【摘要】 传感器网络中的节点存在由于能量耗尽或恶意攻击而丧失作用的威胁,因此需要新节点的加入.利用Bloom Filter技术,提出了一种访问控制协议.本协议不仅便于实现新节点、旧节点的双向认证和密钥协商,而且便于实现节点的加入与撤消.通过性能分析和安全性分析说明了该协议的有效性.更多还原

【Abstract】 Nodes in a sensor networks may be lost because of power exhaustion or malicious attacks.Therefore it′s necessary for new nodes′ deployment.Using Bloom Filter,we propose an access control protocol including the mutual authentication procedure and common key generation.It′s efficient for the nodes′ adding,deleting and authentication.At last,the paper makes an analysis of the performance and safety about the proposed protocol.更多还原
