SUMMARY 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. Copyright © 2012 John Wiley & Sons, Ltd.
