We introduce a protocol with a reconfigurable filter system to create non-overlapping single loops in the smart power grid for the realization of the Kirchhoff-Law-Johnson-(like)-Noise secure key distribution system. The protocol is valid for one-dimensional radial networks (chain-like power line) which are typical of the electricity distribution network between the utility and the customer. The speed of the protocol (the number of steps needed) versus grid size is analyzed. When properly generalized, such a system has the potential to achieve unconditionally secure key distribution over the smart power grid of arbitrary geometrical dimensions.
我们提出了一种协议，其中包含一个可重构滤波器系统，以在智能电网中创建非重叠的单环，从而实现基尔霍夫-约翰逊（类似）噪声安全密钥分发系统。该协议适用于一维径向网络（链式电源线），这是典型的公用事业和客户之间的配电网。我们分析了协议的速度（即所需的步骤数）与网格大小的关系。当适当推广时，这样的系统有可能在任意几何尺寸的智能电网中实现无条件安全的密钥分发。
