In this paper, a credit-based user authentication scheme is proposed for delay tolerant mobile wireless networks. The proposed authentication scheme isolates the uncertain network condition in the high-delay wireless backhaul with high error rate, and accelerates the overall authentication process when the mobile terminal roams in the visited network. The performance evaluation demonstrates that the proposed credit-based authentication scheme is secure and effectively reduces the overall delay and overhead in user authentication for delay tolerant mobile wireless networks.
