A Practical Authentication with Key Agreement Protocol for Satellite Communications on ECC
Huihui Huang, Jiameng Chen, Baojun Huang · 2015
Due to geographic and environment limitations, traditional personal communication systems broadcast week and delay signals [1][2].In the last decade, considerable attention has been paid to the low-earth-orbit satellite communications system (LSC system) for its numbers of advantages: Short transmission delay, small attenuation signal, large communication area and far broadcasting range [2][3][4][5][6][7][8][9].The main components in a LSC system are the low-earth-orbit satellites, the network control center (NCC), the gateways and the mobile devices [8].Recently, we analyze the security aspects of Chang et al's scheme [9] and identify many loopholes that are common of other related scheme [7][8][9][10][11][12].Therefore, an enhanced authentication protocol is proposed using elliptic curve cryptosystem (ECC) and identity-based cryptography (IBC) in threeround handshake identification system.The scheme not only provides seven essential requirements but also counter the strong new DoS attack.The paper is organized as follows.Section 2 gives preliminaries.The scheme is introduced in Section 3. Section 4 discusses the security of the scheme.We draw some concluding remarks in Section 5.
