Wireless Physical Layer Security
Security in wireless networks has traditionally been considered to be an issue to be addressed separately from the physical radio transmission aspects of wireless systems. However, with the emergence of new networking architectures that are not amenable to traditional methods of secure communication such as data encryption, there has been an increase in interest in the potential of the physical...
متن کاملPhysical Layer Security in Wireless Communication Networks
Physical layer (PHY) security has become an emerging area of research recently. Wireless networks use unguided medium as communication channels, so gathering wireless data transmission is easier when compared to traditional cable systems. With the rise of new security challenges, many different solutions have been offered and are being developed. However, maintaining security in wireless networ...

متن کاملOptimal Beamforming for Physical Layer Security in MISO Wireless Networks
A wireless network of multiple transmitter-user pairs overheard by an eavesdropper, where the transmitters are equipped with multiple antennas while the users and eavesdropper are equipped with a single antenna, is considered. At different levels of wireless channel knowledge, the problem of interest is beamforming to optimize the users’ quality-of-service (QoS) in terms of their secrecy throug...
متن کاملPhysical layer security in wireless networks : design and enhancement
Security and privacy have become increasingly significant concerns in wireless communication networks, due to the open nature of the wireless medium which makes the wireless transmission vulnerable to eavesdropping and inimical attacking. The emergence and development of decentralized and ad-hoc wireless networks pose great challenges to the implementation of higher-layer key distribution and m...
