Compared with the related schemes the proposed scheme achieves the following three main advantages 1 It is just based on a secure one-way hash function for avoiding complex computations for both mobile users and network control center NCC 2 it does not require sensitive verification table which may cause NCC to become an attractive target for numerous attacks . insertion attacks and stolen-verifier attacks and 3 it provides higher security level . secure mutual authentication and key establishment confidential communication user s privacy simple key management and session key independence . As a result the proposed scheme is very suitable for lightweight-device environments because of very low computation overload on the part of both mobile user and NCC. Keywords mobile satellite communication system user authentication key establishment public-key management anonymity 1 Introduction Recently mobile satellite communication systems have captured much attention because these systems provide the opportunity to make personal communication as broad as possible 1-11 . Within mobile satellite communication systems the problem arises how to mutually authenticate each other and whether confidentiality of communication is guaranteed. In 1996 Cruickshank 12 first proposed a security system for satellite networks. In the Cruickshank s scheme public-key cryptosystem PKC is used to provide authentication between a mobile .
