ONE-TIME KEY AND DIAMETER MESSAGE AUTHENTICATION PROTOCOL FOR PROXY MOBILE IPV6

The working group of NetLMM has proposed a new approach, known as network-based mobility management protocol that is actively standardized by Internet Engineering Task Force called Proxy Mobile IPv6 where many mobility signaling messages are performed by a network entity on behalf of a mobile host. Proxy Mobile IPv6 is an effective mobility management protocol for next generation wireless networks that are expected to enable network access ubiquity. Proxy Mobile IPv6 has salient features that attract a lot of attention among the telecommunication and Internet communities. However, Proxy Mobile IPv6 stills suffer from lengthy handover latency and packet loss when Mobile Host moves away to a new network with high speed mobility during the handover process. In order to improve the performance of Proxy Mobile IPv6, we proposed a solution scheme with integration of Media Independent Handover and neighbor discovery message of IPv6 to reduce handover latency and packet loss. But, this proposed protocol does not have methods to prevent security threats such as replay attack and key exposure when mobile host first enters into Proxy Mobile IPv6 domain and also during the handover process. In order to protect this proposed protocol, an authentication method based on the authentication protocol is presented in this paper that can prevent security threats. Also, this authentication method reduces authentication latency.
