Wireless Physical-Layer Security: Lessons Learned From Information Theory

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...

Physical 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...

From Quantum to Wireless: A Step Towards Physical-Layer Security

Quantum information theory is widely recognized as an arguably powerful paradigm for physically secure communications. In general, any attack that an eavesdropper, say Eve, perpetrates in order to gain access to messages or keys exchanged by the legitimate parties, say Alice and Bob, will result in disturbances to quantum states that can be detected with overwhelming probability — security is g...
