Information Security of PHY Layer in Wireless Networks

Information Security of PHY Layer in Wireless Networks

Since the characteristics of wireless channel are open and broadcasting, wireless networks are very vulnerable to be attacked via eavesdropping, jamming, and interference. As traditional secure technologies are not suitable for PHY layer of wireless networks, physical-layer security issues become a...
