论文摘要
无线介质的广播性质使对窃听者的接触成为潜在的威胁。物理层安全性（PLS）已被广泛认为是对加密补充的有前途的安全措施。最近已经证明，可以使用Spectrum编程增强的软件定义网络（SDN）来实施PLS，在该设备上，网络控制器能够执行智能访问点（AP）选择算法，以便可以实现PLS，并可以实现PLS的能力和秘密能力。在本文中，我们为此类实施提供了基本的系统模型。我们还引入了一种新型的保密能力优化算法，其中我们将智能AP选择与未选择的AP相结合的AP选择与友好的干扰（FJ）相结合。
The broadcasting nature of the wireless medium makes exposure to eavesdroppers a potential threat. Physical Layer Security (PLS) has been widely recognized as a promising security measure complementary to encryption. It has recently been demonstrated that PLS can be implemented using off-the-shelf equipment by spectrum-programming enhanced Software-Defined Networking (SDN), where a network controller is able to execute intelligent access point (AP) selection algorithms such that PLS can be achieved and secrecy capacity optimized. In this paper, we provide a basic system model for such implementations. We also introduce a novel secrecy capacity optimization algorithm, in which we combine intelligent AP selection with the addition of Friendly Jamming (FJ) by the not-selected AP.
