Abstract:

Space information network composed of a variety of heterogeneous networks is widely concerned.However,the space information network is facing more security threats and more likely to roam due to its complex topology and large user scale.Considering the characteristics of space information network,a secure authentication enhancement scheme for seamless handover and roaming in space information network was presented.The fast mutual authentication and reasonable accounting between the user and the visiting domain based on the combination of Token and Hash chain was achieved.In addition,two seamless handover mechanisms were proposed to ensure the continuity of user communication.Finally,security analysis indicates that the scheme can not only provide essential security properties,but also achieve reasonable accounting.

Key words: space information network, roaming, seamless handover, secure authentication, accounting
