Editorial: Physical Layer Security and Wireless Access Control (QSHINE 2017)

Wi-Fi has become a predominant means of communication. However, the problem of unauthorized access to Wi-Fi network has become increasingly severe. Physical-layer security is emerging as a promising approach for supporting new and existing security services. Using properties of physical-layer communication channels in security mechanisms can potentially enhance conventional security services and assist in mitigating threats that challenge the capabilities of conventional cryptographic mechanisms, such as spoofing attack, relay attacks, ad-hoc key establishment and key-less secure communication. However, significant challenges, including security evaluation and guarantees, remain to be solved to realize practical physical-layer security mechanisms. …
