摘要
基于双线性函数,提出了一个存储最优的传感器网络密钥共享方法,指出了当前密钥管理协议在传感器网络中的不适用性。并对该共享方法的安全性和性能(存储、计算、通信)进行了分析。与其他方法相比,具有以下优点:(1)存储最优,只要求每个节点保存一个密钥和H ash函数,存储量与网络规模无关;(2)网络是确定连通的;(3)具有节点鉴别能力。因此,该方法能在较低耗费的前提下实现安全的、存储最优的、确定连通的传感器网络密钥共享。
A storage-optimal key sharing scheme with authentication is presented based on bilinear mapping. The secure communications over the resource constrained devices are extended. And its security and the overload（including storage, computation and communication） are analyzed. Compared with the previously proposed schemes, the scheme has the following advantages： （1）It is optimal in memory consumption. Each sensor node is only required to hold one secret key and Hash functions, which is independent of the scale of network; （2）The sensor network is guaranteed to be wholly connected; （3）The node authentication is also provided. Finally, the result proves that the scheme is secure, storage optimal, and deterministically wholly-connected with the moderate energy consumption.
