Recently, Altaf et al. proposed a novel authentication and key‐agreement scheme for satellite communication network. In this paper, we will prove that Altaf et al.'s scheme cannot provide perfect forward secrecy and resist the off‐line password guessing attack and user impersonation attack. To overcome these weaknesses, we propose an enhanced dynamic authentication scheme for mobile satellite communication systems, making use of the advantages of one‐way hash function and the discrete logarithm problem. We formally prove the security of the proposed scheme under the widely used BPR adversary model, and the heuristic discussion shows that the new scheme has good security and can resist all kinds of known malicious attacks. In addition, by comparing with other related schemes, we find that our scheme has better performance.

用于移动卫星通信系统的增强型动态认证方案

最近,Altaf等。提出了一种新颖的卫星通信网络认证和密钥协商方案。在本文中,我们将证明Altaf等人的方案无法提供完美的前向保密性,无法抵抗离线密码猜测攻击和用户假冒攻击。为了克服这些缺点,我们利用单向哈希函数和离散对数问题的优点,为移动卫星通信系统提出了一种增强的动态认证方案。我们在广泛使用的BPR对手模型下正式证明了该方案的安全性,启发式讨论表明新方案具有良好的安全性,可以抵抗各种已知的恶意攻击。另外,通过与其他相关方案进行比较,我们发现该方案具有更好的性能。
