WARP-based Experiments of Configurable Beamforming on Physical Layer Security

چکیده
This work investigates a novel approach called configurable beamforming on wireless physical layer security against passive eavesdroppers with Wireless Open-Access Research Platform (WARP). The aim is to create physical regions surrounding the intended user by configuring antenna array. By adapting the array configuration according to the intended user’s channel state information, it allows the vulnerability of the physical regions to eavesdropping to be reduced. The theory analysis and implementation on WARP is examined in this work. Two WARP boards are deployed in a room where one with an antenna array serves as the access point and the other one serves as a general user. A range of antenna array configurations are investigated. Results using the real studies are then used to advise on the optimum array configuration for a user traversing a coverage area.

Distance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملPhysical layer security of MIMO-OFDM systems by beamforming and artificial noise generation
In this paper we address physical layer security in MIMO frequency selective wireless channels in the presence of a passive eavesdropper, i.e., the associated channel is unknown to the transmitter. Signalling is based on orthogonal frequency division multiplexing (OFDM). Spatial beamforming and artificial noise broadcasting are chosen as the strategy for secure transmission. The contribution of...
