【摘要】 将组合公钥技术和门限密码理论结合应用于移动自组网的密钥管理方案中。利用密钥分发机构对整个网络进行初始化。在网络运行阶段,设计一种动态调整分享秘密的服务节点数目以及门限值大小的方案,给出节点退出和新节点加入网络的处理方法。该密钥管理方案安全、高效、灵活,能较好地适应移动自组网的特点。更多还原

【Abstract】 Combined public key and threshold cryptography are applied to key management for Mobile Ad Hoc Network(MANET) in this paper.The Key Distribution Center(KDC) is used for the initialization of the whole network.In the operation phase,a scheme is proposed to dynamically change the number of server nodes and the threshold value.The method about how to deal with the new node addition and the node eviction is given.The key management scheme is secure,efficient and flexible,so it is especially suitable for the characteristics of MANET.更多还原
