在本文中，我们提出了SeGrid，在低占空比传感器网络中建立网格密钥的一个安全框架，为每对相邻传感器建立一个公共密钥是不必要的，因为大多数传感器在任何时刻都保持在睡眠模式。SeGrid打算为可能是多跳的两个网格计算共享密钥。这种设计探索了这样一个事实，即对于大多数应用程序来说，更紧密的网格具有更高的概率和安全消息交换的需求。SeGrid依赖于低成本公共密码系统的可用性。通过一种新的管理协议来控制对相应公共份额的查询和更新，使得两个网格越近，获得彼此公共份额的距离越短。我们基于Blom的密钥建立实例化SeGrid来说明网格密钥的计算。
In this paper, we propose SeGrid, a secure framework for establishing grid keys in low duty cycle sensor networks, for which establishing a common key for each pair of neighboring sensors is unnecessary since most sensors remain in sleep mode at any instant of time. SeGrid intends to compute a shared key for two grids that may be multihop away. This design explores the fact that for most applications, closer grids have higher probability and desire for secure message exchange. SeGrid relies on the availability of a low-cost public cryptosystem. The query and update of the corresponding public shares are controlled by a novel management protocol such that the closer the two grids, the shorter the distance to obtain each other's public share. We instantiate SeGrid based on Blom's key establishment to illustrate the computation of a grid key.
