移动Ad Hoc网络中带路由机制的密钥管理

Key Management with the Routing Mechanism in Mobile Ad Hoc Networks

移动Ad Hoc网络是一种无中心自组织的多跳无线网络,有效的密钥管理是网络安全的关键。因此,本文提出了一个能够快速响应的密钥管理框架。这个框架通过应用可验证的秘密共享方案来建立PKI,并通过引入路由机制构造了一个快速响应的服务器组。服务器组可以对组内结点的私钥分量更新和所有结点的证书更新提供快速响应。为了验证框架的性能,本文通过仿真给出了实验结果。

Mobile ad hoc networks are multihop wireless networks which are acentric and self-organizing,and effective key management is the linchpin of network security.So a key management framework,which responds rapidly in mobile ad hoc networks,is proposed.The framework establishes PKI by applying a verifiable secret sharing scheme,and constructs a server group that responsds rapidly by introducing a routing mechanism to the framework.The server group responsds rapidly in secret share updating in the server group and certificate updating for all nodes.Simulation results are given for validating the framework performance.
