摘要
针对无线传感网节点群组通信存在的安全问题,在无线传感器网络上设计并实现了基于椭圆曲线的固定轮数的群组密钥协商协议。从设计和实现的角度,首先,对椭圆曲线标量乘进行基于NAF表示法的窗口滑动技术优化;然后,分析群组密钥协商协议在传感器网络上存在的问题,提出了数据流驱动网络协议解决方案;最后,在国产无线传感器节点GAINST-CC2430上,首次使群组密钥协商协议在实际无线传感器网络上得到实现。
To solve the security problem existing in wireless sensor network node group, a round fixed group key agreement protocol based on ECC was designed and implemented. From the point of view of de- sign and implementation, window sliding technique based on NAF expression was integrated to optimize the scalar multiplication in ECC firstly. Then considering the problem in implementation on the real wire- less sensor network, a data stream driving protocol solution was proposed. Finally all design was imple- mented on homebred wireless sensor network nodes GAINST-CC2430 which is the first group key agree- ment protocol implementation on actual wireless sensor network.
