摘要: Ad hoc网络作为一种无线移动网络正成为网络研究中的热点之一。由于其灵活方便的组网方式,Ad hoc网络在军事领域受到广泛的重视,并正在逐步应用于商业领域。但是,安全问题始终是Ad hoc网络的一个弱点,而身份认证对于无线移动自组的Ad hoc网络特别重要,是实现整个Ad hoc网络安全机制的首要步骤。论文提出一种基于椭圆曲线的门限身份认证方案,利用拉格朗日定理生成群密钥并利用椭圆曲线数字签名算法生成子证书并合成,该算法的安全性、高效率以及低计算复杂度特别适合Ad hoc网络移动自组的特点。

Abstract: Ad hoc network is turning to be a hotspot of research.Characteristics of mobility and self-organization make the ad hoc network to be widely marked in the military field and gradually applicable in the commercial field.However,the security,especially the authentication is crucial for the wireless mobile ad hoc network.In this paper,a threshold authentication scheme of ad hoc network based on elliptic curve is proposed,in using Lagrange Theorem to generate the group key and in using the digital signature algorithm based on elliptic curve to generate and merge the sub certificates.The high security,efficiency and low complexity of computing are especially proper for the unique characteristics of ad hoc network.
