| 摘 要： | 提出一种能根据路由节点的剩余能量动态选择簇头的低能耗动态簇组网模型,并设计了相应的密钥管理方案.与以往的密钥管理方案相比,该方案给出一种新型密钥链,能确保某个传感节点预置密钥的丢失不威胁其他节点的安全性；提出三种以Hash函数为主的轻量级密码协议,能以低能耗的方式完成网络节点间的认证与簇密钥的分配；给出密码协议安全性的形式化分析,确保了协议本身的安全性.分析表明,该方案能够支持网络的扩展,并具有较好的安全性.

| Abstract: | An energy-saving dynamic cluster networking model that chooses cluster heads according to router nodes’ remnant energy is proposed.Its corresponding key management scheme is designed too.In contract to previous key management schemes,the proposed novel type of key chain can ensure the loss of one sensor node’s preset key doesn’t threaten the safety of other nodes.Three lightweight cryptographic protocols that mainly consist of Hash functions are proposed to complete at low energy costs the authentication between network nodes and the allocation of cluster keys.Formal analysis on cryptographic protocol security is put forward which ensures the safety of these protocols themselves.Analyses show that the scheme can support network expansion as well as bearing security. |
