular network is broadly to apply to the Intelligent Transportation System (ITS) and it gains significant attention in the field of industry and academic. Moreover, there are many standards and protocols provided for vehicular networks. Vehicular networks have the characters of high mobility and high variant. In vehicular networks, it supports two kinds of communication environments: vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication, but these communications among devices or infrastructures are used by wireless network. Thus, the key point of this thesis is how to achieve the secure and efficient mobility management. In the security aspect, the topic of network security is always a hot issue. Everyone accesses the Internet is insecure because the wireless network is opened and shared medium. Moreover, the users may suffer from all kinds of attacks (e.g., modification, forge, and replay attacks). Hence, the authentication mechanism is a basic protection for valid user. In this thesis, we propose many authentication mechanisms to prevent from the attacks. Moreover, the session key is generated for the secure communication after the authentication mechanism is finished. In the mobility management aspect, the traditional mobility management (e.g., Mobile IPv6) needs to be modified because the vehicles have high mobility resulting in long handoff latency or failed handoff. Moreover, the amounts of devices are very huge so this situation causes a lot of signaling overhead in mobility management. Thus, Internet Engineering Task Force (IETF) proposed a solution called network mobility (NEMO) basic support protocol to reduce the signaling overhead of mobility management. In addition, the IETF NETLMM working group proposed Proxy Mobile IPv6 (PMIPv6), a network-based localized mobility management protocol to support mobility management without the participation of mobile nodes (MNs) in any mobility-related signaling. However, NEMO and PMIPv6 protocols still have some drawbacks. Therefore, this thesis overcomes the disadvantages of NEMO and PMIPv6 protocols, proposes fast handoff schemes, and reduces the handoff latency in mobile networks. In this thesis, the main contributions are to provide fast handoff schemes in mobile networks and secure mutual authentication mechanisms in vehicular networks. Moreover, we integrate the authentication mechanism into the mobility management scheme without increasing the signaling overhead.
