Efficient dynamic authentication for mobile satellite communication systems without verification table

Abstract

The mobile satellite system is an important wireless communication system widely used nowadays. The issue of protecting the transmission security in low-earth-orbit satellite networks thus becomes more and more critical. It is known that several authentication schemes for satellite communication systems have been proposed to deal with the issue. However, previous protocols either employ complicated public key computation or have to maintain a verification table. In this paper, the author will introduce a new dynamic authentication protocol for mobile satellite communication systems without using a verification table. The comparison results will also show that the proposed scheme has lower computational costs. Copyright © 2014 John Wiley & Sons, Ltd.
