无线传感器网络安全数据融合算法研究

The Research on Algorithm of Secure Aggregation in WSN

在无人监管和恶劣的环境下,节点被捕获对无线传感器网络的安全构成了极大的威胁,被捕获的节点能发送伪造的数据以改变整个融合结果,这样就为融合结果引入了不确定性,为了抵抗节点被捕获的攻击以及量化融合结果中的不确定性,文中提出了一种基于信任的融合构架解决了融合过程中存在的安全问题。

In unattended and hostile environments, node capture can become a disastrous threat to wireless sensor. In order to change the whole aggregation result, the captured nodes can send bogus data, thus introdcing introduce uncertainty in the aggregation results. To make aggregation resilient to node capture and quantify uncertainty in aggregation result, RBSA（Reputation Based Framework for Secure Data Aggregation） is proposed, which could solve security problem in the porcess of aggregation.
