一种基于位置的WSAN密钥预分配方案

论文从无线传感器和执行器网络的信息传输方式出发，提出一种新的密钥预分配方案。方案充分利用执行器节点具有能量充足、存储器资源丰富、较强计算和通信能力等特点，结合部署位置信息，在执行器节点-执行器节点和执行器-传感器节点两个通信层上采用不同的密钥预分配方案。通过分析可知，新方案在连通性、安全性、计算和通信消耗上都有良好性能。

A Location-Based Key Pre-Distribution Scheme for Wireless Sensor and Actor Network

This paper proposes a new scheme for key pre-distribution, based on the way of intelligent transmission for the wireless sensor and actor networks. The scheme makes full use of the character of actor node that has sufficient energy, rich memory resources and strong computation and correspondence capacity, and used different plan in the actoractor layer and actor-sensor layer by combining the deployment information. The analysis indicates that the new scheme has a good performance in the connectivity, the security, and the computation consumption
