基于簇结构的移动Ad Hoc网络的认证协议

与传统网络比较，移动AdHoe网络具有拓扑结构不稳定、终端能源有限、有限带宽及自组织等特点，这使得AdHoe网络的安全问题成了一个极具挑战性的研究课题，而安全问题中认证是基础。文中提出一种基于分簇结构的移动AdHoe网络的认证协议，结合门限加密机制和分布式密钥管理方案，实现各级簇头及簇成员的分布式认证。有效防止了恶意节点对消息的截取、修改、伪造、监视和窃听等外部攻击和防范内部被攻破认证节点对分布式认证的干扰。

Authentication Protocol in Hierarchical-Cluster-Based Mobile Ad Hoc Networks

Dissimilar to traditional networks,mobile Ad Hoc network owes to the features of topology instability,terminal energy source finitude,bandwidth limited and self-organization excite makes security becomes a most challenging study issue in mobile Ad Hoc networks,whereas authentication is basis.In this paper,propose an authentication protocol in hierarchical-cluster-based mobile Ad Hoc networks,associating threshold cryptography mechanism with distributed key management scheme,which implements distributed authentication of cluster head of all levels and cluster members.Has prevented the malicious node effectively to the news interception,modification,forge,surveillance and interception and so on.And avoided the interior authentication point broken to the distributional authentication disturbance.
