A Handover Authentication Scheme based on Security Associations for NEMO in Aeronautical Telecommunications Network

Abstract

Abstract.As an extension of Mobile IPv6, the NEMO is needed to support session continuity for each mobile network node(MNN) across different access networks in aeronautical telecommunications network(ATN). However, the existing schemes of NEMO don't mention the authentication issues in handover procedure, which make it unsuitable for the ATN. In this paper, a handover authentication scheme based on security associations(HASA) is proposed for NEMO in ATN environment. HASA authenticates care-of address and prefix separately. The performance analysis shows that HASA not only mitigates the tunneling burden and decrease the handover lantency but also provides a higher level of security over NBSP and FMIPv6 .
