Physical Layer Security in RIS-Assisted THz-Enabled LEO Satellite Communications

IEEE Open Journal of the Communications Society
Satellite networks are expected to play a key role in achieving global coverage in the sixth generation (6G) of wireless communications systems. Despite their potential, the operation of extensive satellite constellations introduces distinct challenges ...

Physical-layer security for the internet of things.

, 2017
Das Internet der Dinge (IoT), bei dem Kommunikationsknoten durch eingebettete Kleinstsystemen gebildet werden, gewinnt an wirtschaftlicher Bedeutung. Durch den enormen Preisdruck stellt sich jedoch eine große Herausforderung dar, die Nachfrage nach erhöhter Sicherheit im IoT zu realisieren. In dieser Arbeit untersuchen wir einen neuen Sicherheitsansatz,

Quantization for Physical Layer Security

2016 IEEE Globecom Workshops (GC Wkshps), 2016
We propose a multi-level CSI quantization and key reconciliation scheme for physical layer security. The noisy wireless channel estimates obtained by the users first run through a transformation, prior to the quantization step. This enables the definition of guard bands around the quantization boundaries, tailored for a specific efficiency and not ...

Securing massive MIMO at the physical layer

2015 IEEE Conference on Communications and Network Security (CNS), 2015
We consider a single-cell downlink massive MIMO system in the presence of an adversary capable of jamming and eavesdropping. We show that, classical attacks of eavesdropping and data jamming can be simultaneously rendered useless. Specifically, we show that, the secure degrees of freedom (DoF) attained in the presence of classical attacks is as same as
