无线网络在民用和军事应用中起着极为重要的作用。但是，通过无线网络的信息传输安全仍然是一个具有挑战性的问题。至关重要的是要确保仅适用于预期用户而不是入侵者的机密数据。堵塞和窃听是无线网络物理层的两次主要攻击。本文提供了一些有关几种普遍方法的教程，以增强无线网络中物理层的安全性。我们根据它们的特征特征将这些方法分类为五个类别，每个类别都用两个指标进行了讨论。首先，我们比较了他们的秘密频道容量，然后在详尽的关键搜索中显示了它们的计算复杂性。最后，我们通过有关这两个指标的一些示例来说明他们的安全要求。
Wireless networking plays an extremely important role in civil and military applications. However, security of information transfer via wireless networks remains a challenging issue. It is critical to ensure that confidential data are accessible only to the intended users rather than intruders. Jamming and eavesdropping are two primary attacks at the physical layer of a wireless network. This article offers a tutorial on several prevalent methods to enhance security at the physical layer in wireless networks. We classify these methods based on their characteristic features into five categories, each of which is discussed in terms of two metrics. First, we compare their secret channel capacities, and then we show their computational complexities in exhaustive key search. Finally, we illustrate their security requirements via some examples with respect to these two metrics.
