Physical layer security (PLS) solutions for passive eavesdropping in wireless communication [PDF]
, 2022 An absolute secured wireless communication is unattainable. Nevertheless, communication models must be secure and unique across each layer of the model. The physical layer is the easiest layer through which information leaks, due to its broadcast nature.
