一种基于位置的动态网络安全认证机制

摘要

在无线网络的密钥管理机制中，位置信息越来越令人瞩目。然而，节点移动性限制了位置信息在动态网络密钥管理机制中的优势。为了解决这个问题，建立了一种基于位置的动态网络安全认证机制。在此机制中，利用节点的地理位置信息建立了基于位置的密钥管理机制及密钥更新策略，在保障节点位置可靠的同时达到安全通信的目的。%The location information is more and more remarkable in the key management mechanism for wireless networks. However, because of the node mobility in dynamic networks which makes location information to be difficult to play out advantage in key management mechanism. In order to solve the problem, a location-based security authentication mechanism is provided for dynamic network. On the basis of adopting location-based key, this mechanism updates keys timely. Finally the purpose of safe communication is achieved with taking advantages of location information.
