In 2009 and 2011, Chen et al. and Lasc et al. proposed two separate authentication schemes for mobile satellite communication systems. Unfortunately, their schemes are unable to protect security in the event of smart card loss. In this paper, we propose a novel version that resists common malicious attacks and improves both the schemes of Chen et al. and Lasc et al. The security of our scheme is based on the discrete logarithm problem and one-way hash function. A nonce mechanism is also applied to prevent replay attack. Furthermore, our scheme is more efficient than related schemes and thus more suitable for being implemented in satellite communication systems.
