摘　　要：在分析现有的异构无线网络分布式信任方案基础上,提出了一种有效的基于门限的密钥管理方案。该方案实现了节点之间的双向认证,不仅能满足前向安全性和后向安全性,而且能有效抑制拒绝服务攻击。仿真结果表明,该方案安全高效,适合基于蜂窝网络和Ad Hoc网络的异构无线网络融合系统。Following the analysis of existing distributed trust model to heterogeneous wireless network,this paper proposes an effective key management scheme based on threshold.The scheme achieves two-way authentication between the nodes.It can not only satisfy the forward confidentiality and backward confidentiality,but also resist denial of services.The performance of simulations shows that the scheme is secure and effective;the scheme is suited to heterogeneous wireless network based on cellular networks and Ad Hoc networks.
